SPECTRA — SV1 profile must avoid string typed attributes whenever possible

SPECTRA feedback 30-04-2025
String-typed attributes are used in SPECTRA SV1 in lieu of relationships which are often missing in existing SysML models, but are deemed necessary as core assertions for cyber. Examples of this are tags key, assembly key and group key in Information Pathway stereotype. While SPECTRA uses these tags to accommodate existing models and minimize the cost of adding SPECTRA annotations so that core assertions can be extracted, the practice of using matching string types tags may impede automatic testing of the elements and relationships.
