IEFRA2 — Definition of RA goals

1.6.2 Definition of RA goals.
I suggest you start with a definition based on a US DoD definition used in the DIDO-RA for Reference Architecture.

A Reference Architecture (RA) is defined as a set of goals:
● Provide common language for the various stakeholders
● Provide consistency of implementation of technology to solve problems
● Support the validation and comparison of implementations
● Encourage adherence to common standards, specifications, and patterns
