Vaccine Ontology

[09:16] Tiago Lubiana: Now the scraper has run, here is the auto mappings and suggestions for the Vaccine Ontology:

[09:19] Asiyah Yu Lin - NIAID: Tiago, we could work with you on VO and Wikidata. I will connect you with Oliver He.

[09:20] Tiago Lubiana: Thanks Asiyah! I set up the mapping infrastructure, but I cannot actually work on that for the moment. Hopefully in the future!

[09:50] Tiago Lubiana: I don't know if I understood it completely the question, James, sorry!

Here are the Wikidata dumps:

Wikibase has some different datatypes that might play the role of Literals:

[09:51] James Overton: No worries. Your answer was good! Thanks

Wikidata Channel

[09:51] Tiago Lubiana: (I do have to leave now, unfortunately, thank you for opening this space! We have a Wikidata channel in the OBO slack by the way, if anyone has other questions:


[09:52] Vincent Vialard:


[09:56] James Overton: This page discusss DBPedia and Wikidata, but I'm still a bit confused:
