CHMO has incorrect metadata

[cmungall]

OLS shows:

Ontology IRI: http://purl.obolibrary.org/obo/chmo.owl Version IRI: http://purl.obolibrary.org/obo/chmo/releases/2014-11-20/chmo.owl Ontology ID: chmo Version: 14-11-2019 Number of terms: 3084 Last loaded: Thu Jun 17 03:17:23 BST 2021

has obo format version 1.2

Problems:

• How can it have Version of 14-11-2019 and a versionIRI of 2014-11-20?
  • I suspect this is something to do with CHMO not including a versionIRI in its header and OLS caching old version?
  • The actual last release would 2019-11-14 (note OBO dates should ALWAYS be ISO 8601)
  • No idea where 2014-11-20, but this gives a mistaken impression CHMO has not been updated in > 7 years
• the 'has obo format version' field is not in chmo.owl
  • I suspect that maybe OLS has a pointer to the obo format version and this gets injected in the conversion?
• same with saved-by

It would be wonderful if OLS could add more metadata about provenance of the load to make debugging this kind of thing easier

@cmungall The version issue is fixed as far as I can see.

As for has obo format version comes from http://purl.obolibrary.org/obo/chmo.owl.

        <oboInOwl:hasOBOFormatVersion rdf:datatype="http://www.w3.org/2001/XMLSchema#string">1.2</oboInOwl:hasOBOFormatVersion>

and

    <owl:AnnotationProperty rdf:about="http://www.geneontology.org/formats/oboInOwl#hasOBOFormatVersion">
        <rdfs:label rdf:datatype="http://www.w3.org/2001/XMLSchema#string">has_obo_format_version</rdfs:label>
    </owl:AnnotationProperty>

saved-by comes from

<oboInOwl:saved-by rdf:datatype="http://www.w3.org/2001/XMLSchema#string">batchelorc</oboInOwl:saved-by>

also in http://purl.obolibrary.org/obo/chmo.owl.
