Cascading Style Sheets Standard Boasts Unprecedented Interoperability

W3C announced new levels of support today for Cascading Style Sheets (CSS), the language for adding style to Web content. W3C released an update to the core CSS standard, CSS 2.1, to reflect the current state of support for CSS features, and to serve as the stable foundation for future extensions.
CSS has been in widespread use as an Open Web technology for more than a decade, but it took many years for implementations and the specification to converge. The collective efforts of the CSS Working Group, implementers, contributors to the CSS Test Suite, and the W3C CSS community have made interoperable CSS a reality for the Open Web. More than 9000 CSS tests have made it easier for designers to create style sheets that work across browsers, and across devices. "This publication crowns a long effort to achieve very broad interoperability," said Bert Bos, co-inventor of CSS and co-Editor of CSS 2.1." Now we can turn our attention to the cool features we've been itching to bring to the Web."
The CSS Working Group also published two other Recommendations today:
CSS Color Module Level 3 and A MathML for CSS Profile. Read the

Incubator Group Report: Semantic Sensor Network XG Final Report

The W3C Semantic Sensor Network Incubator Group has published their final report. As networks of sensors become more commonplace there is a greater need for their management and querying to be assisted by standards and computer reasoning. Building on the OGC's Sensor Web Enablement services-based architecture and standards, including four description languages, the group produced ontologies for describing sensors and extended a language to support semantic annotations. The report lists use-cases and reviews existing ontologies leading to the selection of the SSN ontology, analyzes examples and semantic markup as well as mapping to existing standards. The report also includes a list of directions for future work in the context of Linked Sensor Data, or Semantic Internet of Things for work at the border of Internet of Things and Internet of Service. The group plans to create a W3C Community Group to focus on the maintenance and extension of the SSN Ontology.
This publication is part of the Incubator Activity, a forum where W3C Members can innovate and experiment. This work is not on the W3C standards track.
