The W3C POWDER Working Group has published a new working draft of Protocol for Web Description Resources (POWDER): Description Resources.
The Protocol for Web Description Resources (POWDER) facilitates the publication of descriptions of multiple resources such as all those available from a Web site. These descriptions are always attributed to a named individual, organization or entity that may or may not be the creator of the described resources. This contrasts with more usual metadata that typically applies to a single resource, such as a specific document's title, which is usually provided by its author.
This document sets out how Description Resources (DRs) can be created and published, how to link to DRs from other online resources, and, crucially, how DRs may be authenticated and trusted. The aim is to provide a platform through which opinions, claims and assertions about online resources can be expressed by people and exchanged by machines. POWDER has evolved from the data model developed for the final report [XGR] of the Web Content Label Incubator Group [WCL-XG] from which we define a Description Resource as: "a resource that contains a description, a definition of the scope of the description and assertions about both the circumstances of its own creation and the entity that created it."
