Content Negotiation (conneg) Working Group

Welcome to the Web site for the Content Negotiation (conneg) Working Group. The ietf-medfree mailing list is to discuss negotiating elements of the presentation of documents that are not naturally captured by the MIME Media Type.

The Working Group has concluded. The mailing list is still available, but is rarely used.

Freeware Source Code

5th Generation Messaging has provided a set of Java source code for a parser of feature set expressions in the form described in RFC2533, and an implementation of feature set matching that is a revised form of the algorithm described in RFC2533. (The revised algorithm description will be published in the forthcoming Internet Draft draft-klyne-conneg-feature-match.) The code is in the form of a set of program callable parser and feature set matching classes, together with a test harness that runs as a free-standing Java program. File "FSMNotes.txt" contains some general information about the program; more detailed information is in the form of embedded "javadoc" comments that may be extracted to HTML by the standard javadoc utility.
