Import skos vocab in Omeka-S


I just tried to import the skos vocab to describe links between three different concepts ( I need the classes skoas: broader/narrower/broaderTransitive and narrowerTransitive. Here is the page i filled in and the mistake message above:

No class or properties found. Are you sure you used the correct namespace URI ?
I filled in this way :

Vocabulary URI :
Préfix : SKOS
Spacename URI :
Label : SKOS

I am a beginner in Omeka-S , so sorry in advance if is an easy mistake to correct but I cannot find solutions.
Many thanks,

This should work:

Vocabulary URL:
Prefix: skos
Namespace URI:
Label: SKOS

It works !
thanks a lot

I managed to import ontology skos but it is incomplete, there are only 18 properties out of 28.
For example, I do not see the following properties: skos: altLabel, skos: prefLabel …
thank you in advance for your help


surprising then I have the 28 properties available. Sorry I cannot help you further.
