Channel Definition Format (CDF)
The Channel Definition Format (CDF) provides a mechanism to group Web resources together for various purposes. A Channel is defined as a set of documents or a grouping of content that can be "pushed", pulled, or operated on as a unit. In today's applications, the types of operations on a channel primarily involve automatic scheduled download for offline use ("smart pull"), or multicast delivery for later use. However, CDF may also provide the underlying mechanism to facilitate searching, indexing, profiling, filtering, and personalizing content independent of the publishing mechanism.
