Continuing its never-ending quest to prove that it's turtles all the way up, the W3C Semantic Web Activity has updated its note on POWDER: Use Cases and Requirements:
The development of the Protocol for Web Description Resources has been motivated by both commercial and social concerns. On the social side, there is a demand for a system to identify content that meets certain criteria as they apply to specified audiences. Commercially, there is a demand to be able to personalize content for a particular user or delivery context.
POWDER will address these demands by defining a method through which relatively small amounts of metadata, that can be produced quickly and easily, can be applied to large amounts of content.
