Hi Armando! > there is no enforcement by SKOSXL and it's a modeler's choice. Yes, and I can see legitimate uses for both models: - shared Label: only when there's a logical and permanent reason why the two labels are the same. Then the maintenance of this shared label can be easier, because it needs to be done only once. - own (copied) Label: this is the usual case. Use when the literals are *incidentally* the same but may become different in the future It also makes the referential management of labels more difficult: if you delete a concept, you need to refcount before you can delete its labels. SKOS editors should enforce neither model. But could they support both? - When creating a new label, I think it's a stretch to ask the user "reuse a shared label?": just create an own one - RDF-native editors (like VocBench) may receive a SKOS file with shared labels... In that case I think keeping them shared is best. ---- I am not aware of any actual SKOS thesaurus using shared labels. But here's a related example: Getty has a peculiar internal organization: literals are shared between *languages* Lookie at the first 3 "Terms" here: http://www.getty.edu/vow/AATFullDisplay?find=rhyta&logic=AND¬e=&english=N&prev_page=1&subjectid=300198841 the string "rhyta" is actually shared between the languages en (English), el-Latn (Greek transliterated) and es (Spanish) in their database But of course when mapped to skos-xl, we had to unshare. Lookie here: http://getty.ontotext.com/resource/aat/300198841 Those 3 terms are mapped to different skosxl:Label nodes: skosxl:prefLabel aat_term:1000198841-en, aat_term:1000198841-el-Latn; skosxl:altLabel aat_term:1000198841-es Aye? PS: this is still under development, we know there are omissions and buggies. Eg skosxl:prefLabel are dumbed down to skos:prefLabel but skosxl:altLabel aren't
