With MMS Metadata you can:

• view and edit metadata on active themes through a dialog with 5 tab-pages: General Information, Creation History, Table Metadata, Quality Information, Environment Metadata
• make txt, html and xml reports of all metadata and define the contents of the reports dynamically
• make metadata categories based on the theme keyword item, a function that creates a whole new type of TOC: MMS TOC (adding structure to your themes!)
• query the metadata that is saved in the MMS metadata-database with the MMS querybuilder
• remove the saved metadata from MMS metadata database with the same MMS querybuilder
• use domainvalues to speed up the creation of metadata and to prevent mistakes
• import metadata textreports to the dialogs when two or more themes have partially the same metadata contents
• save metadata in 1 or more databases (located in the MMS homedirectory) and eventually join 2 or more databases together
• as MMS works on active themes, you can activate themes by choosing them out of a list (menu-item)
• edits on the database are written to a logfile that can be used later
• change settings, like MMS homedirectory, report contents, domain fields and values, required metadata fields, etc
• in the ArcView TOC, MMS can indicate if a theme has metadata by adding "+ Metadata!" to the themename
• lots of small extras, like thumbnails in html reports, the ODB (read/write) function, legend metadata, metadata editor info, relocating replaced datasets, etc
