It’s taken a while but we’ve finally been able to launch the RDF Data Shapes Working Group. As the charter for the new WG says, the mission is to produce a language for defining structural constraints on RDF graphs. In the same way that SPARQL made it possible to query RDF data, the product of […]

Vocabularies at W3C

In my opening post on this blog I hinted that another would follow concerning vocabularies. Here it is. When the Semantic Web first began, the expectation was that people would create their own vocabularies/schemas as required – it was all part of the open world (free love, do what you feel, dude) Zeitgeist. Over time, […]

Three Vocabularies Are Proposed Recommendations

The Government Linked Data Working Group has published three Proposed Recommendations. The Data Catalog Vocabulary (DCAT), an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable […]
