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.”

 

TopQuadrant Launches TopBraid Enterprise Vocabulary Net 4.3

TopQuadrant

RALEIGH, N.C.–(BUSINESS WIRE)– TopQuadrant™, a leading semantic data integration company, today announced the release of version 4.3 of TopBraid Enterprise Vocabulary Net (TopBraid EVN), a web-based solution that simplifies the development and management of interconnected vocabularies. With the latest release, TopBraid EVN can now be used to edit arbitrary RDFS/OWL ontologies and acts as a powerful platform for other semantic editing environments. Read more

SemTechBiz’s Schema.org Panel: Which Way Will It Go?

Perhaps one of the most anticipated panels at next week’s Semantic Technology & Business Conference in San Francisco is the Wednesday morning session on Schema.org. Since the announcement of Schema.org just prior to last year’s SemTech Business Conference on the west coast, using the Schema.org shared vocabularies along with the microdata format to mark up web pages has been much debated, and created questions in the minds of webmasters and web search marketers along the lines of, “Which way should we go? Microdata or RDFa?”

Structured Data Gets a Lift

How can you not be intrigued by a project whose tag line is, “an elevator for your data.” DataLift, funded by France’s Agence Nationale de la Recherchenatl, is that project, and it’s developing a platform for publishing structured data as Linked Data. That platform is the elevator going up, and it’s due to have its first formal release by year’s end, says Francois Scharffe, scientific director at DataLift and also Associate professor at the Université de Montpellier 2 and researcher at LIRMM.

To bring your data – perhaps it’s information in a relational database or CSV files, for instance – up to the top floor, so to speak, requires making four stops, he explains. The first one is to select the ontologies for publishing the data.  “We aim to provide every solution to either give you the right ontology or set of ontologies and terms, or to tell you that you need to extend an ontology for that particular data,” he says.

Survey Results Paint a Promising Picture for the Future of Controlled Vocabularies

The results of the survey “Do controlled vocabularies matter?” are in. We covered some preliminary findings of the survey a few weeks back, and now the complete
findings are available for download here. An article on the findings states, “Over 150 participants from 27 countries draw a picture of the current and future usage
behaviour in the realm of controlled vocabularies.”

One of the survey questions was, “Do you thing enterprises and other organizations can significantly benefit from using Linked Data?” Read more

Schema.org Can Be Useful, But RDFa Will Be Hard To Beat

 

Jay Myers, lead web development engineer at Best Buy, acknowledged that he had to make some last-minute alterations to the presentation he gave yesterday at SemTech on the practical business uses of RDFa for search engines and beyond. They were required in light of the schema.org announcement that came at the end of last week. Myers worked the new standard for creating and supporting a common vocabulary for structured data markup on web pages in microdata into a slide that showed how the Semantic Web can bring equilibrium to the pendulum that tends to swing between the shiny-ball stuff of the web that’s tailored for human consumption and the back-end keyword- and metadata-stuffing that’s done for the benefits of machine-reading.

But RDFa still takes top billing.

schema.org, Myers told the audience, is “search-centric and what I believe what the Semantic Web really entails is knowledge and insight,” he said.

DCMI and FOAF Team Up

The Dublin Core Metadata Initiative (DCMI) recently released its agreement with the Friend of a Friend Project (FOAF). According to the summary, “This agreement outlines specific measures to be undertaken in cooperation between DCMI and the FOAF Project — measures aimed primarily at reinforcing the long-term viability of the FOAF Vocabulary by addressing the risks inherent with having a single point of failure. The two organizations also see this cooperation as an opportunity for better integrating their vocabularies with alignments — mutually declared mappings between semantically overlapping terms — and for promoting the documentation of best-practice usage patterns in which the two vocabularies are used in combination.” Read more

What Inforbix is Doing for Engineers

A recent article from Inforbix comments on a quote from Lynda Moulton, writer of Semantic Software Technologies. Moulton said, “Besides baked-in intelligence for answering human questions using natural language processing (NLP) to search, an answer-platform like Watson requires tons of data. Also, data must be assembled in conceptually and contextually relevant databases for good answers to occur. When documents and other forms of electronic content are fed to a knowledgebase for semantic retrieval, finely crafted metadata (data describing the content) and excellent vocabulary control add enormous value. These two content enhancers, metadata and controlled vocabularies, can transform good search into excellent search.” Read more

SKOS and OWL 2 are Now Interoperable

In tech news, SKOS has been altered to interoperate with OWL 2. Up until now the two vocabularies haven’t been able to “play together nicely,” but thanks to a few simple tweaks to SKOS, they are now able to operate together smoothly.

According to the article, “In the semantic Web, arguably SKOS is the right vocabulary for representing simple knowledge structures, and OWL 2 is the right language for asserting axioms and ontological relationships. In the early days we chose a reliance on SKOS for the UMBEL reference concept ontology, because of UMBEL’s natural role as a knowledge structure.” Read more
