XQuery unifies development for all tiers; database, content management, application logic, and presentation.
I started to mention this under the Cutting Edge Data Processing with PHP & XQuery post (which uses Zorba) but XQuery is important enough to list it separately.
In the draft Topic Map Tool Chain, I would put this under mining/analysis, but as was pointed out in comments, the mining/analysis phase can be informed by an ontology.
I would say “explicitly” informed by an ontology since there is always some ontology in play, whether explicit or not. (Formal ontologists, note the small “o” in ontology. An explicit ontology would have a name and be written <NAME> Ontology.
