Types of References
Authoritative reference (AR):
- Meets the requirements for a prescriptive reference AND has an agreement between ISO and the owner of the referenced specification to ensure that the concept referenced shall not be changed without the agreement of the ISO.
Prescriptive Reference (PR):
- The concept embodied in that EDCS dictionary entry is the same concept as defined in a specification. The concept definition of the concept in the EDCS may be different from the definition in the specification because of modifications to either:
- Include missing (implied) context not present in the definition in the specification, or
- Match the style and structure of other concept definitions in this International Standard.
Informative Reference (IR):
- The concept embodied in that EDCS dictionary entry is either the same as or is derived from a concept defined in another document. In this case, the concept defined in the EDCS shall be defined by the meaning of the words used in the concept definition and shall not require any material from the cited reference for its understanding.
