Three RDFa Recommendations Published

The RDFa Working Group today published three RDFa Recommendations. RDFa lets authors put machine-readable data in HTML documents. Using RDFa, authors may turn their existing human-visible text and links into machine-readable data without repeating content. Today’s publications were:

  • HTML+RDFa 1.1, which defines rules and guidelines for adapting the RDFa Core 1.1 and RDFa Lite 1.1 specifications for use in HTML5 and XHTML5. The rules defined in this specification not only apply to HTML5 documents in non-XML and XML mode, but also to HTML4 and XHTML documents interpreted through the HTML5 parsing rules.
  • The group also published two Second Editions for RDFa Core 1.1 and XHTML+RDFa 1.1, folding in the errata reported by the community since their publication as Recommendations in June 2012; all changes were editorial.

Three More SPARQL1.1 Documents Translated to Japanese

上綱 秀治 (Shuji Kamitsuna) published a Japanese translation of the W3C document “SPARQL 1.1 Service Description” under the title “SPARQL 1.1サービス記述”, of the “SPARQL Query Results XML Format (2nd Edition)” under the title “SPARQLクエリ結果XMLフォーマット(第2版)”, and of the “SPARQL 1.1 Federated Query” under the title “SPARQL 1.1統合クエリ”.

Three Group Notes and a Last Call Draft published by the W3C Government Linked Data WG

The Government Linked Data Working Group has published three Group Notes and a Last Call Working Draft today:

  • Group Note of Use Cases and Lessons for the Data Cube Vocabulary. Many national, regional and local governments, as well as other organizations in- and outside of the public sector, collect numeric data and aggregate this data into statistics. There is a need to publish these statistics in a standardized, machine-readable way on the Web, so that they can be freely integrated and reused in consuming applications.
  • Group Note of Registered Organization Vocabulary. The Registered Organization Vocabulary is a profile of the Organization Ontology for describing organizations that have gained legal entity status through a formal registration process, typically in a national or regional register.
  • Group Note of Asset Description Metadata Schema (ADMS). ADMS is a profile of DCAT, used to describe semantic assets (or just ‘Assets’), defined as highly reusable metadata (e.g. xml schemata, generic data models) and reference data (e.g. code lists, taxonomies, dictionaries, vocabularies) that are used for eGovernment system development.
  • Last Call Working Draft of Data Catalog Vocabulary (DCAT). DCAT is 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. Comments are welcome through 30 August.

Special session on the long term preservation of RDF vocabularies at DC-2013

W3C has the pleasure to sponsor the Special Session on the Long-term Preservation and Governance of RDF Vocabularies, part of the DC-2013 conference in Lisbon, Portugal, on Tuesday, September 3, 2013. See also the Discussion paper for the special session, authored by Tom Baker, Bernard Vatant, and Pierre-Yves Vandenbussche.

Linked Data Platform in Last Call Working Draft

The Linked Data Platform (LDP) Working Group has published a Last Call Working Draft of Linked Data Platform 1.0. This document describes a set of best practices and simple approach for a read-write Linked Data architecture, based on HTTP access to web resources that describe their state using the RDF data model. Comments are welcome through 02 September.

Two Drafts in Last Call: RDF 1.1 Concepts and Abstract Syntax, RDF 1.1 Semantics

The W3C RDF Working Group has published two Last Call Working Drafts:

  1. A Last Call Working Draft of RDF 1.1 Concepts and Abstract Syntax. The Resource Description Framework (RDF) is a framework for representing information in the Web. Comments are welcome through 6 September.
  2. A Last Call Working Draft of RDF 1.1 Semantics. This document describes a precise semantics for the Resource Description Framework 1.1 and RDF Schema. It defines a number of distinct entailment regimes and corresponding patterns of entailment. It is part of a suite of documents which comprise the full specification of RDF 1.1. Comments are welcome through 6 September.

Linked Data Glossary

The W3C Government Linked Data Working Group has published a Group Note of Linked Data Glossary. This document is a glossary of terms defined and used to describe Linked Data, and its associated vocabularies and Best Practices. This document will help information management professionals, Web developers, scientists and the general public better understand publishing structured data using Linked Data Principles.

Call for Implementations: Org and Data-Cube Vocabularies

The W3C Government Linked Data (GLD) Working Group today published two Candidate Recommendations:

  • The Organization Ontology (org) defines a vocabulary for describing the structure of an organization, such as a government agency or a corporation.
  • The RDF Data Cube Vocabulary (data-cube) allows multi-dimensional data, such as statistics or environmental data, to be published on the Web in a standard way.

Each of these vocabularies is stable and has already been used in a variety of applications (see org implementations and data cube implementations). The group is now encouraging everyone who wants to provide or consume this kind of data to begin using these vocabularies, and it asks people to please send in reports of implementation experience, as explained in the documents. These reports will help us be sure the vocabularies are ready to become W3C Recommendations and generally help build global interoperability.
