This system is designed to support descriptive metadata for scientific data. Using descriptors and controlled vocabularies available, users should be guided through a web interface allowing quick and easy registration and maintenance of datasets that are under their custodianship. The initial aim is to produce a system that will support the UK MEDIN (a UK GEMINI Superset) metadata standard, with possible expansion to other standards at a later date.
