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 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 summer 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.

Work to be contracted

AGI requests proposals, with charging rates and time estimates, to update the UK GEMINI content on the AGI development website to take account of revised INSPIRE Metadata Technical Guidance; update the associated Schematron files; and further restructure that content to be more internally consistent and user-friendly. AGI use Joomla as their content management system.

Submission of bids

The work is being offered in two work packages Work Package 3 and Work Package 4. Bidders may bid for either of these Work Packages or both but a separate submission must be made for each Work Package. Work on Work Package 4 cannot commence until that on Work Package 3 has been completed and accepted by the AGI Standards Committee.

  • Acceptance of the terms and conditions
  • charging rate, with VAT indicated as a separate item
