Hi Antoine, and all,

Could you verify that the below RDF is what is intended by your suggestions?

  oa:MotivationScheme a skos:ConceptScheme ;
    skos:hasTopConcept oa:annotating.

  oa:Motivation rdfs:subClassOf skos:Concept .

  oa:annotating a oa:Motivation ;
    skos:prefLabel "Annotating"@en .

  oa:editing a oa:Motivation ;
    skos:inScheme oa:MotivationScheme ;
    skos:broadMatch oa:annotating ;
    skos:prefLabel "Editing"@en .

  new:correcting a oa:Motivation ;
    skos:inScheme new:AScheme ;
    skos:broadMatch oa:editing ;
    skos:prefLabel "Correcting a Mistake"@en .

  new2:fixing a oa:Motivation ;
    skos:inScheme new2:AnotherSchemne ;
    skos:broadMatch oa:editing ;
    skos:closeMatch new:correcting ;
    skos:prefLabel "Fixing a Mistake"@en .

And to your comments...

The thought was that it would be easier to assert that the range of
oa:motivatedBy is a oa:Motivation, rather than any skos:Concept.  Also, as
below, they may not be in any Concept Scheme.  Unless there's a reason not
to, I think this would be good to keep.

Fixed in to-be-published revised draft.

Agreed, fixed this.

This, too, will be fixed and published very shortly :)
