Submission request to W3C

We, W3C Members Microsoft hereby submit to the Consortium the following specification comprising the document(s) linked below:

  1. Channel Definition Format [CDF]

which collectively are referred to as "the submission". We request the submission be known as the Channel Definition Format [CDF] submission.


The Channel Definition Format is an open specification that permits a web publisher to offer frequently updated collections of information, or channels, from any web server for automatic delivery to compatible receiver programs on PCs or other information appliances. Automatic means that the user need only choose the channel once, and thereafter, scheduled deliveries of information to the client will occur without further user intervention. Standard web server means that any web server that uses the HTTP 1.0 or later protocol can broadcast channels. Compatible means any program that implements processing and retrieving content as specified by the Channel Definition Format described below. When downloaded to a client, CDFs act as a local index to its channel's available content. For example, a receiver program can present the implicit hierarchy in a CDF within a channel selector.
