Eleven SPARQL 1.1 Specifications Published

08 November 2012 | Archive

The SPARQL Working Group has today published a set of eleven documents, advancing most of SPARQL 1.1 to Proposed Recommendation. Building on the success of SPARQL 1.0, SPARQL 1.1 is a full-featured standard system for working with RDF data, including a query/update language, two HTTP protocols (one full-featured, one using basic HTTP verbs), three result formats, and other features which allow SPARQL endpoints to be combined and work together. Most features of SPARQL 1.1 have already been implemented by a range of SPARQL suppliers, as shown in our table of implementations and test results.

The Proposed Recommendations are:

1. SPARQL 1.1 Overview - Overview of SPARQL 1.1 and the SPARQL 1.1 documents
2. SPARQL 1.1 Query Language - A query language for RDF data.
3. SPARQL 1.1 Update - Specifies additions to the query language to allow clients to update stored data
4. SPARQL 1.1 Query Results JSON Format - How to use JSON for SPARQL query results
5. SPARQL 1.1 Query Results CSV and TSV Formats - How to use comma-separated values (CVS) and tab-separated values (TSV) for SPARQL query results
6. SPARQL Query Results XML Format - How to use XML for SPARQL query results. (This contains only minor, editorial updates from SPARQL 1.0, and is actually a Proposed Edited Recommendation.)
7. SPARQL 1.1 Federated Query - an extension of the SPARQL 1.1 Query Language for executing queries distributed over different SPARQL endpoints.
8. SPARQL 1.1 Service Description - a method for discovering and a vocabulary for describing SPARQL services.

The following are Candidate Recommendations, as the group still seeks more feedback from implementors:

1. SPARQL 1.1 Entailment Regimes - defines the semantics of SPARQL queries under entailment regimes such as RDF Schema, OWL, or RIF.
2. SPARQL 1.1 Protocol for RDF - A protocol defining means for conveying arbitrary SPARQL queries and update requests to a SPARQL service.
3. SPARQL 1.1 Graph Store HTTP Protocol - As opposed to the full SPARQL protocol, this specification defines minimal means for managing RDF graph content directly via common HTTP operations.

The group has also produced a test suite and a page on using SPARQL 1.1 with RDF 1.1. Learn more about the Semantic Web.

CSS Text Module Level 3, CSS Text Decoration Module Level 3 Drafts Published

13 November 2012 | Archive

The Cascading Style Sheets (CSS) Working Group has published two Working Drafts today.

• CSS Text Module Level 3. This CSS3 module defines properties for text manipulation and specifies their processing model. It covers line breaking, justification and alignment, white space handling, and text transformation.
• CSS Text Decoration Module Level 3. This module contains the features of CSS relating to text decoration, such as underlines, text shadows, and emphasis marks. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc.

XML Encryption 1.1 and XML Signature 1.1 Interop Test Reports Published

13 November 2012 | Archive

The XML Security Working Group has published two Group Notes today.

• XML Encryption 1.1 Interop Test Report. This document is the interop report for new features introduced in XML Encryption 1.1. It does not replicate interop testing performed for features retained from XML Encryption 1.0.
• XML Signature 1.1 Interop Test Report. This document is the interop report for new features introduced in XML Signature 1.1. It includes the test cases and test results for these new features. It does not replicate interop testing performed for features retained from XML Signature 1.0.

W3C Launches Pointer Events Working Group

09 November 2012 | Archive

W3C announced today the launch of the Pointer Events Working Group. Web browsers can receive input in a variety of ways. A “pointer” is an abstract form of input that can be any point of contact on a input surface made by a mouse cursor, pen, finger, or multiple fingers. The mission of this group is to define a single unified event model for mouse, touch, and pen/tablet user interfaces. Enabling content creators to use a single model for different input types will make content creation more efficient and inclusive. See the Pointer Events Working Group Charter for more information.
