GIS tools

If you produce GIS data layers using ESRI software, you can create MEDIN discovery metadata with the following tools. These tools are based around, and compatible with specific versions of ArcGIS.


ArcGIS 10.0 (service pack 3 and above), 10.1 and 10.2 stylesheet (updated 8jul14)


ArgGIS 10.0 (service pack 2 and lower) stylesheet (updated 8jul14)


ArcGIS 9 stylesheet (updated 26aug10).
Please note that the ArcGIS 9 stylesheet is currently unsupported and produces metadata designed to meet an earlier version of the MEDIN discovery metadata standard.

MEDIN has developed software to translate metadata databases into MEDIN formatted XML for inclusion on the MEDIN portal. This tool can only be applied to an existing relational database (such as in Oracle). Contact for further details.
