MS purls are broken

[Hannah-Doerpholz]

I noticed that the MS links are broken (e.g. https://ontobee.org/ontology/MS?iri=http://purl.obolibrary.org/obo/MS_1000572). They are supposed to resolve to Ontobee. According to the Ontobee issue tracker, the issue lies with the MS links OntoZoo/ontobee#203 (comment) . I have also opened an issue on the GitHub repository for the MS ontology (HUPO-PSI/psi-ms-CV#259 (comment)) but I am not sure if the purls are something that need to be handles by the MS people or by the OBO Foundry.

Thanks for the detailed report.

Yes, the PURLs are configured in this repository, specifically in this file: https://github.com/OBOFoundry/purl.obolibrary.org/blob/master/config/ms.yml

I believe that the PURL system is functioning correctly. http://purl.obolibrary.org/obo/MS_1000572 redirects to Ontobee https://ontobee.org/ontology/MS?iri=http://purl.obolibrary.org/obo/MS_1000572, and I can download an OWL file from http://purl.obolibrary.org/obo/ms.owl. Since OLS can display this term, it must be able to fetch and process ms.owl: https://www.ebi.ac.uk/ols4/ontologies/ms/classes/http%253A%252F%252Fpurl.obolibrary.org%252Fobo%252FMS_1000572?lang=en. I think the problem is with Ontobee.
