Rework index/core Concepts to have all necessary information for concepts

[marcofranke]

For each concept, we need at least the URI of the concept and the label available. The label is necessary to define the search term for a given concept. To support more than one language we would need more than one label like in index/core properties:

The example demonstrates to valid concepts URL. Without a label, the search term is not derivable for both.

As said (already multiple times)!!!

The index can only retrieve what is stored in the triple store .... the pre-requisite is a clean core ontology where

the base classes for both "classes" and "properties" out of the Nimble-Core-Ontology is used throughout the A-Box and T-Box.

@marcofranke Please name the basic concepts out of the Nimble-Core ontology for properties and classes!
