EBNF is a Ruby parser for W3C EBNF and a parser generator for PEG and LL(1). Also includes parsing modes for ISO EBNF and ABNF.

SPARQL Implements SPARQL 1.1 Query, Update and result formats for the Ruby RDF.rb library suite.

Spira is a framework for using the information in RDF.rb repositories as model objects.

A metadistribution of RDF.rb including a full set of parsing/serialization plugins.

RDF::RDFa is an RDFa reader/writer for Ruby using the RDF.rb library suite.

RDF::Turtle is an Turtle reader/writer for the RDF.rb library suite.

Reads HTML Microdata as RDF.

RDF::N3 is an Notation-3 reader/writer and reasoner for the RDF.rb library suite.

RDF::Normalize performs Dataset Canonicalization for RDF.rb.

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.

RDF.rb plugin providing a Sesame 2.0 storage adapter.
