This is an exploratory page to be used for storage of various multimedia metadata profiles currently in use around the web. As this is a very, very early exploration, we should include as many types of multimedia as possible in the opening discussion - but please be sure to place your profiles in the correct portion of this page.

Purpose of this exploration (or : The Problem)

The purpose of the studies on this page is to determine the feasibility and demand for a flexible, semantic markup format for providing metadata alongside linked multimedia files. Typically, this metadata is stored within the header of the media file itself - which has massive implications for any application where metadata is to be indexed, searched, or made externally accessible. Of course, even if you could easily access the correct portions of a media file remotely, you'd still have to cope with a multitude of open and proprietary metadata formats, each with it's own distinct fieldset, nomenclature and storage method.

This study aims to make a start at solving this problem.
