The Problem
There are infinite ways to publish media by users, but as people try to access those remixing and aggregation become more and more prevalent, having consistent records becomes important. Audio, photos and video show up in each other's publishing spaces, even though they are unique media objects. A photo might be next to the link for an audio piece, as it's visual artwork. A video can be comprised of quotes of other videos, photos and audio. Still photos can be made from videos. All three types of objects can contain subsets of media that is tagged and described. Having a single publishing format to relate them as needed in an organized structure makes sense.
Elements that come up often in practice
Here are some examples of elements that might be included because they seem to come up often in user generated media publishing, either on their own blogs or on service sites, include the following:
Base elements:
- Title
- Html URL
- Media URL
- Image URL (video)
- Tags
- Description / summary
- Quotes (subsets of the object: a video quote and tags/description associated with it, a region annotation note for a photo, or the quote of a podcast or audio piece, with tags/description -- the technical detail for these subsets exists in the 'more info' section below)
- Creator
- License (defaults to copyright, if none exists, but it's there, by US law, and many other areas of the world)
and for audio and visual:
- Duration
Other info: (This is not the same for all types of media, and is published by users in very limited ways in practice, or is captured from the device or service or in some way, invisible to the user, and therefore often depends on a service to pick it up. It should only appear in a publishing tool under 'more data' at then end, for enthusiast users.)
