Simplify installation for alpha0.5

[slarson]

As reported on the openworm-discuss list folks are running into roadblocks installing this library due to a dependency on the BerkeleyDB being installed on their system and version mismatches. This is too high a bar for most users to have to worry about; they won't use this and they'll go elsewhere. We need to simplify the installation procedures so that pip install is really all that is needed.

One approach may be to look at adding a new RDFLib backend that is pure python. Some options include:

• BlitzDB
• Codernity
• BuzHug

Looks like ZODB may be an out of the box easy-to-install solution as it already has an RDFLib backend. Then again it seems to have some incompatibilities that may be problematic.

We don't need to worry about the binary dependencies if we rely on a simple
RDF serialization. Loading in the database once on install isn't
problematic.

@mwatts15 any update on this one?

Unit tests pass with rdflib-zodb. It seems to need additional configuration to store the DB in a file.

[slarson]

is that checked in somewhere now? not seeing any references to zodb in the
last two commits from you.

No, I tested it locally.

ok-- since we're operating on limited time, if you want to commit to your
personal repo fork and have me review just let me know.

If you want to have a look, I pushed a branch zodb.
