- Friend-of-a-Friend (FOAF), vocabulary for describing people.
- Dublin Core (DC) defines general metadata attributes. See also their new domains and ranges draft.
- Semantically-Interlinked Online Communities (SIOC), vocabulary for representing online communities.
- Description of a Project (DOAP), vocabulary for describing projects.
- Simple Knowledge Organization System (SKOS), vocabulary for representing taxonomies and loosely structured knowledge.
- Music Ontology provides terms for describing artists, albums and tracks.
- Review Vocabulary, vocabulary for representing reviews.
- Creative Commons (CC), vocabulary for describing license terms.
- The URIs are dereferenceable, meaning that a description of the concept can be retrieved from the Web. For instance, using the DBpedia URI http://dbpedia.org/page/Doom to identify the computer game Doom gives you an extensive description of the game including abstracts in 10 different languages and various classifications.
- The URIs are already linked to URIs from other data sources. For instance, you can navigate from the DBpedia URI http://dbpedia.org/resource/Berlin to data about Berlin provided by Geonames and EuroStat. Therefore, by using concept URIs form these datasets, you interlink your data with a rich and fast-growing network of other data sources.
4.1 Reusing existing terms
A set of well-known vocabularies has evolved in the Semantic Web community. Please check whether your data can be represented using terms from these vocabularies before defining any new terms:
A more extensive list of well-known vocabularies is maintained by the W3C SWEO Linking Open Data community project in the ESW Wiki. A listing of the 100 most common RDF namespaces (August 2006) is provided by UMBC eBiquity Group.
It is common practice to mix terms from different vocabularies. We especially recommend the use of rdfs:label and foaf:depiction properties whenever possible as these terms are well-supported by client applications.
If you need URI references for geographic places, research areas, general topics, artists, books or CDs, you should consider using URIs from data sources within the W3C SWEO Linking Open Data community project, for instance Geonames, DBpedia, Musicbrainz, dbtune or the RDF Book Mashup. The two main benefits of using URIs from these data sources are:
A more extensive list of datasets with dereferenceable URIs is maintained by the Linking Open Data community project in the ESW Wiki.
Good examples of how terms from different well-known vocabularies are mixed in one document and how existing concept URIs are reused are given by the FOAF profiles of Tim Berners-Lee and Ivan Herman.
