Meta-Data handling is a bit confusing at present. There are several kinds of meta-data to consider:
- Dump-Level meta-data
- License
- Schema version
- Generator version
- Generation timestamp
- Description document meta-data
- relationship with entity
- Revision meta-data (applies to the description, not the entity)
- id
- timestamp
Dump-level meta-data should *always* be included in the output. Description and revision meta-data for each entity are optional.
