A.6.3.RT.OE:10 - Architectural Rationale

Reasoning and construction can proceed through expressions. A common part can join relations from different groupings; a delimiter can preserve a permitted operation; a temporal reference can coordinate signs in action. These contributions explain why semantic content and the means of using it belong in the same design question.

A.6.3.RT governs carrying content through a representation change. This Method develops the construction of the usable expression itself, including a first expression for a partial construction under available rules. The subject Method still supplies geometry, arithmetic, rhythmic composition or another operation performed with it. Construction of the expression and production of a subject result may alternate within the same work.

E.5.2 keeps interpretation portable across notations. C.37 helps choose representations for a use, and C.2.8 characterizes recoverable structure for a recipient. The present contribution is how to arrange the content so the selected operation can be performed. Designing notation rules and teaching their use remain further Methods within the notational repertoire.
