This blog post from "Voyages of the Semantic Enterprise" discusses the following issues and invites feedback: The SKOS-XL extension to the W3Cs SKOS standard for vocabulary management adds flexibility in how you track concept names, but it adds complexity and potential confusion that are rarely, if ever, worth it. Without a doubt, these issues play a role in the fact that while the use and tool support for SKOS is growing, there are few if any tools for SKOS-XL or published SKOS-XL vocabularies. An even more important factor is the lack of compelling business value that would justify SKOS-XL complexity.

- Knows Simple Knowledge Organization System, or SKOS (2009), an RDF vocabulary for expressing concepts that are labeled in natural languages, organized into informal hierarchies, and aggregated into co
- Knows SKOS eXtension for Labels, or SKOS-XL (2009), a small set of additional properties for describing and linking lexical labels as instances of the class Label.
- Understands that in a formal sense, a SKOS concept is not an RDF class but an instance and, as such, is not formally associated with a set of instances ("class extension").
- Understands that in contrast to OWL sub-class chains, hierarchies of SKOS concepts are designed not to form transitive chains automatically because this is not how humans think or organize information
- Understands that SKOS can express a flexibly associative structure of concepts without enabling the more rigid and automatic inferences typically specified in a class-based OWL ontology.
