Map Repository Metadata

[BinToss]

A map registry would benefit the community if map creators utilize it.
Ideally, it should build upon the existing HAC2 map repository.

A registered map's metadata should provide the following:

DownloadURL
License (Optional)
MapEngineVersion
MapFormat (i.e. map, yelo, chimera)
MapSHA512 (built-in CRC hash is unreliable)
README (Optional)
**Thumbnail** (Optional) (as seen in main menu)
**Title** (try to inherit from built-in map name if no conflict)

Whenever possible, the destination filename is determined by the DownloadURL when downloading a map.
