Concepts¶

Ideas of the dictionary that are neither a table nor a field.

Concept	Definition	Purpose
Song group	Every video with the same album artist, title and track artist. The performer counts, so a film song covered by two artists is two groups.	The unit the work is done in (one group at a time) and the unit that has one Primary.
Primary pending	A note in a video's comment: the group has no official video, so the Primary is decided after the downloads by resolution, then views.	Keeps the Primary open until the file quality is known.
Wikipedia wins	When Lidarr and Wikipedia disagree on album, year, disc or track, Wikipedia's answer is used and the difference is logged.	Settles which source is trusted.
Original studio album	The release group of type Album with the earliest first release; a song with none is filed as a single or under its soundtrack.	Decides which album a song is filed under, whatever version the video shows.
Data point	One fact about an artist or song found by a search, held as a candidate until it is verified.	The unit that is verified, scored and, when verified, promoted into its column.
Verified	A data point that has passed verification: its page was examined and it is tied to the artist by an anchor or by a link from a verified page.	Only verified data points add to the identity score.
Anchor	An artist identity established by hard evidence: a MusicBrainz match by recording credit, our own video's channel, or the owner's word.	The starting point of the chain of trust.
Chain of trust	Trust flows from an anchor through the links that verified pages publish. A data point is verified when a verified page links to it, and confirmed when the link is reciprocal or two verified pages list it.	The method that verifies every data point.
