replace GreenTurtle parser with N3 #281

Open smurp opened 5 years ago

smurp commented 5 years ago

The GreenTurtle TTL parser is no longer maintained and is likely slower than N3. Furthermore N3 has broader syntax support (TriG, N3) and uses interfaces which are compatible with other libraries, so converting to it (which would be a slight pain) will have dividends down the road. It even has an in-RAM datastore option. There is a compatible IndexedDB store which is compatible as well, IIRC.

This is a high priority because:

there is legal Turtle which the GreenTurtle does not recognize
... meaning that there are ontologies which HuViz can't process because GreenTurtle can't parse them (eg VoID)
GreenTurtle is no longer maintained
N3 is strongly supported
N3 has a deep test suite
N3 has APIs which are being used in other projects (caches; LDF; etc)
N3 is very fast
N3 can parse streams

Complexities

This task might depend on modernization of our build procedures: https://github.com/cwrc/HuViz/issues/296
