Hi Federico and hi all, FRBRoo https://en.wikipedia.org/wiki/FRBRoo - today at version 2.0 - introduced the concept of "Classes of Work" for the Performings Art. You can find the text of guidelines on IFLA website http://www.ifla.org/node/9453 and a cheat sheet on CIDOC website: http://www.cidoc-crm.org/frbr_graphical_representation/graphical_representation/expression_manifatation_added_value_chain.htmlas you can see, the relations "performed" and "was performed in" are expecteded between "Performance" and "Performance plan". A quick and clear explanation of this concepts is here https://www.researchgate.net/publication/252888336_FRBR_OO_a_Conceptual_Model_for_Performing_Arts (in particular, pp. 6-9). In conclusion, I think that the property "performance of" is necessary but, first of all, it's need to define when to use this property. Happy New Year! Chiara

At BEIC, to test the Wikidata ontology and the feasibility of collaborations on music data, I was assigned a seemingly simple test: add in Wikidata all the data contained in https://en.wikipedia.org/wiki/Brown_Sugar_(The_Rolling_Stones_song) .
Turns out things are not so simple:
- the Wikipedia articles, from an FRBR (https://en.wikipedia.org/wiki/FRBR
) perspective, often mix multiple levels or even all of them (song, recording, album, single, edition of the single) which on Wikidata need to be separate items, but the split is not obvious: https://www.wikidata.org/wiki/Special:WhatLinksHere/Q21887964 ;
- I was unable to properly add information on per-country hit list
position.
Please give a look to the items I linked, to my https://www.wikidata.org/wiki/Wikidata:WikiProject_Music updates and to the open questions I added in https://www.wikidata.org/wiki/Wikidata_talk:WikiProject_Music .
In particular, I think librarians will be interested in this proposal for a "performance of" property, which (like the existing "edition of" property) could benefit from being framed in a FRBR perspective by someone more versed in FRBR. https://www.wikidata.org/?diff=287456096
