.. IFD describes objects from what they are, independent of use and time, and not from what they are named or classified as.

Conceptual, because…


IFD describes an concept by relating it to other concepts

IFD includes properties and type values for concepts

concepts can be referred to, though globally unique IDs

Adding semantic from ontologies enables:

Two way links between different sources of knowledge Language independent interlinking of knowledge Linking of knowledge to material, products, elements... Multiple views to the same knowledge ”Context sensitive” knowledge (wisdom)
