This is a bit of a geeky thread, so please ask for clarifications if we forget to explain an acronym or library jargon...
We'd like to link the data created about people, plays and other works, runs of performances, genres, etc to other datasets. This might be relatively easy for works, but would be a lot harder for people (which 'Mr Smith' do you mean?). Ideally, we'd be able to crowdsource the process of linking or verifying computational links to other datasets.
To make a start, here are some projects with relevant data or identifiers:
The original Ensemble at NYPL http://ensemble.nypl.org/
Ensemble at Yale (historic programmes from performances at Yale) http://ensemble.yale.edu/#/
There was talk of a UK version of AusStage but I'm not sure if that went ahead.
Theatricalia has 'data for all RSC productions since its foundation in 1879, all Birmingham Repertory Theatre productions up to and including 1971 when it moved to its current location in Centenary Square, the wide variety of productions held by the University of Bristol Theatre Archive' https://theatricalia.com/about
ISNI is 'the ISO certified global standard number for identifying the millions of contributors to creative works and those active in their distribution, including researchers, inventors, writers, artists, visual creators, performers, producers, publishers, aggregators, and more' http://www.isni.org/
And then there's dbpedia, wikidata, etc...
Are there any quick wins? What about longer term tasks?
