Interesting Times


CDF is mixing markup languages into a single document.

Our approach is to build a framework for the general case and a set of profiles for specific combinations.

Primary use case is the mobile market.

CDF Use Cases

The CDF Working Group has published a document of use cases and requirements.

Status of CDF

CDF is about to release the first draft of an XHTML + SVG multimedia presentation profile.

There is strong participation in the CDF group including Nokia, Sony Ericsson, Mozilla, Access, RIM, Vodafone, France Telecom, Opera, Obigo, Ikivo.


XBL is a mapping from custom markup into presentation and behaviour. The goal is to keep the semantically rich content as close to the user as possible.

XBL Example

  <s:star magnitude="10"/>

  s = doc.createElementNS(SNS, "star");
  s.setAttribute("magnitude", "20");
  s.addEventListener("Supernova", callback, false);
