Today such databases of cultural works metadata (movie descriptions, music album track lists) are illegal because you can use some of metadata (checksum of files) as identifier to associate it with actual content in p2p network. What if we modify bittorrent dht or similar thing so it'll use some other identifier: wikidata id, oclc, instead of "checksum of checksums of files"? Next day Wikipedia and library catalogs become illegal?
