ObjectDB
- persistent SQL graph store
- space efficient for scalability
each string and URL appears only once (atomic)
- optimized for bulk transfer
well, that was the intent anyways
- aboutEach assertion implemented with a generic mapped statement mechanism
- each member of theBag has an address -> (has (rdf:li #theBag *) address)
- lasts beyond scope of current document
- not limited to aboutEach - RDF grammers may use it for their own devious purposes
