Re: change proposal notes-2 [1]

N.B. this proposal requires the following changes to the SKOS Core RDF/OWL description:

remove statements
{
skos:definition rdfs:subPropertyOf skos:publicNote.
skos:example rdfs:subPropertyOf skos:publicNote.
skos:scopeNote rdfs:subPropertyOf skos:publicNote.
skos:historyNote rdfs:subPropertyOf skos:publicNote.
skos:changeNote rdfs:subPropertyOf skos:privateNote.
skos:editorialNote rdfs:subPropertyOf skos:privateNote.
}

add statements
{
skos:publicNote a owl:DeprecatedProperty;
  dct:isReplacedBy skos:note.

skos:privateNote a owl:DeprecatedProperty;
  dct:isReplacedBy skos:note.

skos:note a rdf:Property;
  rdfs:label 'note'@en;
  skos:definition 'A general note, for any purpose.'@en;
  rdfs:comment 'This property may be used directly, or as a super-property for more specific note types.'@en;
  skos:example <http://www.w3.org/2004/02/skos/core/examples/note.rdf.xml>;
  rdfs:isDefinedBy <http://www.w3.org/2004/02/skos/core>;
  vs:term_status 'unstable';
  dct:issued '2005-09-29';
  dct:replaces skos:privateNote;
  dct:replaces skos:publicNote;
.

skos:definition rdfs:subPropertyOf skos:note.
skos:example rdfs:subPropertyOf skos:note.
skos:scopeNote rdfs:subPropertyOf skos:note.
skos:historyNote rdfs:subPropertyOf skos:note.
skos:changeNote rdfs:subPropertyOf skos:note.
skos:editorialNote rdfs:subPropertyOf skos:note.
}

N.B. this proposal also requires redrafting of the section 'Documentation Properties' from the SKOS Core Guide [2].

Mark [3] hasn't raised any objections to this change, although he has noted that the question of audience and function overlapping possibly arises for the properties skos:historyNote, skos:changeNote and skos:editorialNote.  Discussion of this issue is beyond the scope of the current review.

Ralph [4] hasn't raised any objections to this change.  Some responses to his comments below:

I intended to draft a section of prose for the SKOS Core Guide asap and circulate for comment.

I'll try to incorporate Stella's clarifying material into the new prose for the guide.  Also I'll expand the BSI reference.

I'm not sure what to say about this.  I think the notion of assigning 'stability' to a class or prop is a reasonable solution for the short term, but issues such as you raise have not been worked out.  Interesting to discuss further, but beyond the scope of the current review (something for VM :).

Cheers,

Al.
