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).
