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.

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.

RDF::RDFXML is an RDF/XML reader and writer for the RDF.rb library suite.

ActiveTriples provides tools for modeling RDF as discrete resources.

A gem extending RDF.rb with SPARQL dataset construction semantics.

RDF.rb extension for graph bijections and isomorphic equivalence.

RDF.rb extension for parsing/serializing RDF/JSON data.

RDF.rb plugin for parsing/serializing NTriples, RDF/XML, Turtle and RDFa data using the Raptor RDF Parser library.

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.
