ramm.x relies heavily on W3C's RDFa technology, an open Web standard that can be freely used by anyone.

RDF Resource Description Framework Metadata Icon

To obtain the metadata of this specification, follow the RDFa extractor link, a service provided by Dave Beckett.

The visual layout and structure of this specification was adapted from the FOAF Vocabulary Specification by Dan Brickley and Libby Miller,
and the SIOC Core Ontology Specification by Uldis Bojars and John G. Breslin, respectively.


The RDFa-deployed Multimedia Metadata (ramm.x) specification provides a framework for deploying multimedia metadata on the Semantic Web. To keep the ramm.x core specification as light-weight, hence implementable as possible, so called extensions are defined in this document.
