问题
The rdfs file I'm want to use is cv.rdfs, I want to convert it to SKOS, so I can use it in Maui Indexer
I am a complete noob in the subject. Please help.

SKOS is for organizing concepts, and doesn't deal with properties, it seems, so there's a lot of information in the CV RDFS that doesn't really have a SKOS version. However, it's easy enough to define a mapping for the RDFS classes and generate some data using SPARQL. Here's a possible mapping:
- rdfs:Class maps to skos:Concept.
- rdfs:comments map to skos:notes.
- rdfs:labels map to skos:prefLabels.
- rdfs:subClassOf maps to skos:broader.
Using that mapping, we can write the following SPARQL which produces the resulting "SKOS document" (it's an RDF document using lots of SKOS vocabulary):
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix skos: <http://www.w3.org/2004/02/skos/core#>
construct {
?x a skos:Concept ; ?skosP ?y
}
where {
values (?rdfsP ?skosP) {
(rdfs:subClassOf skos:broader)
(rdfs:label skos:prefLabel)
(rdfs:comment skos:note)
}
?x a rdfs:Class ; ?rdfsP ?y
}
In the more human readable Turtle: (The awkward typo "Refernece" is in the cv.rdfs data.)
