ro.obo is highly incomplete

[matentzn]

There are a few things in RO that cannot be captured in RO:

• SubAnnotationPropertyOf axioms
• AnnotationPropertyRange axioms
• DLSafeRules
• SubObjectPropertyOf if they involve inverses
• Complex subClassOf axioms beyond OBO
• Complex disjoint class axioms
• Some OP characteristics, like IrreflexiveObjectProperty
• ObjectPropertyRange axioms with complex ranges
• DataPropertyRange axioms (?)

All in all there are 147 axioms squished into the owl-axioms header of ro.obo.

[matentzn]

There is a second problem here though:

owltools --use-catalog ro.owl --merge-import-closure -o -f obo ro.obo.tmp && mv ro.obo.tmp ro.obo

$ grep OMO_ ro.owl
    <!-- http://purl.obolibrary.org/obo/OMO_0002000 -->
    <owl:AnnotationProperty rdf:about="http://purl.obolibrary.org/obo/OMO_0002000"/>
        <obo:OMO_0002000 rdf:datatype="http://www.w3.org/2001/XMLSchema#string">PREFIX rdfs: &lt;http://www.w3.org/2000/01/rdf-schema#&gt;
}</obo:OMO_0002000>
        <obo:OMO_0002000 rdf:datatype="http://www.w3.org/2001/XMLSchema#string">PREFIX owl: &lt;http://www.w3.org/2002/07/owl#&gt;

        <obo:OMO_0002000 rdf:datatype="http://www.w3.org/2001/XMLSchema#string">PREFIX rdfs: &lt;http://www.w3.org/2000/01/rdf-schema#&gt;
}</obo:OMO_0002000>
$grep OMO: ro.obo
NO OUTPUT

In other words, the OMO annotations entirely disappear cycling through owltools.
