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.
