Simple Knowledge Organisation Systems (SKOS)
I will continue to persue my little acronym project, but it is possible that it will eventually simply map into a Simple Knowledge Organisation Systems (SKOS) language. Oversimplifying, SKOS provides capabilities for defining controlled vocabularies.
From the Wikipedia:
SKOS Core  defines the classes and properties sufficient to represent the common features found in a standard thesaurus. It is based on a concept-centric view of the vocabulary, where primitive objects are not terms, but abstract concepts represented by terms. Each SKOS concept is defined as an RDF resource. Each concept can have RDF properties attached, including:
- one or more preferred index terms (at most one in each natural language)
- alternative terms or synonyms
- definitions and notes, with specification of their language.
Concepts can be organized in hierarchies using broader-narrower relationships, or linked by non-hierarchical (associative) relationships. Concepts can be gathered in concept schemes, to provide consistent and structured sets of concepts, representing whole or part of a controlled vocabulary.
These features represent the stable part of SKOS Core. Other elements of the vocabulary are still considered unstable.
Acronyms might fit in as "alternative terms", but I am not so sure about that. To me, alternative terms should be full-fledged, first-class terms and not abbreviations or acronyms.
In any case, SKOS will be on my future reading list. For now, I want to keep the acronym project as simple as possible.
