Guus: I've started this, hope to post a draft response by the end of the week
... a short summary of my comments: (a) the number of additional features provided is useful for characterizing SKOS properties
... (b) none of the documents are really accessible to a typical SKOS reader
... (c) the documents appear to be very biased toward the -DL version of the language

Ralph: I would concur with all three

Alistair: me too

<TomB> +1 on Guus's comments

"Standard" vs. mapping relationships in Primer

-> "Mapping" vs "standard" relationships [Tom 2009-01-13] start of thread

<TomB> Antoine's message on 27 January

Antoine: it's still difficult to evaluate; the discussion is around one sentence
... whether to keep or remove or change this sentence
... the discussion is still ongoing
... but the conclusion will be easy to write once we agree

Tom: the Primer currently in queue to be published seems to recommend the use of mapping relationships when enriching a vocabulary
... the minimal approach taken in SKOS Reference makes a simpler distinction; it says only that you should use standard relationships when talking about relationships within a concept scheme and mapping relationships between schemes
... the current editor's draft of the Primer suggests using mapping relationships when someone other than the owner is making relationships within a concept scheme
... this appears to me to be a bit of an inconsistency
... for the next version of the Primer it would be good to decide this
... "enrichment within a concept scheme" is one suggestion
... I would accept a minimum solution
... if Antoine's point could be articulated in a way to satisfy everyone, I see some value in it

Ed: what's the one sentence?

<TomB> SWD/SKOS/primer/primer-20090113

Antoine: the discussion started with a sentence about enrichment

Tom: see end of section 3.1
... "However, the use of mapping properties might also be appropriate in cases where someone other than its owner needs to enrich the semantic relationships within a particular concept scheme."
... the question is whether this goes beyond what SKOS Reference says

Guus: what would be the problem in deleting the sentence?

<aliman> Key section from SKOS Reference, section 10.6.1. Mapping Properties, Semantic Relation Properties and Concept Schemes, """By convention, the SKOS mapping properties are only used to link concepts in different concept schemes."""

Guus: we could see what practices are adopted
... this doesn't sound like a necessary statement for a Primer
... but could agree that this sort of hint is not appropriate for a Primer
... it's not a strong hint anyway; I'd feel more comfortable removing it.
... if we had more time, I'd hope the document would be shorter :)
... would dropping this sentence remove the problem?

Alistair: think so

Tom: looking at the preceeding sentence ...
... the paragraph before isn't necessarily the best wording but I don't have anything better to suggest right now

Guus: I suggest we drop the 'However ...' sentence from the Primer

Antoine: OK with me

Alistair: OK to drop

Tom: OK to drop

ACTION: SKOS Editors drop "However, the use of mapping properties might..." sentence from the primer section 3.1 [recorded in http://www.w3.org/2009/01/27-swd-minutes.html#action10]

[adjourned]
