TIAN

THIS IS A PROPOSAL

name

name not decided, see also identifiers

• TIAN Tango Info Audio Number
• TIAC Tango Info Audio Code
• TIAI Tango Info Audio ID
• TIAD Tango Info Audio ID

purpose

• identify a group of tracks
• ... tracks that are derived from same performance
• i.e. same in musical work, artist(s), time
• independent of knowledge about title of the musical work, artist name, time

grouping by meta data

currently tracks in tango.info are matched based on 4 track meta data fields:

• title
• orchestra
• vocalist(s)
• date

NOTES

• there are instances (examples?) of different performances which match by these criteria, e.g. 5 min later performed again.
  • a 5th field for disambiguation would be needed
• the track meta data is not fully provided for all. So the matching does not work as it could work with more meta data.

used for tango.info track based discographies

how to construct the id

• relation to matrix numbers?
• 02480003050123 and 02480003050222 tomas en vivo and de peliculas -> no matrix number
• "FrancCanar/1936-06-03/work:noches_de_amor" - kind of TIAN. Maybe can be

shortened.

• TIAN could be assigned like YYYYMMDD-XXX. For any Y,M,D not known special number range could be used. 1000 performances a day worldwide should be sufficient? Or XXX is alphanumeric. The order within XXX could reflect matrix order if a matrix number is known.
