The FRBR-aligned Bibliographic Ontology is an ontology for recording and publishing on the Semantic Web bibliographic records of scholarly endeavours. It forms part of SPAR, a suite of Semantic Publishing and Referencing Ontologies.
Knoodl facilitates community-oriented development of OWL based ontologies and RDF knowledgebases. It also serves as a semantic technology platform, offering a JAVA service-based interface or a SPARQL-based interface so that communities can build their own semantic applications using their ontologies and knowledgebases.
OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.
The Bibliographic Ontology Specification provides main concepts and properties for describing citations and bibliographic references (i.e. quotes, books, articles, etc) on the Semantic Web.
