Submission request to W3C (W3C Team Comment)

Timesheets: XML Timing Language

We, W3C Member Helsinki Univerisity of Technology hereby submit to the Consortium the following specification, comprising the following document(s) attached hereto:

  1. Timesheets: XML Timing Language

which collectively are referred to as "the Submission". We request the Submission be known as the Timesheets Submission.


This document specifies a new language for introducing temporal control to XML documents. The XML Timing language (Timesheets) is included as a distinctive section in a document and it assigns the timing information to the elements in the other sections of the document, in the same way the Cascading Style Sheets assign spatial properties to the elements.

Compared to SMIL, the XML Timing language can be seen as a different approach to the timing of XML documents. It reuses a subset of timing primitives from the Timing and Synchronization module of SMIL 2.0, but separates content, styling and timing for easier authoring and maintenance of multimedia documents.
