The HL7 Version 3 Product Suite and Framework (abbreviated “HL7 v3″) is the “latest and greatest” HL7 standards foundation for clinical information exchange.

At the core of HL7 v3 is an abstract model dubbed the Reference Information Module (RIM). HL7 describes the HL7 v3 RIM as: “the combined consensus view of information from the perspective of the HL7 working group and the HL7 affiliates… the ultimate source from which all HL7 Version 3 standards draw their information-related content.”

The RIM, along with HL7 Data Types and Vocabulary Specifications are the foundation for all information modeling within HL7. The HL7 v3 Product Suite includes a wide range of foundation specifications and models that every HL7 v3 standard draws from. As such, in the words of HL7: “they are a ‘part’ of every HL7 Version 3 standard and have the same ‘customers’ as do the standards defined from them”.

The CDA standard, and CDA-derived standards (formally termed “implementation guides“) – such as C-CDA, which features prominently in the US Government’s Meaningful Use requirements – are all part of HL7 v3.

Deep technical expertise in any HL7 v3 standard requires a thorough understanding of the underlying HL7 v3 foundations.

It’s the view of CDA PRO, however, that a great deal of effective practical implementation work with the CDA and C-CDA standards – especially in an MU2 context – can be achieved with the support of the content and tools provided by CDA PRO, without delving into the HL7 v3 foundation materials.
