ITU-T X.1528.1 PDF

This Recommendation on common platform enumeration (CPE) naming defines the logical structure of names for IT product classes and the procedures for binding and unbinding these names to and from machine-readable encodings. It also provides the requirements for well-formed CPE names (WFNs). This Recommendation also defines and explains the requirements that CPE naming implementations, such as software and services, must meet to claim compliance with this Recommendation.

As this Recommendation defines these specifications by listing the relevant clauses of the NIST Interagency Report 7696: Common Platform Enumeration Name Matching Specification version 2.3 and showing whether they are normative or informative, all other versions are out of the scope of this Recommendation as are all CPE specifications other than CPE Naming.
