The Protocol for Web Description Resources (POWDER) is the W3C recommended method for describing web resources. It specifies a protocol for publishing metadata about Web resources using RDF, OWL, and HTTP.
The initial working party was formed in February 2007. [1] On 1 September 2009 POWDER became a W3C recommendation[2] and the Working Group is now closed.[3]
POWDER supersedes the previous W3C specification PICS.[4]
