Members of the WAM team participate, or have participated, in the development of W3C standards.


W3C created the first Synchronized Multimedia Working Group in 1995, with the goal of adapting multimedia documents to the Web, defining temporal relations between different information pieces in a document, and planning how text, sound, images and video fit together in the display space as well as in time. This work group has developed a language called SMIL, to which WAM researchers greatly contributed through concepts developed during early research work, in particular in Nabil Laya´da's doctoral thesis.

The following versions of the standard have been co-edited or co-authored by researchers from the WAM team:

The latest standardized version of the language is SMIL 3.0 (December 2008). The work group has also designed SMIL Timesheets 1.0, an XML timing language that makes SMIL elements and attributes available to a wide range of other XML languages, for which WAM has developed an implementation.


W3C has launched the Points of Interest (POI) Working Group in September 2010 to develop technical specifications for the representation of Points of Interest information on the Web. Jacques Lemordant participates in this group and makes experiments based on the group discussions, especially in the Mixed Reality Browser.


To make early experiments with web standards during their design phase and to help deployment, WAM has implementated W3C standards in various software projects:

An on-line web editor implementing HTML, XHTML, CSS, SVG. Its annotation tool also uses XLink, XPointer, and RDF.
A multimedia authoring tool supporting SMIL as an output format.
Timesheets Library
A Javascript library implementing SMIL Timesheets 1.0 that can run in any browser.
Mixed Reality Browser
A POI browser running on the iPhone, that can display HTML5 multimedia data associated with POIs.
