The UK Research Data Discovery Service (UKRDS) is developing a metadata schema aimed at meeting user requirements by aligning with existing practices in the research data domain. The schema will ensure data is findable, accessible, interoperable, and reusable, with mandatory fields like creator, title, and unique resource identifier. Ongoing development will incorporate user feedback and additional requirements for richer metadata mapping.

2. UKRDDS metadata schema - aims
To produce a draft of a metadata schema to fulfil the following
criteria:
› Meet user requirements (based on the evidence provided by user cases
and correlation with common fields in use across the research data
domain).
› Simple enough (in core form) to map onto the CKAN instance that
underpins the portal.
› Based on existing schemas (and good practice) in use across the
research data domain.
› Flexible enough to develop along with the service and user needs.
