MEDIN discovery metadata standard icon

Discovery metadata is a list of information that accompanies a data set and allows other people to find out what the data set contains, where it was collected and how they can get hold of it.

MEDIN have produced a standard for marine metadata and a set of tools to create metadata records that comply with the MEDIN Metadata Standard.

Metadata Standard Guidance notes

The MEDIN Discovery Metadata Standard is a marine profile of the UK government Standard GEMINI2 and also complies with other international conventions such as INSPIRE and ISO19115.

Currently, MEDIN has two versions of its Metadata Standard available to users.

These are: (a) v2.3.8, which has been in use for a number of years and (b) v3.1.2, recently updated by MEDIN to comply with the updated GEMINI v2.3 UK geospatial standard.

MEDIN are engaged in an ongoing process of updating its metadata creation tools and discovery metadata portal to work with v3.1.2. Please note that MEDIN’s intention is, once the tools and portal are updated, to retire v2.3.8 of the Standard.
