Convert BEL 2.0 to RDF (bel.rb)

[abargnesi]

Motivation

The RDF translator plugin in bel.rb will convert BEL 1.0. to RDF. These conversions are implemented using Open Class (i.e. monkey patching) in lib/bel/translator/plugins/rdf/monkey_patch.rb.

This work is to provide a conversion from BEL 2.0 Nanopubs to BEL RDF 2.0.

Tasks

• Refactor/Fix BEL 1.0 conversion based on two things:
  • Changes made by @wshayes (see https://github.com/OpenBEL/language/blob/master/rdf-schema/belRdfSchema-1.0.ttl)
  • The monkey patch design is clunky, hard to test, and not conducive to switching language implementations. The BEL 1.0 implementation should be changed to separate set of function-oriented conversion routes (e.g map function to convert Parameter object to Array of RDF statements).
• Implement conversion from BEL 2.0 Nanopubs to BEL RDF 2.0.
• Choose the RDF converter based on the input language specification (BEL 1.0 -> BEL RDF 1.0, BEL 2.0 -> BEL RDF 2.0).
