SYSML17 — Metadata, ArchitectureMetadata Incorrect - Metadata Applies to Architecture Description Not Architecture. ArchitectureMetadata duplicates Metadata in application to an AD

This is a consequence of the lack of differentiation within the UAF (and donor AFs) between 'Architecture' and 'Architecture Description'

Fig 9:122 Metadata.
Definition: 'A comment that can be applied to any element in the architecture. The attributes associated with this element details the relationship between the element and its related dublinCoreElement, metaDataScheme, category and name. This allows the element to be referenced using the Semantic Web.'

it is clear that this refers to 'architecture description' not 'architecture' e.g. the application of DCMI elements

It should therefore be 'applied to any element in the architecture description'

If Metadata is already defined as applying to an architecture description, how can ArchitectureMetadata specialise this and also be applied to the architecture description description - this is what Metadata does and as part of an AD which describes an architecture there is no need for 'ArchitectureMetadata'?
