We reported yesterday on the news that JSON-LD has reached Recommendation status at W3C. Three formal vocabularies also reached that important milestone yesterday:
The W3C Documentation for The Data Catalog Vocabulary (DCAT), says that DCAT "is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web....By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of catalogs and facilitates federated dataset search across sites. Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation."
Meanwhile, The RDF Data Cube Vocabulary addresses the following issue: "There are many situations where it would be useful to be able to publish multi-dimensional data, such as statistics, on the web in such a way that it can be linked to related data sets and concepts. The Data Cube vocabulary provides a means to do this using the W3C RDF (Resource Description Framework) standard. The model underpinning the Data Cube vocabulary is compatible with the cube model that underlies SDMX (Statistical Data and Metadata eXchange), an ISO standard for exchanging and sharing statistical data and metadata among organizations. The Data Cube vocabulary is a core foundation which supports extension vocabularies to enable publication of other aspects of statistical data flows or other multidimensional data sets."
Lastly, W3C now recommends use of the Organization Ontology, "a core ontology for organizational structures, aimed at supporting linked data publishing of organizational information across a number of domains. It is designed to allow domain-specific extensions to add classification of organizations and roles, as well as extensions to support neighbouring information such as organizational activities."
