The iMDHT technical team

• Shared Technical Objective: Toolkit that lowers the bar and accelerates development of innovative applications

• Shared Vision – Model Driven Tools creating computable artifacts– Community Development

• Open Standards• Open Source

– Service Oriented Architecture; necessary to address a complex healthcare eco-systems.

iMDHT Software ComponentsSoftware:

– MDHT (OHT project). Used by ONC and NIST in achieving Meaningful Use. Funded by IBM and VA. Information modeling tool that generates computable artifacts for developers.

– MDMI (OHT project). Approved Object Management Group Standard. Implementation Guide being developed by the HL7 SOA Cross Paradigm group. Transformation modeling tool that generates computable artifacts for semantic interoperability.

– DTS (OHT project). Terminology services technology used by VA and IHS. Terminology repository and modeling tool that manages industry standard and proprietary terminologies, and supports services (and computable artifacts) required for semantic interoperability.

– Socratic Grid (Github Project). Thought leaders in military and business services healthcare software. A platform for real-time analysis services using inferencing technologies.

The integrated toolkit is achieved by using open standards and computable artifacts.

iMDHT is adaptable and extensible

• New APIs for innovative applications: Sharp, Meaningful Use n+1, and others

• Dynamic Querying across Distributed Systems • Innovative terminology efforts: CIMI, Legos, and

others • New business services• Extensible to workflow processes: care coordination

New applications to address the above can be accelerated with iMDHT and extensions to iMDHT

Value• iMDHT

– Is pragmatic. (See Immunization Use Case Proof of Concept)– Provides a simplified interface for any and all developers to deliver new,

innovative, point of care healthcare solutions faster.– Is an adaptable platform that can incorporate inevitable changes due to

new healthcare practices, medicines, discoveries, and technologies that will be able to produce a continuous stream of innovative applications.

– Enhances existing assets and investments.
