Three Recommendations were published today to enhance data interoperability, especially in government data. Each one specifies an RDF vocabulary (a set of properties and classes) for conveying a particular kind of information:

• The Data Catalog (DCAT) Vocabulary is used to provide information about available data sources. When data sources are described using DCAT, it becomes much easier to create high-quality integrated and customized catalogs including entries from many different providers. Many national data portals are already using DCAT.
• The Data Cube Vocabulary brings the cube model underlying SDMX (Statistical Data and Metadata eXchange, a popular ISO standard) to Linked Data. This vocabulary enables statistical and other regular data, such as measurements, to be published and then integrated and analyzed with RDF-based tools.
• The Organization Ontology provides a powerful and flexible vocabulary for expressing the official relationships and roles within an organization. This allows for interoperation of personnel tools and will support emerging socially-aware software.

All three vocabularies have been developed by the Government Linked Data Working Group, but they are applicable beyond just government data. For a list of data sources or software known to be using these vocabularies, see the “Implementation Report” linked from each document. Learn more about the Data Activity.
