The Semantic Web’s Rocking, And There Ain’t No Stopping It Now

archerMake no mistake about it: The semantic web has been a success and that’s not about to stop now. That was essentially the message delivered by W3C Data Activity Lead Phil Archer, during his keynote address celebrating the semantic web’s ten years of achievement at last month’s Semantic Technology & Business Conference in San Jose.

After acknowledging that he’s heard it all about the semantic web being a failure, about it being rebranded as Linked Data and that being a failure too, he summed up those impressions in one distinctly British word: “Bollocks.” The list of successes ranged across the spectrum, from the use in federated data portals of the Data Catalog Vocabulary from the W3C’s Government Linked Data Working Group, to the 47-million triples strong Open Phacts pharmacology discovery platform, to all the job postings that come up on The Semantic Web Blog – including one recently for the J. Craig Venter Institute, named for the pioneer genomic researcher who sequenced the human genome, which is looking for a bioinformatics analyst with OWL expertise in his or her resume.

That’s just a taste of the many citations he offered of the semantic web’s successes to date, not least among them his own strong familiarity with Linked Data’s use in government, where the technologies, he said, are used “to make our government more efficient” by having one organization make an authoritative data set the others can link to to support data-sharing across agencies.

New Vocabularies Are Now W3C Recommendations

W3C LogoWe 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.”
