Network Working Group K. Holtman Request for Comments: 2506 TUE BCP: 31 A. Mutz Category: Best Current Practice Hewlett-Packard T. Hardie Equinix March 1999 Media Feature Tag Registration Procedure Status of this Memo This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (1999). All Rights Reserved. ABSTRACT 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 media 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 media feature identification and negotiation mechanisms require a common vocabulary in order to positively identify media features. A registration process and authority for media features is defined with the intent of sharing this vocabulary between communicating parties. In addition, a URI tree is defined to enable sharing of media feature definitions without registration. This document defines a registration procedure which uses the Internet Assigned Numbers Authority (IANA) as a central registry for the media feature vocabulary.
