UK GEMINI (GEo-spatial Metadata INteroperability iNItiative) is a specification for a set of metadata elements for describing geospatial data resources. It has been produced and is maintained by the Standards Committee. It is provided free of charge by the AGI for the benefit of the GI community, under a Creative Commons license.
If you're thinking, "why GEMINI? Why not just use the INSPIRE Metadata guidance or the ISO standards?" Click here for some reasons.
The AGI Standards Committee has now published version 2.3 of UK GEMINI, in June 2018.
This revision incorporates material prepared by the UK Location Programme, previously published at data.gov.uk, and material previously published as separate guidance documents. We hope this consolidation will make it easier for you to use. GEMINI has also been updated for change requests from revised INSPIRE guidance, and UK users. AGI is grateful to Defra for funding part of this work, and for several AGI members also contributing.
The existing guidelines on the quality of metadata still apply: Guidelines for UK GEMINI Part 3 Metadata Quality
UK INSPIRE have announced their intention to require data publishers to migrate to GEMINI 2.3 by December 2019, in line with the target date from Europe for adopting the current version of their INSPIRE Technical Guidance. UK INSPIRE, and the data.gov.uk system in particular, will continue to accept GEMINI 2.2 records encoded according to UK Location guidance, at least until then - although they may generate warning messages from the EU portal.
GEMINI 2.3 does not include any changes related to the publication of ISO 19115-1:2014; GEMINI remains based on ISO 19115:2003.
