Issue 7: How to model relation between physical carrier and conceptual objects
There are two solutions: Either an object is instantiated multiply as physical object and conceptual object, or a specific link is introduced. This implies how to model a physical documents class (e.g. books) (former issue 25).
In scope: Introduce a new entity: Information Carrier to replace Iconographic Object. The link for this would be "is carrier of (is materialized by)" which points to Information Object.
Resolved by creating new entity: Information Carrier to replace Iconographic Object (E23) and to add a property "is carrier of (is materialised by)" from Information Carrier to Information Object (E73). E23 to be deleted. E23 was not regarded a subclass of E73.
