The ability to link to a segment within a digital audio or video file will be an important element in the future of digital scholarship. A project at the BBC explores a variation on this functionality through the use of a wikipedia-like interface that allows anyone to annotate a specific segment of audio. The BBC project is:

a demonstration of a functional working interface for the annotation of audio that’s designed to allow the collective creation of useful metadata and wikipedia-like content around radio programmes or speeches or podcasts or pieces of music.

A description, along with screencasts, is available at On the BBC Annotatable Audio project

A comment on that blog also refers to a similar project called Annodex, which looks interesting.
