Filmstandards.org root namespace
From filmstandards.org
filmstandards.org is designated as the root namespace for several metadata specifications, both public and specific to individual organizations. Even though not essential for URI schemes as such, associating an URI with a real, machine-accessible resource enables computer programs to follow directions given by the resource, e.g. validation rules, or references to further resources.
