Protocol for Web Description Resources (POWDER): Description Resources

The purpose of the Protocol for Web Description Resources (POWDER) is to provide a means for individuals or organizations to describe a group of resources through the publication of machine-readable metadata, as motivated by the POWDER Use Cases. This document details the creation and lifecycle of Description Resources (DRs), which encapsulate such metadata. These are typically represented in a highly constrained XML dialect that is relatively human-readable. The meaning of such DRs are underpinned by formal semantics, accessible by performing a GRDDL Transform.
