Motivation

Carnegie just released their LOD, which was well-publicized in the LODLAM & GLAMwiki communities. This is important data for any music researcher.

Example record: http://data.carnegiehall.org/names/52002 (Rachmaninov) includes:

Matches to LCNAF, WD, DBpedia, MusicBrainz
gndo:professionOrOccupation (to lcMarRel: and to local http://data.carnegiehall.org/roles)
gndo:playedInstrument
schema:birthDate, schema:deathDate
dbo:birthPlace, dbo:deathPlace (to http://sws.geonames.org/: use rdfs:label and gn:parentCountry/rdfs:label)

Some stats (ask me for the queries):

Total persons: 95823
Persons with at least one match: 11863 (12.3%)
Breakdown of matches per target domain

11373	http://id.loc.gov/authorities/names (11.9% of persons)
 6582	http://dbpedia.org/resource          (6.9% of persons)
 3554	https://musicbrainz.org/artist       (3.7% of persons)
 3157	http://www.wikidata.org/entity       (3.3% of persons)

This query can be used to export data about Persons with no matches (omit "filter not exists" if you also want those with matches)

Check how many of Carnegie's not-yet-matched Persons are found in LOD. I tried to match the first few:

http://data.carnegiehall.org/names/36266 Eleanor Calhoun: no WD, no VIAF
http://data.carnegiehall.org/names/7716 Jacek Zganiacz: no WD, no VIAF
http://data.carnegiehall.org/names/42166 Michael Tolomeo: no WD, yes VIAF (ISNI & FR BNF, not matched)
http://data.carnegiehall.org/names/66372 Carla Khilstedt: no WD, no VIAF
http://data.carnegiehall.org/names/101913 Joseph Eunkwan Choi: no WD, no VIAF
http://data.carnegiehall.org/names/19566 Gary Mayer: no WD, maybe VIAF (DE GND undifferentiated name, i.e. not useful)
http://data.carnegiehall.org/names/19222 Ellen Margrete Flesjo: no WD, yes VIAF (NO BIBSYS & DE GND undifferentiated, not matched)

Note that the data.carnegiehall.org/names/ namespace also includes groups/ensembles -- for this reason, I've suggested a different label for this property, "Carnegie Hall entity ID". Many of the ensembles are also not found in LOD:

http://data.carnegiehall.org/names/25679 Volpe Symphony Society of New York (an interesting early example of a training orchestra, similar to present New World Symphony): no WD, no VIAF, no LOC
http://data.carnegiehall.org/names/54178 New York Symphony String Quartet: no WD, no VIAF, no LOC

It seems Carnegie got lots of people that are missing in the world-wide LOD. This means both that matching won't be very profitable, and also an opportunity to create such people in the world-wide LOD. VIAF mostly has records for people who PUBLISHED music or about whom books were published. So even very important performers may be missing from LOD! --Vladimir Alexiev (talk) 09:24, 23 June 2017 (UTC)[reply]

@Vladimir Alexiev: What's the meaning of the abbreviation "LOD"? Can you edit the description to make it clear? ChristianKl (talk) 11:46, 23 June 2017 (UTC)[reply]

Agree with @Rhudson: who is Carnegie's Manager of Archives. But changed entity->agent since in WD entity means "anything".

@Rhudson: the large number of entities that are not found in any of WD, VIAF, LOC means you need to make a decision: are most/all of them "notable enough" to be recorded in WD? And do you have enough data about them? WD is fairly lax about notability but for each set of data, there needs to be an interested community behind it --Vladimir Alexiev (talk) 19:23, 25 June 2017 (UTC)[reply]

I think Carnegie Hall is a serious and public source and thus the entities are notable according to our notability policy. ChristianKl (talk) 18:52, 26 June 2017 (UTC)[reply]

Support - Name change to "entity ID" justified, and a good data set to work with. -- Fuzheado (talk) 11:29, 1 July 2017 (UTC)[reply]

Support. This looks like a rich data set, I can imagine many cultural heritage projects being able to reuse this data. YULdigitalpreservation (talk) 13:03, 5 July 2017 (UTC)[reply]
