The RDB2RDF Working Group has published two Candidate Recommendation documents that help to bring relational database information to the Semantic Web: R2RML: RDB to RDF Mapping Language and A Direct Mapping of Relational Data to RDF. The former describes R2RML, a language for expressing customized mappings from relational databases to RDF datasets. Such mappings provide the ability to view existing relational data in the RDF data model, expressed in a structure and target vocabulary of the mapping author's choice. The latter document defines a direct mapping from relational data to RDF. Implementations are invited. Test Cases are available at: http://www.w3.org/2001/sw/rdb2rdf/test-cases/. Directions on how to submit implementation reports and test case results are at: http://www.w3.org/2001/sw/rdb2rdf/wiki/Submitting_Implementation_Reports. Comments and implementation experience reports are welcome through 30 April 2012. Learn more about the Semantic Web Activity.

The Web Applications Working Group has published a Working Draft of Clipboard API and events. This specification defines the common clipboard operations of cutting, copying and pasting, in such a way that they are exposed to Web Applications and can be adapted to provide advanced functionalities. Its goal is to provide for compatibility where possible with existing implementations. Learn more about the Rich Web Client Activity.

The Web Performance Working Group has published a Last Call Working Draft of Timing control for script-based animations. This document defines an API web page authors can use to write script-based animations where the user agent is in control of limiting the update rate of the animation. The user agent is in a better position to determine the ideal animation rate based on whether the page is currently in a foreground or background tab, what the current load on the CPU is, and so on. Using this API should therefore result in more appropriate utilization of the CPU by the browser. Comments are welcome through 20 March. Learn more about the Rich Web Client Activity.
