RDF.rb <-> RdfContext mapping (work-in-progress)

RDF.rb === RdfContext

This is a quick overview and mapping between RDF.rb and RdfContext, two RDF libraries for Ruby, to serve as an aid in determining whether the projects would benefit from aligning goals and direction.

• http://github.com/gkellogg/rdf_context

An experimental fork of RdfContext that attempts some integration between the two object models:

General Notes

• RDF.rb draws on Sesame's design, RdfContext on RDFLib's; hence e.g. some differences in naming.
• RDF.rb's focus is primarily on the object model and interfaces, RdfContext's on supporting the most important serialization formats.
• RDF.rb tends toward minimalism, RdfContext towards full-featuredness.
