=Medical Summary - Interoperabilty Specification and Implementation Guide Development=

Overview
The NHIN Exchange will develop one or more Interoperabilty Specifications which define specific instances of Medical Summaries which meet the various program and interoperabliity requirements established in the Requirements Definition activites.

C32 Harmonization Activites
HITSP/C32 draws from a variety of underlying standards and profiles. As such, the information needed by implementers to understand C32 and its requirements are spread across a number of discrete documents, as illustrated below. While this approach can foster efficient standards development activities and a consistent architecture, it has created quite a bit of difficulty from implementers' persepctive. This project includes a number of activites intended to alleviate implementer difficuties, they include:


 * 1) **Issue Identification and Resolution** - C32 V2.5 was published in July of 2009. Since that time, various errors and issues have been identified within C32 and associated HITSP documents, as well as within its layered constraints. This project will collaborate with IHE, HL7, and former HITSP members to document and address these issues. A list of issues and their status can be found on the C32 Issues Page.
 * 2) **C32 Model Development** - We are collaborating with the Model Driven Health Tools (MDHT) project to create a UML model from the existing document based specifications contained in the diagram above. A model based specification will afford capabilities which unavaialble in the current document based format. For example, the model can be used to... Model development activities and status are maintained on the C32 Model Page.
 * 3) **C32 Interoperablilty Spec and Implementation Guide Deveopment** - Output from Issue Resolution and Model Development will feed the development of an Implementation Guide for C32, as well as for the NHIN Exchange C32 Inpteroperability Specification(s)
