The Protocol for Web Description Resources (POWDER) allows metadata to be associated with groups of resources such as those found on a Web site. Its main 'unit of information' is the Description Resource (DR), one or more of which are contained in a POWDER document. Processing such a document yields RDF triples describing the resources that are within the scope of the DRs. POWDER documents are written in XML and have relatively loose semantics, however, a GRDDL transform, associated with the root namespace, renders the data in RDF/OWL with more formal semantics.

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier structure is used to demonstrate the providers available for Protocol for Web Description Resources (POWDER): POWDER-S Vocabulary. Some providers may use a different example, which is displayed in the table below. A guide for curating additional providers can be found here.
