Linkset: Media Types and a Link Relation Type for Link Sets
draft-wilde-linkset-06
Abstract
This specification defines two document formats and respective media
types for representing sets of links as stand-alone resources. One
format is JSON-based, the other aligned with the format for
representing links in the HTTP "Link" header field. This
specification also introduces a link relation type to support
discovery of sets of links.
