MME: Minnesota Metadata Editor

MME software allows users to view and edit metadata (documentation) using the Minnesota Geographic Metadata Guidelines (MGMG). MGMG is a streamlined version of a national metadata standard.


MME runs as a portable application and needs no installation. It does not interact with Windows or ArcGIS. Installing the application to a network drive is not recommended.
