Logging/Source data

There should be schema to contain classic logging/source data.

Candidate items could include:

- reel/tape name
- Production Name
- scene
- take
- slate
- shoot day
- shoot date
- Circle take (true/false)

### Open Questions

- Would this attach at a Media Reference or clip level?

Start by reviewing the linked FCP 7 XML filmdata and timecode/reel elements, the Avid Log Specification from page 97, and the OpenEXR Editorial attributes. Resolve whether the metadata belongs on a Media Reference or clip, then define a schema covering the listed logging fields; done means the attachment level and schema are agreed.
