Use

You can use these stores like this:

from rdflib import Graph

# use the default memory Store
graph = Graph()

# use the BerkeleyDB Store
graph = Graph(store="BerkeleyDB")

In some cases, you must explicitly open and close a store, for example:

from rdflib import Graph

# use the BerkeleyDB Store
graph = Graph(store="BerkeleyDB")
graph.open("/some/folder/location")
# do things ...
graph.close()
