Consider adding relationships between concepts #1

donmendelson commented 6 years ago

SKOS offers properties to define relationships between concepts: related, broader, and narrower. For example, "Sell Short" is related to "Sell Short Exempt", or perhaps the latter is a narrower concept.

One thing that I have not found a ready solution for is defining opposite concepts, such as "Held" and "Not Held". We could define a sub-property of "Related" for that purpose.

Concept relationship are indeed useful but would increase the initial complexity. Not sure whether to consider it from day 1, i.e. we would need to pin down a number of concepts to see relationships. In your example I would see "short selling" as the concept and exemptions to be a narrower concept (in the sense of sub-concept, i.e. exemptions may apply or not).

Opposing concepts would be related but is explicit modeling really useful? What about a property of a concept to express whether there is an opposing concept or not? Another example is the concept of a trade publishing instruction ("do not publish" vs "publish").
