NIP-35

Torrents

draft optional

This NIP defined a new kind 2003 which is a Torrent.

kind 2003 is a simple torrent index where there is enough information to search for content and construct the magnet link. No torrent files exist on nostr.

Tags

• x: V1 BitTorrent Info Hash, as seen in the magnet link magnet:?xt=urn:btih:HASH
• file: A file entry inside the torrent, including the full path ie. info/example.txt
• tracker: (Optional) A tracker to use for this torrent

In order to make torrents searchable by general category, you SHOULD include a few tags like movie, tv, HD, UHD etc.

Tag prefixes

Tag prefixes are used to label the content with references, ie. ["i", "imdb:1234"]

• tcat: A comma separated text category path, ie. ["i", "tcat:video,movie,4k"], this should also match the newznab category in a best effort approach.
• newznab: The category ID from newznab
• tmdb: The movie database id.
• ttvdb: TV database id.
• imdb: IMDB id.
• mal: MyAnimeList id.
• anilist: AniList id.

A second level prefix should be included where the database supports multiple media types.

• tmdb:movie:693134 maps to themoviedb.org/movie/693134
• ttvdb:movie:290272 maps to thetvdb.com/movies/dune-part-two
• mal:anime:9253 maps to myanimelist.net/anime/9253
• mal:manga:17517 maps to myanimelist.net/manga/17517

In some cases the url mapping isnt direct, mapping the url in general is out of scope for this NIP, the section above is only a guide so that implementers have enough information to succsesfully map the url if they wish.

Torrent Comments

A torrent comment is a kind 2004 event which is used to reply to a torrent event.

This event works exactly like a kind 1 and should follow NIP-10 for tagging.
