RE: [ALL] agenda 25 Sep telecon - 1500 UTC


as well as Michael, I already posted my review mentioned in the point one on the agenda, see [1]. There was also an update I made in the Vocabulary Management part of the F2F agenda [2] on last Tuesday, so the excerpt in the telco agenda does not completely reflect the current state...

3. SKOS - see

Amsterdam agenda topic: "Label relations" (Guus) 
-- Issue-26: RelationshipsBetweenLabels (

ACTION: Guus to move ISSUE-26 forward [recorded in]

ACTION: Guus to post user experience reports for ISSUE-26 [recorded in]

ACTION: Alistair to state the difference between the two flavours of the SimpleExtension proposal for issue 26 [recorded in]

For discussion on the telecon, from

   Relevant issue:
    * [ '''Issue-26 - 
      RelationshipsBetweenLabels''' (open)]
    * Issue: SKOS allows to represent semantic relationships
      (broader, related) between concepts. It also allows
      to represent relationships between concepts and labels
      (prefLabel, altLabel). However, there is nothing proposed
      in SKOS to capture links between labels themselves, a
      configuration which sometimes happens in concept schemes.

   Required background reading:
    * [ 
      SkosDesign RelationshipsBetweenLabels]

   Three options will be discussed in Amsterdam
    * [ 
      Alistair's "Minimal Label Relation" proposal]
    * [ 
      Guus "Simple Extension" proposal]
    * [ Guus "remove range 
      restriction for skos: prefLabel" proposal]

Amsterdam topic "Labeling properties" (Alistair)

For discussion on the telecon, from

 Relevant issue:
  * [ '''Issue-31 - BasicLexicalLabelSemantics''' (open)]
     * Issue: Can a resource have two "preferred lexical
       labels"? Can a lexical label be both "preferred" and
       "alternative" for the same resource? If a lexical label
       is "hidden", can it also be "preferred" or "alternative"
       for the same resource?  ...
 Proposed solution:
  * [
    Alistair, 2007-06-26]: Alistair proposes a section of
    the draft SKOS Semantics as a resolution for Issue 31 --
    "This proposal deals with the intuitive semantics of
    'preferred', 'alternative' and 'hidden' at the syntactic
    level, which avoids complicated semantics conditions and
    allows for error-tolerant strategies to be defined."

Amsterdam topic "Semantic Relation Properties" (Sean)

ACTION: Sean to prepare readings and discussion topics for Semantic Relation properties [recorded in]

Amsterdam topic "Concept Semantics" (Antoine)

ACTION: Antoine to make wiki page or list posting summarizing issues for "Concept Semantics" [recorded in]

Amsterdam topic "Drawing the picture" - no discussion leader yet

ACTION: Guus to email a proposal to the list about Issue-36 ConceptSchemeContainment [recorded in]

 Problems to discuss:
  * Are relationships part of a concept scheme?
  * Are the concepts part of a concept scheme?
  * Capture underlying intuitions: UML diagrams? Blobs and lines?
  * What do we mean by "containment", "aggregation"...?
  * Are relationships of a concept somehow part of the concept?
  * Can concepts "exist" independently of a scheme?
  * Goal: see how things fit together in the larger picture.
 Relevant issues:
  * ISSUE-36 - ConceptSchemeContainment (open)
  * Guus thoughts on ISSUE-36:
  * Alistair: useful for ISSUE-36?
  * bs8273 - UML diagrams available?
  * Elisa/Clay/Ed/Jon: OMG, ISO 1087...?
