A metadata standard or schema is a set group of elements that have been standardized for a particular field of research. A DMP should describe what metadata schema will be used and why that particular schema is appropriate for the research data that will be preserved.

This section will provide information on various metadata schemas and links to more information about them.
These are some suggested minimal metadata elements to use when you are documenting your data:
