Use
---
You can use these stores like this:
.. code-block:: python
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:
.. code-block:: python
from rdflib import Graph
# use the BerkeleyDB Store
graph = Graph(store="BerkeleyDB")
graph.open("/some/folder/location")
# do things ...
graph.close()
