title: Channel Definition Format
|
||||
---
|
||||
|
||||
The Channel Definition Format was a Microsoft file format for syndication
|
||||
based on XML. It was designed for its *Active Channels* technology and got
|
||||
extended for *Active Desktop* integration or for [OSD][osd].
|
||||
|
||||
## Specification (or lack thereof)
|
||||
|
||||
CDF does not have a standardized specification: [a note][w3c] was sent to the
|
||||
W3C in 1997 with a very early draft of the format, with the intention of later
|
||||
making it into a standard, but there were no further updates.
|
||||
The [Microsoft docs][docs-970314] of that time are the same as this draft.
|
||||
|
||||
The [latest documentation][docs], from 2002, describes a format that varies a
|
||||
lot from that W3C note.
|
||||
|
||||
There is no official <abbr title="Document Type Definition">DTD</abbr> or
|
||||
<abbr title="XML Schema Definition">XSD</abbr>. Someone wrote a [DTD][dtd]
|
||||
with support for the *Active Desktop* and [OSD][osd] extensions.
|
||||
|
||||
I wrote my own XSD files to help me use this format in [ITSB][itsb]:
|
||||
|
||||
* [W3C draft](./xsd/cdf-w3c.xsd)
|
||||
* [CDF 0.4](./xsd/cdf.xsd) (latest)
|
||||
|
||||
## Support
|
||||
|
||||
CDF was supported by Internet Explorer 4 to 7, and no other software is known
|
||||
to have supported this format.
|
||||
|
||||
The format was created and implemented in IE4 while XML was still a draft,
|
||||
causing some valid XML documents to not be understood properly by IE4, and all
|
||||
the sample CDF files provided with IE4 to make XML parsers scream.
|
||||
|
||||
Support was dropped in 2009 with the release of IE8 as it lost against RSS,
|
||||
and as Microsoft's dedicated RSS team implemented RSS support in IE7.
|
||||
|
||||
## Notable features
|
||||
|
||||
* Scheduling options to avoid useless synchronizations
|
||||
* Nested channels (merge multiple feeds into one)
|
||||
* Custom icons in the IE favorites sidebar
|
||||
* Customization of IE's crawling behavior when making a website available
|
||||
offline, using `<LINK REL="OFFLINE" HREF="...cdf">`
|
||||
* *Active Desktop* integration to display articles on the desktop
|
||||
* Integration with [Open Software Description][osd] to send software updates
|
||||
|
||||
## Usage
|
||||
|
||||
I use this format in [ITSB][itsb] to provide separate channels generated from
|
||||
each RSS feed, or channels that group channels together. This second form
|
||||
usually causes Internet Explorer to lag heavily due to the few megabytes of
|
||||
items it is downloading in a single file. All of those CDF files have been
|
||||
tested and confirmed to be working with Internet Explorer 6 SP1 on Windows
|
||||
2000 SP4.
