  1. MDMI – Technical Overview

  2. What is MDMI? • MDMI is the OMG’s Model Driven Message Interoperability standard. It is an approved OMG Standard. • MDMI is a technical interoperability standard: MDMI is used to move information in one file format into and out of any other file format that uses the standard. • MDMI does not replace any existing industry standards. It uses and enhances existing standards in solving the problem of exchanging electronic information. • For healthcare, MDMI is an open source project in OHT and is a sub-project within the OHT MDHT project. The OHT MDMI project contains software (Editor (Design Time) and Runtime), input for the model (MDMI Healthcare Referent Index), and use of the model (MDMI maps).

  3. Requirements for MDMI Standard • Must incorporate and leverage existing and future industry standards • Re-engineering any legacy system is a non-starter. • Must deliver high quality • Must add business value: • Lower the expertise and time to implement solutions. • Quality of information exchange is higher. • Dramatically lower the cost and time to solution for change.

  4. MDMI – Technical Approach • MDMI is a different approach for information exchange between two parties. Instead of mapping A to B, MDMI solves the problem with two independentmaps.

MDMI Referent Index MDMI Referent Index Webster’s Dictionary Similarities • Business Element is equivalent to a word • The meaning of a Business Element doesn’t change • Business Elements are not deleted • Adding a new Business Element is not difficult and doesn’t impact other words. • Business Elements have synonyms. Differences • A Business Element has one meaning, and only one meaning • There is only one Business Element for a term (semantic clarity). • There are near-synonyms. is Equivalent to
