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 started on UK GEMINI 2.3

The AGI Standards Committee had intended to publish version 2.3 of UK GEMINI in early 2016. Due to delays in Europe and the UK, this will now be the first half of 2017. This revision will incorporate material prepared by the UK Location Programme, and currently published at, and update it for change requests from INSPIRE and other users.  AGI is grateful to Defra for funding this work.

For a taste of the new consolidated structure, currently with GEMINI 2.2 content, see restructured GEMINI. The new content will be published under a Creative Commons license.

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

Previously, this page mentioned GEMINI 3, but the technical changes to GEMINI are quite minor, and should be backward compatible, so we have decided to call this next release GEMINI 2.3. The INSPIRE profile will contain some new mandatory items, so at some point - under their control - GEMINI 2.2 records will not be acceptable to INSPIRE.

Summary of change requests raised to AGI, other than from INSPIRE

  • clear guidance on use of Digital Object Identifiers
  • fuller guidance on providing citation details
  • clarify the use of ISO 19115’s ‘distribution’ and ‘distributor’ elements
  • guidance on using HTTP URIs as key words
  • consider the suitability of adopting UK Locations recommendation to use the Eden schemas

A number of change requests were considered by the GEMINI Working Group. The changes are described in this document which you can download:
