I hardly see how you can define in a RDBMS that a resource that both have an engine and four wheels should be seen as a car.
Without going into a nightmare of unbearable SQL...
- zozbot234 4y agoThe SQL for describing "resources that contain other resources" gets a bit unidiomatic, but defining a query for those that have e.g. an engine and four wheels is quite easy. Then you can add that as a custom view, so that your inferred data is in turn available and queryable on an equal basis with raw input to the knowledge base.
- lolive 4y agoSure. But maintaining the coherence between your business data model definitions and their implementation in the RDBMS can quickly become a massive headache, don't you think?
