Common use of The Metadata Model Clause in Contracts

The Metadata Model. We identify a type of relationships with primary role is-Described-by (IDB) which give to targets the semantics of metadata about the corresponding sources. In particular, we say that an IDB-source is a metadata object, or simply metadata, for the corresponding IDB-target. We expect IDB-targets to be documents, but do not require it. • We constrain IDB-relationships to be exclusive for their targets but repeatable for their sources. Accordingly, a metadata object can describe one and only one object but an object can have an arbitrary number of metadata objects. We also constrain IDB-relationships to preserve membership, so that a metadata object describes a member of some collection if and only if it is a member of some other collection in turn. • We say that a collection M is a metadata collection of type R for a collection C if M is an R-collection in the scope of C for some secondary role R of IDB. Specifically, (i) all the members of M are metadata for members of C, and (ii) M is metadata for C.
