  1. Project Definition

3.a. Project Scope

This project will create a functional specification for transformation services with exemplary mappings using storyboards developed by the SOA Working Group, the interested parties of the Project, and co-sponsor WGs of this project. The project will create story boards that use aspects of 1) the current versions of HL7 Standards of V2, C-CDA, and FHIR, and 2) new information models such as CIMI and realm specific examples such as the FHIM. Artifacts for the Storyboards will be produced at a logical level to ensure traceability (iso-semantic relationships) between data elements as well as identify semantic gaps.  The project will use existing open source software.


The project addresses a major requirement of the HSSP Transformation Service. The scope of the project is limited to the exchange of data between a source and a target where the source and target include different HL7 Standards used to define or exchange information. The project will identify what semantic concepts can be exchanged accurately, where there are potential issues, and identify what cannot be exchanged.   The project scope is limited to an informative specification as SOA group does not have the responsibility to resolve any issues in the underlying standards. The project will provide input to relevant content working groups who can decide if they want or need to address such issues.  The project will not attempt to harmonize standards.


The project will collaborate with other HL7 Projects, particularly in the area of testing use cases and storyboards they have developed. As an example, to enable and test standard transforms across these product lines, the project will specify the syntactic   rules and relationships for assigning   security labels to HL7 v2, CDA, or FHIR content . This work will be based on the HL7 Privacy and Security Healthcare Classification System (HCS). Another component of this particular use case will be to provide recommendations on harmonizing a repeatable approach for cross-paradigm interoperability based on previous work efforts of the SOA WG and the CBCP WG.

3.b. Project Need

Since the publication of the previous Cross Paradigm Immunization Work, the business needs and the complexity for interoperability between diverse HL7 standards has increased. Examples from members of the SOA WG, co-sponsors, and interested parties attests to the need to expand the scope.


Examples of the need driven by business issues are CMS Accredited Care Organizations activities, emerging needs patient centric care plans and care coordination across different healthcare organizations required by the Veterans Administration, and the realization that the different HL7 formats, which have been implemented with significant investment, will need to be semantically interoperable.



The previous Cross Paradigm Interoperability work demonstrated the feasibility, agility, and value of a Model Driven Architecture (MDA) approach using an open, standard Platform Independent Model (PIM). This approach complements the HL7 Service Aware Information Framework (SAIF) for developing both logical and computable interoperability artifacts.




3.c. Security Risks

Will this project produce executable(s), for example, schemas, transforms, style sheets, executable program, etc.  If so the project must review and document security risks. Refer to the Cookbook for Security Considerations for additional guidance, including sample spreadsheets that may be used to conduct the security risk assessment .
