Motivation
editWorldCat Entities (Q112122720) is a linked data service from OCLC for persons, works, and places, funded in part by a grant from the Mellon Foundation, in partnership with an advisory group of 28 libraries. The system allows users to browse through different languages and explore the way each entity links to other external vocabularies and authority files for further context.

Nice! @UWashPrincipalCataloger, Pteropotamus, Emwille, Sheilatb, Jimfhahn, Kiwigirl3850:
Can someone provide some info about it? How many items? What does it link to? Is there a dump or SPARQL endpoint?
- I've looked but these questions are not answered by https://www.oclc.org/en/worldcat/oclc-and-linked-data/worldcat-entities.html
- https://id.oclc.org/worldcat/entity/E39PBJc83fJFkMYcyckKjjPJDq.html is a substantive entry, links to 24 datasets (VIAF, all its components, etc)
- A lot of the descriptive data is ingested from WD, but still knows a lot less than Vasil Levski (Q318461) (eg birth place but not death place, and not any death circumstances)
- Of course, it's still very new! Inception: 24 May 2022
From URLs like this it's obvious that it's PARTLY driven by Wikibase:
- https://id.oclc.org/worldcat/entity/Q5
- https://id.oclc.org/worldcat/entity/P225
- https://id.oclc.org/worldcat/entity/P26

- I was on the advisory board while it was being developed from Feb 2020 - Dec 2021. Part of my work on the advisory board was evaluating the interface and APIs.
- The EMI service has people and works as their focus; but places also hung off of those entities.
- The data is enriched with Wikidata and the initial system began as wikibase. Though I understood that much of the wikibase code for the front-end is completely replaced with an OCLC standard front end stack. I think they used Amazon Neptune for the SPARQL.
- Eventually API access will be available, I did evaluate a version of the API where we could use SPARQL statements against the service. I think that the API will not be a free service though.
- As for the number of entities in the system -- OCLC made use of previous experimentation with their Work IDs from worldcat.org. According to a 2014 presentation there could have been ~360 million work IDs then: https://www.oclc.org/research/events/2017/12-12.html
- OCLC's worldcat is made up of 2 billion items though there is not a 1:1 match of work to items. Rather many items relate to a single work. OCLC identities represented people identifiers and their associated works: http://www.worldcat.org/identities/
- I also believe this infrastructure (OCLC EMI) to be a place for sustainable access to work and people IDs for bibliographic data. There is alot more that I'd like to know about the service, too -- but I'd be inclined to await a webinar from OCLC with more concrete details about numbers of entities and API access plans.
