POWDER Formal Semantics First Working Draft Published
The W3C Protocol for Web Description Resources (POWDER) Working Group has published the First Public Working Draft of Protocol for Web Description Resources (POWDER): Formal Semantics. This document underpins the Protocol for Web Description Resources (POWDER). It describes how the relatively simple operational format of a POWDER document can be transformed through two stages, first into a more tightly constrained XML format (POWDER-BASE), and then into an RDF/OWL encoding (POWDER-S) that may be processed by Semantic Web tools. The formal semantics of POWDER are best understood after the reader is acquainted with the Description Resources and Grouping of Resources documents.
