Ontology for Media Resources 1.0 W3C Recommendation 09 February 2012
From the abstract:
This document defines the Ontology for Media Resources 1.0. The term “Ontology” is used in its broadest possible definition: a core vocabulary. The intent of this vocabulary is to bridge the different descriptions of media resources, and provide a core set of descriptive properties. This document defines a core set of metadata properties for media resources, along with their mappings to elements from a set of existing metadata formats. Besides that, the document presents a Semantic Web compatible implementation of the abstract ontology using RDF/OWL. The document is mostly targeted towards media resources available on the Web, as opposed to media resources that are only accessible in local repositories.
Credit where credit is due. It is nice to see that this ontology comes with a mapping to existing metadata formats.
I would not take the last line about “media resources available on the web,” too seriously. There are more media resources off the web than on. If you find this ontology useful, use it.
