The Dublin Core (named for Dublin, Ohio, where the first workshop in the effort was held) has established suggestions for metadata about online resources.
The Resource Description Framework (RDF) integrates a variety of applications from library catalogs and world-wide directories to syndication and aggregation of news, software, and content to personal collections of music, photos, and events using XML as an interchange syntax. The RDF specifications provide a lightweight ontology system to support the exchange of knowledge on the Web.
