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 requires only Microsoft Net Framework 3.5 to run, although Microsoft Access is required to edit the database.

Download and Use

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