2024-10-17 RELEASE 7.1.1

This minor release removes the dependency on some only Python packages, in particular six which is a problem for some Linux distributions that ship RDFLib.

Other than that, there are a few minor PRs that improve testing and to do with making releases - no new RDFLib core work.

2024-10-17 RELEASE 7.1.0

This minor release incorporates just over 100 substantive PRs - interesting things submitted by people - and around 140 auto-generated update PRs from dependabot and similar.

There are no major changes in this release over 7.0.0 and this release can be used in place of 7.0.0 without much worry about altered behaviour.

Since the previous release, we have updated the way auto-generated PRs are handled to ease the job of maintainers.

Due to the large numbers of PRs contained in this release, an abbreviated listing of them only is provided here:

2023-08-02 RELEASE 7.0.0

This is a major release with relatively slight breaking changes, new features and bug fixes.

The most notable breaking change relates to how RDFLib handles the publicID parameter of the Graph.parse and Dataset.parse methods. Most users should not be affected by this change.

Instructions on adapting existing code to the breaking changes can be found in the upgrade guide from Version 6 to Version 7 which should be available here.

It is likely that the next couple of RDFLib releases will all be major versions, mostly because there are some more shortcomings of RDFLib’s public interface that should be addressed.

If you use RDFLib, please consider keeping an eye on discussions, issues and pull-requests labelled with “feedback wanted”.

A big thanks to everyone who contributed to this release.

BREAKING CHANGE: don’t use publicID as the name for the default graph. (#2406)

Commit 4b96e9d, closes #2406.

When parsing data into a ConjunctiveGraph or Dataset, the triples in the default graphs in the sources were loaded into a graph named publicID.

This behaviour has been changed, and now the triples from the default graph in source RDF documents will be loaded into ConjunctiveGraph.default_context or Dataset.default_context.

The publicID parameter to ConjunctiveGraph.parse and Dataset.parse constructors will now only be used as the base URI for relative URI resolution.

  • Fixes https://github.com/RDFLib/rdflib/issues/2404

  • Fixes https://github.com/RDFLib/rdflib/issues/2375

  • Fixes https://github.com/RDFLib/rdflib/issues/436

  • Fixes https://github.com/RDFLib/rdflib/issues/1804

BREAKING CHANGE: drop support for python 3.7 (#2436)

Commit 1e5f56b, closes #2436.

Python 3.7 will be end-of-life on the 27th of June 2023 and the next release of RDFLib will be a new major version.

This changes the minimum supported version of Python to 3.8.1 as some of the dependencies we use are not too fond of python 3.8.0. This change also removes all accommodations for older python versions.

feat: add curie method to NamespaceManager (#2365)

Commit f200722, closes #2365.

Added a curie method to NamespaceManager, which can be used to generate a CURIE from a URI.

Other changes:

Fixes https://github.com/RDFLib/rdflib/issues/2348.

feat: add optional target_graph argument to Graph.cbd and use it for DESCRIBE queries (#2322)

Commit 81d13d4, closes #2322.

Add optional keyword only target_graph argument to rdflib.graph.Graph.cbd and use this new argument in evalDescribeQuery.

This makes it possible to compute a concise bounded description without creating a new graph to hold the result, and also without potentially having to copy it to another final graph.

feat: Don’t generate prefixes for unknown URIs (#2467)

Commit bd797ac.

When serializing RDF graphs, URIs with unknown prefixes were assigned a namespace like ns1:. While the result would be smaller files, it does result in output that is not as readable.

This change removes this automatic assignment of namespace prefixes.

This is somewhat of an aesthetic choice, eventually we should have more flexibility in this regard so that users can exercise more control over how URIs in unknown namespaces are handled.

With this change, users can still manually create namespace prefixes for URIs in unknown namespaces, but before it there was no way to avoid the undesired behaviour, so this seems like the better default.

feat: Longturtle improvements (#2500)

Commit 5ee8bd7, closes #2500.

Improved the output of the longturtle serializer.

fix: SPARQL count with optionals (#2448)

Commit 46ff6cf, closes #2448.

Change SPARQL count aggregate to ignore optional that are unbound instead of raising an exception when they are encountered.

fix: GROUP_CONCAT handling of empty separator (issue) (#2474)

Commit e94c252, closes #2474.

GROUP_CONCAT was handling an empty separator (i.e. "") incorrectly, it would handle it as if the separator were not set, so essentially it was treated as a single space (i.e. " ").

This change fixes it so that an empty separator with GROUP_CONCAT results in a value with nothing between concatenated values.

Fixes https://github.com/RDFLib/rdflib/issues/2473

fix: add NORMALIZE_LITERALS to rdflib.__all__ (#2489)

Commit 6981c28, closes #2489.

This gets Sphinx to generate documentation for it, and also clearly indicates that it can be used from outside the module.

fix: bugs with rdflib.extras.infixowl (#2390)

Commit cd0b442, closes #2390.

Fix the following issues in rdflib.extras.infixowl:

  • getting and setting of max cardinality only considered identifiers and not other RDF terms.

  • The return value of manchesterSyntax was wrong for some cases.

  • The way that BooleanClass was generating its string representation (i.e. BooleanClass.__repr__) was wrong for some cases.

Other changes:

  • Added an example for using infixowl to create an ontology.

  • Updated infixowl tests.

  • Updated infixowl documentation.

This code is based on code from:

fix: correct imports and __all__ (#2340)

Commit 7df77cd, closes #2340.

Disable implicit_reexport and eliminate all errors reported by mypy after this.

This helps ensure that import statements import from the right module and that the __all__ variable is correct.

fix: dbpedia URL to use https instead of http (#2444)

Commit ef25896, closes #2444.

The URL for the service keyword had the http address for the dbpedia endpoint, which no longer works. Changing it to https as that works.

fix: eliminate bare except: (#2350)

Commit 4ea1436, closes #2350.

Replace bare except: with except Exception, there are some cases where it can be narrowed further, but this is already an improvement over the current situation.

This is somewhat pursuant to eliminating flakeheaven, as it no longer supports the latest version of flake8 [ref]. But it also is just the right thing to do as bare exceptions can cause problems.

fix: eliminate file intermediary in translate algebra (#2267)

Commit ae6b859, closes #2267.

Previously, rdflib.plugins.sparql.algebra.translateAlgebra() maintained state via a file, with a fixed filename query.txt. With this change, use of that file is eliminated; state is now maintained in memory so that multiple concurrent translateAlgebra() calls, for example, should no longer interfere with each other.

The change is accomplished with no change to the client interface. Basically, the actual functionality has been moved into a class, which is instantiated and used as needed (once per call to algrebra.translateAlgebra()).

fix: eliminate some mutable default arguments in SPARQL code (#2301)

Commit 89982f8, closes #2301.

This change eliminates some situations where a mutable object (i.e., a dictionary) was used as the default value for functions in the rdflib.plugins.sparql.processor module and related code. It replaces these situations with typing.Optinal that defaults to None, and is then handled within the function. Luckily, some of the code that the SPARQL Processor relied on already had this style, meaning not a lot of changes had to be made.

This change also makes a small update to the logic in the SPARQL Processor’s query function to simplify the if/else statement. This better mirrors the implementation in the UpdateProcessor.

fix: formatting of SequencePath and AlternativePath (#2504)

Commit 9c73581, closes #2504.

These path types were formatted without parentheses even if they contained multiple elements, resulting in string representations that did not accurately represent the path.

This change fixes the formatting so that the string representations are enclosed in parentheses when necessary.

fix: handling of rdf:HTML literals (#2490)

Commit 588286b, closes #2490.

Previously, without html5lib installed, literals withrdf:HTML datatypes were treated as ill-typed, even if they were not ill-typed.

With this change, if html5lib is not installed, literals with the rdf:HTML datatype will not be treated as ill-typed, and will have Null as their ill_typed attribute value, which means that it is unknown whether they are ill-typed or not.

This change also fixes the mapping from rdf:HTML literal values to lexical forms.

Other changes:

  • Add tests for rdflib.NORMALIZE_LITERALS to ensure it behaves correctly.

Related issues:

fix: HTTP 308 Permanent Redirect status code handling (#2389)

Commit e0b3152, closes #2389 /docs.python.org/3.11/whatsnew/changelog.html#id128.

Change the handling of HTTP status code 308 to behave more like urllib.request.HTTPRedirectHandler, most critically, the new 308 handling will create a new urllib.request.Request object with the new URL, which will prevent state from being carried over from the original request.

One case where this is important is when the domain name changes, for example, when the original URL is http://www.w3.org/ns/adms.ttl and the redirect URL is https://uri.semic.eu/w3c/ns/adms.ttl. With the previous behaviour, the redirect would contain a Host header with the value www.w3.org instead of uri.semic.eu because the Host header is placed in Request.unredirected_hdrs and takes precedence over the Host header in Request.headers.

Other changes:

  • Only handle HTTP status code 308 on Python versions before 3.11 as Python 3.11

    will handle 308 by default [ref].

  • Move code which uses http://www.w3.org/ns/adms.ttl and http://www.w3.org/ns/adms.rdf out of test_guess_format_for_parse into a separate parameterized test, which instead uses the embedded http server.

    This allows the test to fully control the Content-Type header in the response instead of relying on the value that the server is sending.

    This is needed because the server is sending Content-Type: text/plain for the adms.ttl file, which is not a valid RDF format, and the test is expecting Content-Type: text/turtle.

Fixes:

fix: lexical-to-value mapping of rdf:HTML literals (#2483)

Commit 53aaf02, closes #2483.

Use strict mode when parsing rdf:HTML literals. This ensures that when lexical-to-value mapping (i.e. parsing) of a literal with rdf:HTML data type occurs, a value will only be assigned if the lexical form is a valid HTML5 fragment. Otherwise, i.e. for invalid fragments, no value will be associated with the literal [ref] and the literal will be ill-typed.

fix: TriG handling of GRAPH keyword without a graph ID (#2469)

Commit 8c9608b, closes #2469 /www.w3.org/2013/TriGTests/#trig-graph-bad-01.

The RDF 1.1 TriG grammar only allows the GRAPH keyword if it is followed by a graph identifier [ref].

This change enforces this rule so that the

http://www.w3.org/2013/TriGTests/#trig-graph-bad-01 test passes.

fix: TriG parser error handling for nested graphs (#2468)

Commit afea615, closes #2468 /www.w3.org/2013/TriGTests/#trig-graph-bad-07.

Raise an error when nested graphs occur in TriG.

With this change, the http://www.w3.org/2013/TriGTests/#trig-graph-bad-07 test passes.

fix: typing errors from dmypy (#2451)

Commit 10f9ebe, closes #2451.

Fix various typing errors that are reported when running with dmypy, the mypy daemon.

Also add a task for running dmypy to the Taskfile that can be selected as the default mypy variant by setting the MYPY_VARIANT environment variable to dmypy.

fix: widen Graph.__contains__ type-hints to accept Path values (#2323)

Commit 1c45ec4, closes #2323.

Change the type-hints for Graph.__contains__ to also accept Path values as the parameter is passed to the Graph.triples function, which accepts Path values.

docs: Add CITATION.cff file (#2502)

Commit ad5c0e1, closes #2502.

The CITATION.cff file provides release metadata which is used by Zenodo and other software and systems.

This file’s content is best-effort, and pull requests with improvements are welcome and will affect future releases.

docs: add guidelines for breaking changes (#2402)

Commit cad367e, closes #2402.

Add guidelines on how breaking changes should be approached.

The guidelines take a very pragmatic approach with known downsides, but this seems like the best compromise given the current situation.

For prior discussion on this point see:

  • https://github.com/RDFLib/rdflib/discussions/2395

  • https://github.com/RDFLib/rdflib/pull/2108

  • https://github.com/RDFLib/rdflib/discussions/1841

docs: fix comment that doesn’t describe behavior (#2443)

Commit 4e42d10, closes #2443.

Comment refers to a person that knows bob and the code would return a name, but this would only work if the triple person foaf:name bob . is part of the dataset

As this is a very uncommon way to model a foaf:knows the code was adjusted to match the description.

docs: recommend making an issue before making an enhancement (#2391)

Commit 63b082c, closes #2391.

Suggest that contributors first make an issue to get in principle agreement for pull requests before making the pull request.

Enhancements can be controversial, and we may reject the enhancement sometimes, even if the code is good, as it may just not be deemed important enough to increase the maintenance burden of RDFLib.

Other changes:

  • Updated the checklist in the pull request template to be more accurate to current practice.

  • Improved grammar and writing in the pull request template, contribution guide and developers guide.

docs: remove unicode string form in rdflib/term.py (#2384)

Commit ddcc4eb, closes #2384.

The use of Unicode literals is an artefact of Python 2 and is incorrect in Python 3.

Doctests for docstrings using Unicode literals only pass because ALLOW_UNICODE is set, but this option should be disabled as RDFLib does not support Python 2 any more.

This partially resolves https://github.com/RDFLib/rdflib/issues/2378.

2023-03-26 RELEASE 6.3.2

fix: ROUND, ENCODE_FOR_URI and SECONDS SPARQL functions (#2314)

Commit af17916, closes #2314.

ROUND was not correctly rounding negative numbers towards positive infinity, ENCODE_FOR_URI incorrectly treated / as safe, and SECONDS did not include fractional seconds.

This change corrects these issues.

fix: add __hash__ and __eq__ back to rdflib.paths.Path (#2292)

Commit fe1a8f8, closes #2292.

These methods were removed when @total_ordering was added, but @total_ordering does not add them, so removing them essentially removes functionality.

This change adds the methods back and adds tests to ensure they work correctly.

All path related tests are also moved into one file.

fix: Add to_dict method to the JSON-LD Context class. (#2310)

Commit d7883eb, closes #2310.

Context.to_dict is used in JSON-LD serialization, but it was not implemented. This change adds the method.

fix: add the wgs namespace binding back (#2294)

Commit adf8eb2, closes #2294.

https://github.com/RDFLib/rdflib/pull/1686 inadvertently removed the wgs prefix. This change adds it back.

fix: change the prefix for https://schema.org/ back to schema (#2312)

Commit 3faa01b, closes #2312.

The default prefix for https://schema.org/ registered with rdflib.namespace.NamespaceManager was inadvertently changed to sdo in 6.2.0, this however constitutes a breaking change, as code that was using the schema prefix would no longer have the same behaviour. This change changes the prefix back to schema.

fix: include docs and examples in the sdist tarball (#2289)

Commit 394fb50, closes #2289.

The sdists generated by setuptools included the docs and examples directories, and they are needed for building docs and running tests using the sdist.

This change includes these directories in the sdist tarball.

A test:sdist task is also added to Taskfile.yml which uses the sdists to run pytest and build docs.

fix: IRI to URI conversion (#2304)

Commit dfa4054, closes #2304.

The URI to IRI conversion was percentage-quoting characters that should not have been quoted, like equals in the query string. It was also not quoting things that should have been quoted, like the username and password components of a URI.

This change improves the conversion by only quoting characters that are not allowed in specific parts of the URI and quoting previously unquoted components. The safe characters for each segment are taken from RFC3986.

The new behavior is heavily inspired by

werkzeug.urls.iri_to_uri though there are some differences.

fix: JSON-LD context construction from a dict (#2306)

Commit 832e693, closes #2306.

A variable was only being initialized for string-valued inputs, but if a dict input was passed the variable would still be accessed, resulting in a UnboundLocalError.

This change initializes the variable always, instead of only when string-valued input is used to construct a JSON-LD context.

fix: reference to global inside get_target_namespace_elements (#2311)

Commit 4da67f9, closes #2311.

get_target_namespace_elements references the args global, which is not defined if the function is called from outside the module. This commit fixes that instead referencing the argument passed to the function.

fix: restore the 6.1.1 default bound namespaces (#2313)

Commit 57bb428, closes #2313.

The namespaces bound by default by rdflib.graph.Graph and rdflib.namespace.NamespaceManager was reduced in version 6.2.0 of RDFLib, however, this also would cause code that worked with 6.1.1 to break, so this constituted a breaking change. This change restores the previous behaviour, binding the same namespaces as was bound in 6.1.1.

To bind a reduced set of namespaces, the bind_namespaces parameter of rdflib.graph.Graph or rdflib.namespace.NamespaceManager can be used.

test: add webtest marker to tests that use the internet (#2295)

Commit cfe6e37, closes #2295.

This is being done so that it is easier for downstream packagers to run the test suite without requiring internet access.

To run only tests that does not use the internet, run pytest -m "not webtest".

The validation workflow validates that test run without internet access by running the tests inside firejail --net=none.

chore: Update CONTRIBUTORS from commit history (#2305)

Commit 1ab4fc0, closes #2305.

This ensures contributors are credited. Also added .mailmap to fix early misattributed contributions.

docs: fix typo in NamespaceManager documentation (#2291)

Commit 7a05c15, closes #2291.

Changed cdterms to dcterms, see https://github.com/RDFLib/rdflib/issues/2196 for more info.

2023-03-18 RELEASE 6.3.1

This is a patch release that includes a singular user facing fix, which is the inclusion of the test directory in the sdist release artifact.

The following sections describe the changes included in this version.

build: explicitly specify packages in pyproject.toml (#2280)

Commit 334787b, closes #2280.

The default behaviour makes it more of a hassle to republish RDFLib to a separate package, something which I plan to do for testing purposes and possibly other reasons.

More changes may follow in a similar vein.

build: include test in sdist (#2282)

Commit e3884b7, closes #2282.

A perhaps minor regression from earlier versions is that the sdist does not include the test folder, which makes it harder for downstreams to use a single source of truth to build and test a reliable package. This restores the test folder for sdists.

docs: don’t use kroki (#2284)

Commit bea782f, closes #2284.

The Kroki server is currently experiencing some issues which breaks our build, this change eliminates the use of Kroki in favour of directly using the generated SVG images which is checked into git alongside the PlantUML sources.

I also added a task to the Taskfile to re-generate the SVG images from the PlantUML sources by calling docker.

2023-03-16 RELEASE 6.3.0

This is a minor release that includes bug fixes and features.

Important Information

  • RDFLib will drop support for Python 3.7 when it becomes EOL on 2023-06-27, this will not be considered a breaking change, and RDFLib’s major version number will not be changed solely on the basis of Python 3.7 support being dropped.

User facing changes

This section lists changes that have a potential impact on users of RDFLib, changes with no user impact are not included in this section.

  • Add chunk serializer that facilitates the encoding of a graph into multiple N-Triples encoded chunks. PR #1968.

  • Fixes passing NamespaceManager in ConjunctiveGraph’s method get_context(). The get_context() method will now pass the NamespaceManager of ConjunctiveGraph to the namespace_manager attribute of the newly created context graph, instead of the ConjunctiveGraph object itself. This cleans up an old FIXME comment. PR #2073.

  • InfixOWL fixes and cleanup. Closed issue #2030. PR #2024, and PR #2033.

    • rdflib.extras.infixowl.Restriction.__init__ will now raise a ValueError if there is no restriction value instead of an AssertionError.

    • Fixed numerous issues with rdflib.extras.infixowl.Restriction.restrictionKind which was essentially not working at all.

    • Fixed how rdflib.extras.infixowl.Property.__repr__ uses rdflib.namespace.OWL.

    • Removed rdflib.extras.infixowl.Infix.__ror__ and rdflib.extras.infixowl.Infix.__or__ as they were broken.

    • Removed unused rdflib.extras.infixowl.termDeletionDecorator.

    • Added rdflib.extras.infixowl.MalformedClassError which will replace rdflib.extras.infixowl.MalformedClass (which is an exception) in the next major version.

    • Eliminated the use of mutable data structures in some argument defaults.

  • Fixed some cross-referencing issues in RDFLib documentation. Closed issue #1878. PR #2036.

  • Fixed import of xml.sax.handler in rdflib.plugins.parsers.trix so that it no longer tries to import it from xml.sax.saxutils. PR #2041.

  • Removed a pre python 3.5 regex related workaround in the REPLACE SPARQL function. PR #2042.

  • Fixed some issues with SPARQL XML result parsing that caused problems with lxml. Closed issue #2035, issue #1847. PR #2044.

    • Result parsing from TextIO streams now work correctly with lxml installed and with XML documents that are not utf-8 encoded.

    • Elements inside <results> that are not <result> are now ignored.

    • Elements inside <result> that are not <binding> are now ignored.

    • Also added type hints to rdflib.plugins.sparql.results.xmlresults.

  • Added type hints to the following modules:

  • Removed pre python 3.7 compatibility code. PR #2066.

    • Removed fallback in case the shutil module does not have the move function.

  • Improve file-URI and path handling in Graph.serialize and Result.serialize to address problems with windows path handling in Result.serialize and to make the behavior between Graph.serialize and Result.serialie more consistent. Closed issue #2067. PR #2065.

    • String values for the destination argument will now only be treated as file URIs if urllib.parse.urlparse returns their schema as file.

    • Simplified file writing to avoid a temporary file.

  • Narrow the type of context-identifiers/graph-names from rdflib.term.Node to rdflib.term.IdentifiedNode as no supported abstract syntax allows for other types of context-identifiers. PR #2069.

  • Always parse HexTuple files as utf-8. PR #2070.

  • Fixed handling of Literal datatype to correctly differentiate between blank string values and undefined values, also changed the datatype of rdflib.term.Literal.datatype from Optional[str] to Optional[URIRef] now that all non-URIRef str values will be converted to URIRef. PR #2076.

  • Fixed the generation of VALUES block for federated queries. The values block was including non-variable values like BNodes which resulted in invalid queries. Closed issue #2079. PR #2084.

  • Only register the rdflib.plugins.stores.berkeleydb.BerkeleyDB as a store plugin if the berkeleydb module is present. Closed issue #1816. PR #2096.

  • Fixed serialization of BNodes in TriG. The TriG serializer was only considering BNode references inside a single graph and not counting the BNodes subjects as references when considering if a BNode should be serialized as unlabeled blank nodes (i.e. [ ]), and as a result it was serializing BNodes as unlabeled if they were in fact referencing BNodes in other graphs. PR #2085.

  • Deprecated rdflib.path.evalPath in favor of rdflib.path.eval_path which is PEP-8 compliant. PR #2046

  • Added charset=UTF-8 to the Content-Type header sent when doing an update with SPARQLConnector. Closed issue #2095. PR #2112.

  • Removed the rdflib.plugins.sparql.parserutils.plist class as it served no discernible purpose. PR #2143

  • Changed the TriG serializer to not generate prefixes for empty graph IDs. Closed issue #2154. PR #2160.

  • Fixed handling of relative context files in the JSON-LD parser. Closed issue #2164. PR #2165.

  • Improved failure handling in when computing QName for an unbound namespace. PR #2169.

  • Fixed a typo in the default bound namespace for DCTERMS. PR #2173.

  • Add support for supplying a custom namespace manager to n3() methods. PR #2174.

  • Fixed the query string parameters for SPARQLConnector when using POST method. PR #2180.

  • Fixed extra keyword argument and header handling in SPARQLConnector that resulted in headers from SPARQLConnector.update polluting headers from SPARQLConnector.query vice versa. PR #2183

  • Added version restrictions for dependencies. PR #2187

  • Switch to using importlib for getting the version of RDFLib instead of hard-coding it in __version__. PR #2187.

  • Removed non-runtime extras, for building documentation, running tests and other development operations the versions and dependencies are now managed with Poetry. PR #2187.

  • Fixed a bug that occurred when VALUES was used outside a GROUP BY clause. PR #2188.

  • Fixed a bug that occurred when using SELECT * inside another SELECT *. Closed issue #1722. PR #2190.

  • Added SPARQL DESCRIBE query implementation. Closes issue #479. PR #2221.

  • Fixed a bug in rdflib.tools.defined_namespace_creator that occurred when multiple rdfs:comment were present on one resource. PR #2254.

  • Fixed rdflib.util._iri2uri() to not quote the netloc parameter. PR #2255.

  • Fixed the HexTuple parser’s handling of input sources to works for more input sources. PR #2255.

  • Fixed the creation of input source objects from IO stream sources. PR #2255.

2022-07-16 RELEASE 6.2.0

This is a minor release that includes bug fixes and features.

User facing changes

This section lists changes that have a potential impact on users of RDFLib, changes with no user impact are not included in this section.

  • SPARQL: Fixed handing of HAVING clause with variable composition. Closed issue #936 and issue #935, PR #1093.

  • JSON-LD parser: better support for content negotiation. Closed issue #1423, PR #1436.

  • Removed the following functions that were marked as deprecated and scheduled for removal in version 6.0.0: Graph.load, Graph.seq, Graph.comment, Graph.label. PR #1527.

  • Use functools.total_ordering to implement most comparison operations for rdflib.paths.Path. Closed issue #685, PR #1528.

  • Fixed error handling for invalid URIs. Closed issue #821, PR #1529.

  • InfixOWL: Fixed handling of cardinality 0. Closed issue #1453 and issue #944, PR #1530.

  • Added quad support to handling to rdflib.graph.ReadOnlyGraphAggregate.quads. Closed issue #430, PR #1590

  • Fixed base validation used when joining URIs. PR #1607.

  • Add GEO defined namespace for GeoSPARQL. Closed issue #1371, PR #1622.

  • Explicitly raise exception when rdflib.plugins.stores.sparqlstore.SPARQLStore.update is called. Closed issue #1032, PR #1623.

  • Added rdflib.plugins.sparql.processor.prepareUpdate. Closed issue #272 and discussion #1581, PR #1624.

  • Added rdflib.namespace.DefinedNamespaceMeta.__dir__. Closed issue #1593, PR #1626.

  • Removed TypeCheckError, SubjectTypeError, PredicateTypeError, ObjectTypeError and ContextTypeError as these exceptions are not raised by RDFLib and their existence will only confuse users which may expect them to be used. Also remove corresponding check_context, check_subject, check_predicate, check_object, check_statement, check_pattern that is unused. PR #1640.

  • Improved the population of the Accept HTTP header so that it is correctly populated for all formats. PR #1643.

  • Fixed some issues with SPARQL Algebra handling/translation. PR #1645.

  • Add nquads to recognized file extensions. PR #1653.

  • Fixed issues that prevented HexTuples roundtripping. PR #1656.

  • Make rdflib.plugins.sparql.operators.unregister_custom_function idempotent. Closed issue #1492, PR #1659.

  • Fixed the handling of escape sequences in the N-Triples and N-Quads parsers. These parsers will now correctly handle strings like "\\r". The time it takes for these parsers to parse strings with escape sequences will be increased, and the increase will be correlated with the amount of escape sequences that occur in a string. For strings with many escape sequences the parsing speed seems to be almost 4 times slower. Closed issue #1655, PR #1663.

    • Also marked rdflib.compat.decodeStringEscape as deprecated as this function is not used anywhere in RDFLib anymore and the utility that it does provide is not implemented correctly. It will be removed in RDFLib 7.0.0

  • Added an abstract class IdentifiedNode as a superclass of BNode and URIRef. Closed issue #1526, PR #1680.

  • Fixed turtle serialization of rdf:type in subject, object. Closed issue #1649, PR #1649.

  • Fixed turtle serialization of PNames that contain brackets. Closed issue #1661, PR #1678.

  • Added support for selecting which namespace prefixes to bind. Closed issue #1679 and issue #1880, PR #1686, PR #1845 and PR #2018.

    • Also added ConjunctiveGraph.get_graph.

    • Also added an override argument to Store.bind which behaves similarly to the override parameter for NamespaceManager.bind.

    • Also fixed handing of support of the override parameter to NamespaceManager.bind by passing.

  • Eliminated a DeprecationWarning related to plugin loading issue #1631, PR #1694.

  • Removed the rdflib.graph.ContextNode and rdflib.graph.DatasetQuad type aliases. These were not being widely used in RDFLib and were also not correct. PR #1695.

  • Added DefinedNamespace.as_jsonld_context. PR #1706.

  • Added rdflib.namespace.WGS for WGS84. Closed issue #1709, PR #1710.

  • Improved performance of DefinedNamespace by caching attribute values. PR #1718.

  • Only configure python logging if sys.stderr has a isatty attribute. Closed issue #1760, PR #1761.

  • Removed unused rdflib.compat.etree_register_namespace. PR #1768.

  • Fixed numeric shortcut handling in rdflib.util.from_n3. Closed issue #1769, PR #1771.

  • Add ability to detect and mark ill-typed literals. Closed issue #1757 and issue #848, PR #1773 and PR #2003.

  • Optimized NamespaceManager.compute_qname by caching validity. PR #1779.

  • SPARQL: Fixed the handling of EXISTS inside BIND for SPARQL. This was raising an exception during evaluation before but is now correctly handled. Closed issue #1472, PR #1794.

  • Propagate exceptions from SPARQL TSV result parser. Closed issue #1477, PR #1809

  • Eliminate usage of rdflib.term.RDFLibGenid as a type as this caused issues with querying. Closed issue #1808, PR #1821

  • Fixed handing of DefinedNamespace control attributes so that inspect.signature works correctly on defined namespaces. PR #1825.

  • Fixed namespace rebinding in Memory, SimpleMemory and BerkelyDB stores. Closed issue #1826, PR #1843.

  • Fixed issues with the N3 serializer. Closed issue #1701 and issue #1807, PR #1858:

    • The N3 serializer was incorrectly considers a subject as seralized if it is serialized in a quoted graph.

    • The N3 serializer does not consider that the predicate of a triple can also be a graph.

  • Added NamespaceManager.expand_curie. Closed issue #1868, PR #1869.

  • Added Literal.__sub__ and support for datetimes to both Literal.__add__ and Literal.__sub__. PR #1870.

  • SPARQL: Fix None/undefined handing in GROUP_CONCAT. Closed issue #1467, PR #1887.

  • SPARQL: Fixed result handling for SERVICE directive. Closed issue #1278, PR #1894.

  • Change the skolem default authority for RDFLib from http://rdlib.net/ to https://rdflib.github.io and also change other uses of http://rdlib.net/ to https://rdflib.github.io. Closed issue #1824, PR #1901.

  • Fixes handling of non-ascii characters in IRIs. Closed issue #1429, PR #1902.

  • Pass generate to NamespaceManager.compute_qname from NamespaceManager.compute_qname_strict so it raises an error in the same case as the “non-strict” version. PR #1934.

  • Log warnings when encountering ill-typed literals. PR #1944.

  • Fixed error handling in TriX serializer. PR #1945.

  • Fixed QName generation in XML serializer. PR #1951

  • Remove unnecessary hex expansion for PN_LOCAL in SPARQL parser. Closed issue #1957, PR #1959.

  • Changed the TriX parser to support both trix and TriX as root element. PR #1966.

  • Fix SPARQL CSV result serialization of blank nodes. PR #1979.

  • Added a URIRef.fragment property. PR #1991.

  • Remove superfluous newline from N-Triples output. Closed issue #1998, PR #1999.

  • Added a bunch of type hints. The following modules have nearly complete type hints now:

    • rdflib.namespace

    • rdflib.term

    • rdflib.parser

2021-07-20 RELEASE 6.0.0

6.0.0 is a major stable release that drops support for Python 2 and Python 3 < 3.7. Type hinting is now present in much of the toolkit as a result.

It includes the formerly independent JSON-LD parser/serializer, improvements to Namespaces that allow for IDE namespace prompting, simplified use of g.serialize() (turtle default, no need to decode()) and many other updates to documentation, store backends and so on.

Performance of the in-memory store has also improved since Python 3.6 dictionary improvements.

There are numerous supplementary improvements to the toolkit too, such as:

  • inclusion of Docker files for easier CI/CD

  • black config files for standardised code formatting

  • improved testing with mock SPARQL stores, rather than a reliance on DBPedia etc

  • Graph comparison now really works using RGDA1 (RDF Graph Digest Algorithm 1) #441 #385

  • More graceful degradation than simple crashing for unicode chars > 0xFFFF on narrow python builds. Parsing such characters will now work, but issue a UnicodeWarning. If you run python -W all you will already see a warning on import rdflib will show a warning (ImportWarning). #453, #454

  • RDF/XML Serializer now uses parseType=Literal for well-formed XML literals

  • A bug in the manchester OWL syntax was fixed #355

2013-12-31 RELEASE 4.1

This is a new minor version RDFLib, which includes a handful of new features:

  • A TriG parser was added (we already had a serializer) - it is up-to-date wrt. to the newest spec from: http://www.w3.org/TR/trig/

  • The Turtle parser was made up to date wrt. to the latest Turtle spec.

  • Many more tests have been added - RDFLib now has over 2000 (passing!) tests. This is mainly thanks to the NT, Turtle, TriG, NQuads and SPARQL test-suites from W3C. This also included many fixes to the nt and nquad parsers.

  • ConjunctiveGraph and Dataset now support directly adding/removing quads with add/addN/remove methods.

  • rdfpipe command now supports datasets, and reading/writing context sensitive formats.

  • Optional graph-tracking was added to the Store interface, allowing empty graphs to be tracked for Datasets. The DataSet class also saw a general clean-up, see: #309

  • After long deprecation, BackwardCompatibleGraph was removed.

Minor enhancements/bugs fixed:

  • Many code samples in the documentation were fixed thanks to @PuckCh

  • The new IOMemory store was optimised a bit

  • SPARQL(Update)Store has been made more generic.

  • MD5 sums were never reinitialized in rdflib.compare

  • Correct default value for empty prefix in N3 #312

  • Fixed tests when running in a non UTF-8 locale #344

  • Prefix in the original turtle have an impact on SPARQL query resolution #313

  • Duplicate BNode IDs from N3 Parser #305

  • Use QNames for TriG graph names #330

  • \uXXXX escapes in Turtle/N3 were fixed #335

  • A way to limit the number of triples retrieved from the SPARQLStore was added #346

  • Dots in localnames in Turtle #345 #336

  • BNode as Graph’s public ID #300

  • Introduced ordering of QuotedGraphs #291

2013-05-22 RELEASE 4.0.1

Following RDFLib tradition, some bugs snuck into the 4.0 release. This is a bug-fixing release:

  • the new URI validation caused lots of problems, but is necessary to avoid ‘’RDF injection’’ vulnerabilities. In the spirit of ‘’be liberal in what you accept, but conservative in what you produce”, we moved validation to serialisation time.

  • the rdflib.tools package was missing from the setup.py script, and was therefore not included in the PYPI tarballs.

  • RDF parser choked on empty namespace URI #288

  • Parsing from sys.stdin was broken #285

  • The new IO store had problems with concurrent modifications if several graphs used the same store #286

  • Moved HTML5Lib dependency to the recently released 1.0b1 which support python3

2013-05-16 RELEASE 4.0

This release includes several major changes:

  • The new SPARQL 1.1 engine (rdflib-sparql) has been included in the core distribution. SPARQL 1.1 queries and updates should work out of the box.

    • SPARQL paths are exposed as operators on URIRefs, these can then be be used with graph.triples and friends:

      from rdflib import Graph, URIRef
from rdflib.namespace import FOAF, RDFS

g = Graph()
bob = URIRef("...")
cls = URIRef("...")

# List names of friends of Bob:
g.triples((bob, FOAF.knows/FOAF.name , None))

# All super-classes:
g.triples((cls, RDFS.subClassOf * '+', None))

      • a new graph.update method will apply SPARQL update statements

  • Several RDF 1.1 features are available:

    • A new DataSet class

    • XMLLiteral and HTMLLiterals

    • BNode (de)skolemization is supported through BNode.skolemize, URIRef.de_skolemize, Graph.skolemize and Graph.de_skolemize

  • Handled of Literal equality was split into lexical comparison (for normal == operator) and value space (using new Node.eq methods). This introduces some slight backwards incompatible changes, but was necessary, as the old version had inconsistent hash and equality methods that could lead the literals not working correctly in dicts/sets. The new way is more in line with how SPARQL 1.1 works. For the full details, see:

    https://github.com/RDFLib/rdflib/wiki/Literal-reworking

  • Iterating over QueryResults will generate ResultRow objects, these allow access to variable bindings as attributes or as a dict. I.e.

    for row in g.query('select ... ') :
   print row.age, row["name"]

  • “Slicing” of Graphs and Resources as syntactic sugar: (#271)

    graph[bob : FOAF.knows/FOAF.name]
          -> generator over the names of Bobs friends

  • The SPARQLStore and SPARQLUpdateStore are now included in the RDFLib core

  • The documentation has been given a major overhaul, and examples for most features have been added.

Minor Changes:

  • String operations on URIRefs return new URIRefs: (#258)

    >>> URIRef('http://example.org/')+'test
rdflib.term.URIRef('http://example.org/test')

  • Parser/Serializer plugins are also found by mime-type, not just by plugin name: (#277)

  • Namespace is no longer a subclass of URIRef

  • URIRefs and Literal language tags are validated on construction, avoiding some “RDF-injection” issues (#266)

  • A new memory store needs much less memory when loading large graphs (#268)

  • Turtle/N3 serializer now supports the base keyword correctly (#248)

  • py2exe support was fixed (#257)

  • Several bugs in the TriG serializer were fixed

  • Several bugs in the NQuads parser were fixed

2013-03-01 RELEASE 3.4

This release introduced new parsers for structured data in HTML. In particular formats: hturtle, rdfa, mdata and an auto-detecting html format were added. Thanks to Ivan Herman for this!

This release includes a lot of admin maintentance - correct dependencies for different python versions, etc. Several py3 bugs were also fixed.

This release drops python 2.4 compatibility - it was just getting too expensive for us to maintain. It should however be compatible with any cpython from 2.5 through 3.3.

  • node.md5_term is now deprecated, if you use it let us know.

  • Literal.datatype/language are now read-only properties (#226)

  • Serializing to file fails in py3 (#249)

  • TriX serializer places two xmlns attributes on same element (#250)

  • Fixes broken querying (#234)

  • graph.transitiveClosure now works with loops (#206)

2012-09-25 RELEASE 3.2.2

This is mainly a maintenance release.

Changes:

  • Improved serialization/parsing roundtrip tests led to some fixes of obscure parser/serializer bugs. In particular complex string Literals in ntriples improved a lot.

  • The terms of a triple are now asserted to be RDFLib Node’s in graph.add This should avoid getting strings and other things in the store. (#200)

  • Added a specific TurtleParser that does not require the store to be non-formula aware. (#214)

  • A trig-serializer was added, see: http://www4.wiwiss.fu-berlin.de/bizer/trig/

  • BNode generation was made thread-safe (#209) (also fixed better by dzinxed)

Working test suite with all tests passing.

Removed dependency on setuptools.

(Issue #43) Updated Package and Module Names to follow conventions outlined in http://www.python.org/dev/peps/pep-0008/

Removed SPARQL bits and non core plugins. They are mostly moving to http://code.google.com/p/rdfextras/ at least until they are stable.

Fixed datatype for Literal(True).

Fixed Literal to enforce constraint of having either a language or datatype but not both.

Fixed Literal’s repr.

Fixed to Graph Add/Sub/Mul opterators.

Upgraded RDFa parser to pyRdfa.

Upgraded N3 parser to the one from CWM.

Fixed unicode encoding issue involving N3Parser.

N3 serializer improvements.

Fixed HTTP content-negotiation

2007-04-04 RELEASE 2.4.0

Improved Literal comparison / equality

Sparql cleanup.

getLiteralValue now returns the Literal object instead of the result of toPython(). Now that Literals override a good coverage of comparison operators, they should be passed around as first class objects in the SPARQL evaluation engine.

Added support for session bnodes re: sparql

Fixed prolog reduce/reduce conflict. Added Py_None IncRefs where they were being passed into Python method invocations (per drewp’s patch)

Fixed sparql queries involving empty namespace prefix.

Fixed the selected variables sparql issue

Fixed test_sparql_equals.py.

Fixed sparql json result comma errors issue.

Fixed test_sparql_json_results.py (SELECT * variables out of order)

The restriction on GRAPH patterns with variables has been relieved a bit to allow such usage when the variable is provided as an initial binding

Fix for OPTIONAL patterns. P1 OPT P2, where P1 and P2 shared variables which were bound to BNodes were not unifying on these BNode variable efficiently / correctly. The fix was to add bindings for ‘stored’ BNodes so they aren’t confused for wildcards

Added support to n3 parser for retaining namespace bindings.

Fixed several RDFaParser bugs.

Added serializer specific argument support.

Fixed a few PrettyXMLSerializer issues and added a max_depth option.

Added commit_pending_transaction argument to Graph’s close method.

Added DeprecationWarning to rdflib.constants

Added a NamespaceDict class for those who want to avoid the Namespace as subclass of URIRef issues

Added bind function

Fixed type of Namespace re: URIRef vs. unicode

Improved ValueError message

Changed value method’s any argument to default to True

Changed __repr__ to always reflect that it’s an rdf.Literal – as this is the case even though we now have it acting like the corresponding type in some casses

A DISTINCT was added to the SELECT clause to ensure duplicate triples are not returned (an RDF graph is a set of triples) - which can happen for certain join expressions.

Support for ConditionalAndExpressionList and RelationalExpressionList (|| and && operators in FILTER)

Fixed context column comparison. The hash integer was being compared with ‘F’ causing a warning:Warning: Truncated incorrect DOUBLE value: ‘F’

applied patch in http://rdflib.net/issues/2006/12/13/typos_in_abstractsqlstore.py/issue

fix for http://rdflib.net/issues/2006/12/07/problems_with_graph.seq()_when_sequences_contain_more_than_9_items./issue

General code cleanup (removing redundant imports, changing relative imports to absolute imports etc)

Removed usage of deprecated bits.

Added a number of test cases.

Added DeprecationWarning for save method

refactoring of GraphPattern

ReadOnlyGraphAggregate uses Graph constructor properly to setup (optionally) a common store

Fixed bug with . (fullstop) in localname parts.

Changed Graph’s value method to return None instead of raising an AssertionError.

Fixed conversion of (exiplicit) MySQL ports to integers.

Fixed MySQL store so it properly calculates __len__ of individual Graphs

Aligned with how BerkeleyDB is generating events (remove events are expressed in terms of interned strings)

Added code to catch unpickling related exceptions

Added BerkeleyDB store implementation.

Merged TextIndex from michel-events branch.

Changed Literal and URIRef instantiation to catch UnicodeDecodeErrors - which were being thrown when the default decoding method (ascii) was hitting certain characters.

Changed Graph’s bind method to also override the binding in the case of an existing generated bindings.

Added FOPLRelationalModel - a set of utility classes that implement a minimal Relational Model of FOPL implemented as a SQL database (uses identifier/value interning and integer half-md5-hashes for space and index efficiency).

Changed MySQL store to use FOPLRelationalModel plus fixes and improvements.

Added more test cases.

Cleaned up source code to follow pep8 / pep257.

2006-02-27 RELEASE 2.3.1

2005-12-23 RELEASE 2.3.0

See http://rdflib.net/2.3.0/ for most up-to-date release notes

Added N3 support to Graph and Store.

Added Sean’s n3p parser, and ntriples parser.

BerkeleyDB implementation has been revamped in the process of expanding it to support the new requirements n3 requirements. It also now persists a journal – more to come.

detabified source files.

Literal and parsers now distinguish between datatype of None and datatype of “”.

Store-agnostic ‘fallback’ implementation of REGEX matching (inefficient but provides the capability to stores that don’t support it natively). Implemented as a ‘wrapper’ around any Store which replaces REGEX terms with None (before dispatching to the store) and whittles out results that don’t match the given REGEX term expression(s).

Store-agnostic ‘fallback’ implementation of transactional rollbacks (also inefficient but provides the capability to stores that don’t support it natively). Implemented as a wrapper that tracks a ‘thread-safe’ list of reversal operations (for every add, track the remove call that reverts the store, and vice versa). Upon store.rollback(), execute the reverse operations. However, this doesn’t guarantee durability, since if the system fails before the rollbacks are all executed, the store will remain in an invalid state, but it provides Atomicity in the best case scenario.
