| Graphics homeGraphics continue to play a critical role in everyday usage of the Web, from decorative graphics through advertising to diagrams and interactive graphical user interfaces. Graphical front-ends for live networked data, Web services, and visualizations of the Semantic Web are current growth areas as is the use of graphics in industrial control, automation, and embedded applications.
The W3C Graphics Activity has worked in this area for over ten years. Scalable Vector Graphics (SVG), the current effort of the Activity, brings the powerful combination of interactive, animated two-dimensional vector graphics and Extensible Markup Language (XML). WebCGM 2.0 is used mainly in industrial and defence technical documents. Earlier work was concerned with Portable Network Graphics (PNG) and with WebCGM 1.0.
This six month period was characterised by a focus on testing, errata, and such 'life after Rec' activity.
Work on an SVG Tiny 1.2 test suite has made good progress, and a test-fest was held in June. It uses converted SVG 1.1 tests, new tests created by the Working Group, and tests contributed by implementors. 3GPP and OMA depend on the SVG Tiny 1.2 specification; W3C and OMA intend to collaborate on SVG Tiny 1.2 test suite development. In September 2007, an SVG Tiny 1.2 test suite was released, together with an interim implementation report.
For SVG 1.1, a much awaited errata document was published in April 2007 and further updates are in preparation.
WebCGM 2.0 was jointly published in January 2007 as a W3C Recommendation and an OASIS standard (press release). The WebCGM Working Group requested a charter extension through November 30 th 2007. The group is currently processing WebCGM 2.0 errata for public release soon. Errata for WebCGM 1.0 are now available for review before publication at final destination. The WebCGM Working Group is also collecting requirements for a possible future WebCGM 2.x version. The Aerospace and Defence standard S100D release 3, uses WebCGM 2.0.
The SVG Working Group continues to work closely with the Compound Document Formats (CDF) Working Group to specify interoperable, mixed-namespace documents which include XHTML, SVG, and XForms.
Work was restarted on SVG Print, which was earlier presented at the W3C Print Symposium in Heidelberg. New Working Drafts of SVG Print and its associated Primer were published in May 2007; the specification will go to Last Call soon. An SVG Full 1.2 module, Filters was released along with a Filters primer. This functionality, originally part of SVG 1.1, is refactored here as a separate SVG 1.2 module, extending SVG Tiny 1.2 but which may also be used by other specifications.
A joint effort of the SVG and Web API Working Groups, the REX Task Force has held a PAG related to Remote Events for XML (REX) 1.0. The PAG report listed some prior art, but then suggested closing work on REX 1.0.
SVG Tiny 1.2 is a Candidate Recommendation. Its test suite and implementation report indicate that are several implementations show promising levels of coverage and interoperability. Once the dependent specifications have moved to an appropriate level, it is expected that SVG Tiny 1.2 will progress to Proposed Recommendation in the next six months. Work on SVG 1.2 Full will continue, as a modularized set of extensions to the core SVG Tiny 1.2.
The position of Team Contact for the SVG Working Group was advertised; the position was filled by Doug Schepers, who joined the W3C Team in July 2007.
