Required, recommended, and optional metadata
Each content type we support has a unique set of requirements and recommended metadata. Contributor metadata is consistent across content types and, while not always required, has consistent recommendations if present.
Required metadata must be included or your submission will be rejected. Recommended metadata should be included to create a complete metadata record. Optional metadata should be included if relevant, but will not be relevant for most records.
