Semantic webs must procure understanding by presenting explanatory facets.
Facets are aspects, topics, systems, contexts, scopes, showcases, domains or groups, which are
- consist of implicit groups of components (and their interrelations)
- can be reified, e.g. the facet/aspect "safety" can have the properties "Has priority::Top" and "Is assigned to::Mark".
For example, the facet/aspect "safety" of a car cannot be instantiated like "This is safety A and that is safety B.". But the facet/aspect "safety" can enfold the instantiations of seatbelt model 24 and airbag RT45.
Components have a default component type in accordance with general common-sense understanding to be used if “met-on-the-floor”.
Components can bear several different component types in different constituent facets, i.e. they assume different roles in different facets.
