Metadata is commonly defined as 'data about data'. More specifically, it is ancillary information about stored data, which aids a user in handling it, describing it and understanding what it contains. This document identifies use cases which can be considered fundamental to a Grid-like computing system for a HEP experiment and which imply requirements on the metadata catalogues used. High-energy physics use case and requirements documents have been surveyed and core use cases harvested.
