RDF for SQLite is a container gem for getting the simplest RDF-based applications off the ground. It uses quite a few modular gems and fixes a little inconsistency between RDF.rb and ActiveModel. This basically boils down to RDF.rb + ActiveModel + Spira + SQLite3 to create a pretty straightforward repository, serializer, parser, and ORM.

RDF.rb is a pure-Ruby library for working with Resource Description Framework (RDF) data.

Reasons over RDFS/OWL vocabularies to generate statements which are entailed based on base RDFS/OWL rules along with vocabulary information. It can also be used to ask specific questions, such as if a given object is consistent with the vocabulary ruleset. This can be used to implement SPARQL Entailment Regimes.

It uses RDF.rb and several RDF::Vocab, with options for caching RDF resources.
