UAF13 — Appendix B - Glossary - Change of ISO 42010 'Architecture Viewpoint' to 'Viewpoint'. UAF Actually 'Viewpoint' Has at Least 2 Meanings, Only 1 Defined

EA guide p 136 - Appendix B - Glossary - Viewpoint

This states that the ISO 42010 term 'Viewpoint is '“conventions for the creation, interpretation and use of an architecture view to frame one or more concerns” [ISO 42010] that governs the creation of views'

It then states that the UAF term 'viewpoint' is 'frames (to formulate or construct in a particular style or language) one or more Concerns. A Concern can be framed by more than one Viewpoint.'

1) the ISO 42010 term is 'Architecture Viewpoint' not 'Viewpoint' - this distinguises it from incorrect casual uses of 'viewpoint'.
2) If anyone sees 'Viewpoint' how will they know whether it's the ISO 42010 'viewpoint', the first meaning of UAF 'viewpoint' defined above or indeed the MODAF viewpoint which is used within the documents bit not defined anywhere?
3) If you modify the ISO 42010:2022 definition by appending anything it isn't then the ISO 42010 definition and shouldn't be labelled as such because it misleads. If you need to add notes use a footnote so that there is clear physical separation of what is a local annotation. Adding a description of relationships etc shouldn't be part of the definition of any concept - it should be atomic - it is an element in the 42010 conceptual model and describing the conceptual model shouldn't be in the table itself. Or create an additional 'Comments' column and move the non standard text there.
4) Until all references to (MODAF) viewpoint are removed the UAF cannot claim and a 'viewpoint' = ISO 42010:: architecture viewpoint because in many places in the text it isn't

Simnilarly for 'View' above - there is not such thing in ISO 42010 as 'View' - the correct term is 'Architecture View' because there are many casual and incorrect meanings of 'View' (as the UAF element is named)

This is a self-inflicted error - if the UAF stuck to the name and definition defined by ISO 42010 it wouldn't arise - there wouldn't be 2 (actually) 3 uses of 'viewpoint' with different meanings. That's the point of standardisation - only 1 term, 'architecture viewpoint', used throughout with the one consistent meaning.
