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.

Work progress on UK GEMINI 2.3

The AGI Standards Committee intended to publish version 2.3 of UK GEMINI in early 2016. Due to delays in Europe and the UK, we are just now at the end of March 2018 launching a public review "release candidate" of GEMINI 2.3. This revision incorporates material prepared by the UK Location Programme, and currently published at data.gov.uk, and updates it for change requests from INSPIRE and other users.  AGI is grateful to Defra for funding part of this work, and for several AGI members also contributing. The new content is published under a Creative Commons license.

Please review this release candidate GEMINI 2.3, and send comments by end of April 2018 to This email address is being protected from spambots. You need JavaScript enabled to view it., copied to Peter Parslow at Ordnance Survey (chair of AGI Standards Committee). 

The INSPIRE Metadata Technical Guidelines include an informative annex describing those metadata elements which are described further in specific INSPIRE Data Specifications. In October 2017, we attempted to ask all those who have published GEMINI metadata records to data.gov.uk whether we should include these elements in GEMINI. You can find a summary of the 36 responses, and the working group's plans for each element here. We have included much of this as a new element "Data quality".

GEMINI 2.3 does not include any changes related to the publication of ISO 19115-1:2014; GEMINI will remain based on ISO 19115:2003.

Current version: 2.2, published December 2012

Version 2.2 of UK GEMINI2 includes changes requested by the UK Location Programme Metadata Working Group resulting from the implementation of the national geospatial metadata service.
