Notes

1.“A view belongs to a particular Architectural-Description. A viewpoint captures the Rules for constructing and analysing a particular kind of view. It is a template for a view and can be reused across many Architecture descriptions. View Type was considered as an alternative term for viewpoint because of the strong analogy of view and viewpoint to instance and Type; but we chose "viewpoint" because of its use in existing Standards and the Requirements analysis literature. Separating the two Concepts is important for writing Standards, although not essential if one's Scope is simply the description of a single System.“

2.“The key Idea is that a viewpoint identifies a set of concerns about an Architecture, and how the Architectural-Description will address these concerns, in terms of languages and notations, models and analytical techniques, methods, etc.”

3. Planguage is one of many possible basic Resources for constructing a viewpoint. Planguage templates, for Requirements or design, are specific examples of practical viewpoints.
