Callimachus is a Semantic Web framework for easily building hyperlinked Web applications. Callimachus allows Web authors to quickly and easily create Semantically-enabled Web applications with a minimal knowledge of Semantic Web principles.

Callimachus builds on either Sesame or Mulgara for RDF storage, AliBaba (a RESTful object-RDF library) and uses a revolutionary template-by-example technique for viewing and editing resources.

Callimachus uses RDFa as a query language; templates are parsed to build SPARQL from RDFa markup and then filled with query results.
