OMSS Documentation

This page lists all reserved namespaces in OMSS Core, along with the order of values that are allowed in each namespace. Reserved namespaces are used to ensure that certain identifier values are unique and consistent across all OMSS Core implementations. The following namespaces are currently reserved:

TMDB

Website: https://www.themoviedb.org/

Movie: tmdb:<movie_id> - e.g., tmdb:329865 for https://www.themoviedb.org/movie/329865-arrival
TV Episode: tmdb:<show_id>:<season>:<episode> - e.g., tmdb:87108:1:4 for https://www.themoviedb.org/tv/87108-chernobyl/season/1/episode/4

All values must be natural numbers (≥ 1), except season_number which may be 0 (specials).
