Hi Armando,


You may want to have a look at the SKOS reference - http://www.w3.org/TR/skos-reference/#xl

In particular Section B.2.4.1 (and less relevant for your issue: B.3.4.2)


Kind Regards,

Subject: identity of SKOSXL labels


Dear all,


suppose in SKOS I have:


mythes:C1  skos:prefLabel “foo”

mythes:C2  skos:altLabel “foo”


In SKOSXL, should I have something like:


mythes:C1  skosxl:prefLabel mythes:foo

mythes:C2  skosxl:altLabel mythes:foo 

mythes:foo skosxl:literalForm “foo”


or like this? :


mythes:C1  skosxl:prefLabel mythes:foo_1

mythes:C2  skosxl:altLabel mythes:foo_2

mythes:foo_1 skosxl:literalForm “foo”

mythes:foo_2 skosxl:literalForm “foo”



in other words, is SKOSXL enforcing in any way that concepts which are expressed through same lexicals, should have in any case their own labels for them or, on the contrary, a same label should be used…or these is no indication about that?


In  <http://www.w3.org/TR/skos-reference/skos-xl.html> http://www.w3.org/TR/skos-reference/skos-xl.html there is no hint about that, but I almost recall that I read/heard somewhere that the skosxl reification of the labels is *not* meant to “unify” labels with identical literalForms under a same URI, thus the general rule is to use in any case a different label URI for each concept.


Could anyone shed some light on this? (and, in case, point me to the appropriate link if there is any…)






P.S: in the example, I put a prefLabel for C1  and an altLabel for C2, but assuming the specific properties being used do not affect the answer to my question, so it could be skos:***Label. Pls let me know if this matters anyhow.
