The Mineral and Ore Survey System (MOSS) is a catalog of systems that have been surveyed and their associated surveys. This information is made public, along with who currently has a claim on the system. This information is considered invaluable to mining outfits and even independent operators looking to make it big.
The MOSS is administered by CORIS, the "Cooperative Ore Resource Information Services". They are an independant organization funded by all five major governments and whose board is made up of volunteers from every mining coporations who pays for membership.
A MOSS designation for a system isn't it's cononical name, but often these smaller systems don't get names so the MOSS designation has become a sort of defacto name for systems that have nothing else to identify them.
A MOSS designation is simply MOSS-<10 digit alphanumerical identifier>, i.e. MOSS-9ZG907MGTS. The CORIS gives the designation and that designation isn't supposed to ever change. (Practically, it can happen, but it's mostly clerical error.)
This system is slightly modeled off the "Common Land Units" used in crop insurance.
The alphanumerical identifiers I'm using are generated by NanoID. Simply set the alphabet to 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ, and the length to 10. To generate a new one from that page, simply slide the slider for the length up or down one, then back to 10.
