SKOS encoding of local (JDX) concept schemes

[stuartasutton]

Controlled value spaces from entities such as ONet and HR Open Standards should be modeled as RDF using W3C's Simple Knowledge Organization System [SKOS]. I have illustrated use of SKOS below with a single ONet concept--"Logistics Manager". Note that SKOS is comprised of two straight forward classes: skos:ConceptScheme and skos:Concept. Each concept declares itself to be a member of the concept scheme via the propertyskos:inScheme. Most ONet concept schemes are flat enumerations. However, where there is hierarchical structures, SKOS provides two properties for relating broader and narrower concepts --skos:broader and skos:narrower...pretty simple but powerful.

SKOS is also extensible using any RDF property. To illustrate, I used jdx:jobTitle to add an array of example job titles from ONet for the concept "Logistics Manager". With the exception of the ONet concept schemes --"knowledge", "skills", "abilities"-- all enumerations in ONet can be locally encoded using SKOS. Code lists from HR Open Standards can also be encoded using SKOS.

Note the use of the property jdx:source to create a digital thread that links this SKOS concept back to the ONet source.
