Just FYI the core features of rdflib.js

- Reads and writes RDF/xml, turtle and N3.
- Read/Write Linked Data client, using WebDav or SPARQL/Update
- Parses RDF/a. (rdflib-rdfa.js version only)
- Local API for querying store
- SPARQL queries (not full SPARQL)
- Smushing of nodes from owl:sameAs, and owl:{f,inverseF}unctionProperty
- Tracks provence of triples keeps metadata (in RDF) from HTTP accesses

As well as a few other things like owl sameAs FP IFP, smushing, following
links one deep, callbacks, tracking redirects, tracking the status codes of
remote links, and indexing the store

rdflib is quite modular but doesnt (yet) handle sparql parsing or is fully
1.1 compliant ... I wonder if modular common pieces could be reused ...
