Media Feature Tag Registration Procedure

Recent Internet applications, such as the World Wide Web, tie together a great diversity in data formats, client and server platforms, and communities. This has created a need for content feature descriptions and negotiation mechanisms in order to identify and reconcile the form of information to the capabilities and preferences of the parties involved. Extensible content feature identification and negotiation mechanisms require a common vocabulary in order to positively identify content features. A registration process and authority for content features is defined with the intent of sharing this vocabulary between communicating parties. In addition, a URI tree is defined to enable sharing of content feature definitions without registration. This document defines a registration procedure which uses the Internet Assigned Numbers Authority (IANA) as a central registry for the content feature vocabulary.
