The Resource Description Framework is slowly becoming a new standard for data interchange – among its key features there are certainly the simplicity of its model, but yet a powerful mechanism for encoding knowledge at any level of abstraction/complexity. Some of its most famous applications include:

  • RDF Site Summary – one of several “RSS” languages for publishing information about updates made to a web page; it is often used for disseminating news article summaries and sharing weblog content.
  • FOAF (Friend of a Friend) – designed to describe people, their interests and interconnections.
  • DOAC (Description of a Career) – supplements FOAF to allow the sharing of résumé information.
  • DOAP (Description of a Project) – designed to describe software projects; uses FOAF to identify the people involved
  • SIOC (Semantically-Interlinked Online Communities) – designed to describe online communities and to create connections between Internet-based discussions from message boards, weblogs and mailing lists. 
  • MusicBrainz – Publishes information about Music Albums. 
  • Creative Commons – Uses RDF to embed license information in web pages and mp3 files.

Being a fundamental issue for Cohere the import/export of data, we very soon decided to provide support for the RDF format as well. Here’s some of the services we plan to make available: 

  • extending the APIs for exporting RDF’ized Cohere data
  • let users import large quantities of data formatted using the RDF Cohere schema
  • import/export of AIF-RDF data

So, for the moment, we formalized the Cohere data model using OWL – this is the schema you will have to use so to be able to import your files. The Cohere ontology can be accessed at Open it with ProtegeGrowl or your preferred ontology editor. There is also some documentation available here. And for all the rest, stay tuned!
