Naming Properties and Relations is a Semantic Webby post from Jeni Tennison.
This post is about how to name properties and relations in RDF schemas. Or rather, about how different ontology developers use different conventions and how this can sometimes be confusing.
… We’re making an explicit distinction within the service between the idea of an item or section of legislation (such as the Criminal Justice Act 1993 Section 67), versions of that legislation (such as the Criminal Justice Act 1993 Section 67 as it was in force on 1st December 2001) and that version formatted in XML, HTML or some other format (such as the XML version of the Criminal Justice Act 1993 Section 67 as it was in force on 1st December 2001).
These three ways of thinking about legislation correspond to the FRBR Work, Expression and Manifestation. So to talk about them in RDF, we use the FRBR vocabulary created by Ian Davis and Richard Newman, in which these classes are called frbr:Work, frbr:Expression and frbr:Manifestation.
Ian Davis left a clarifying comment about his RDF schema, too.
