W3C Invites Implementations of High Resolution Time and Resource Timing

22 May 2012 | Archive

The Web Performance Working Group invites implementation of two Candidate Recommendations:

  • High Resolution Time.This specification defines a JavaScript interface that provides the current time in sub-millisecond resolution and such that it is not subject to system clock skew or adjustments.
  • Resource Timing. This specification defines an interface for web applications to access the complete timing information for resources in a document.

MediaStream Processing API Note Published

31 May 2012 | Archive

The Audio Working Group has published a Group Note of MediaStream Processing API. A number of existing or proposed features for the Web platform deal with continuous real-time media. Many use-cases require these features to work together. This proposal makes HTML Streams the foundation for integrated Web media processing by creating a mixing and effects processing API for HTML Streams. Learn more about the Rich Web Client Activity.

Two Last Call Working Drafts published by the RDB2RDF Working Group

29 May 2012 | Archive

The RDB2RDF Working Group has published two Last Call Working Drafts today:

  • A Direct Mapping of Relational Data to RDF. The need to share data with collaborators motivates custodians and users of relational databases (RDB) to expose relational data on the Web of Data. This document defines a direct mapping from relational data to RDF. This definition provides extension points for refinements within and outside of this document. Comments are welcome through 19 June.
  • R2RML: RDB to RDF Mapping Language. This document 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. R2RML mappings are themselves RDF graphs and written down in Turtle syntax. R2RML enables different types of mapping implementations. Processors could, for example, offer a virtual SPARQL endpoint over the mapped relational data, or generate RDF dumps, or offer a Linked Data interface. Comments are welcome through 19 June.

Three documents published by the Web Applications Working Group

29 May 2012 | Archive

The Web Applications Working Group has published three documents today:

  • First Public Working Draft of Gamepad. The Gamepad specification defines a low-level interface that represents gamepad devices.
  • First Public Working Draft of Pointer Lock. This specification defines an API that provides scripted access to raw mouse movement data while locking the target of mouse events to a single element and removing the cursor from view. This is an essential input mode for certain classes of applications, especially first person perspective 3D applications and 3D modelling software.
  • Group Note of The From-Origin Header. The From-Origin Header specification defines the From-Origin response header -- a way for resources to declare they are unavailable within an embedding context.
