[feature article] Metadata is one of those words that gets bandied about a lot at conferences and by various groups, particularly within broadcasting and digital library circles. But it is also cropping up in numerous other fields, such as digital rights management, content delivery, business models for the music industry, and so forth. The field is rife with acronyms and arcane terms that leave the uninitiated baffled, particularly because metadata is really more concerned with information systems than it is with audio. This article aims to demystify metadata for audio professionals and to explain some of the key terms and developments. It is based partly on the AES Metadata Symposium that was run in conjunction with the 112th Convention in Munich last year, but it goes back to basics in order to make the topic approachable for the relative novice.
