What is the PBA ontology?

[bgyori]

Hello, looking at the content of Bgee, I was wondering, what ontology is PBA? The links out from specific pages like this link http://purl.obolibrary.org/obo/PBA_294022000 on this page https://bgee.org/?page=gene&gene_id=ENSG00000110881 don't resolve correctly. I couldn't find anything about PBA in registries like identifiers.org, OLS, etc. Thanks for your help!

Somewhere this discussion ended up on the OBO Foundry slack and I think the consensus was it means Primate Brian Atlas (https://bioregistry.io/registry/pba)
