OHT Platform Projects & Roadmap (Part I)

• OHT Platform– Phase I: SOA Implementation

• Implement HSB and Common Services using current middleware stacks and web services

• Wrappering existing APIs in order to publish new web services (mainly these are code and schema generators)

• Data modeling and data transformation tools• Creating and parsing XML based representation of EHR data• Managing elements of the distributed system and routing messages

between them• Simplifying SOA interactions and service composition by using programming

models (typically this translates to a combination of code generators with coding guidelines and conventions)

• Administration of the resulting distributed SOA based system (e.g. error handling, logging, etc.)

– Phase II: Scaleable Platform• Scale out to more platforms and optimize for better performance• Add richer data interchange, more data formats, better admin tools, etc.

OHT Platform Projects & Roadmap (Part II)

• OHT Platform Simulator– Instrumented development and test platform

• Legacy Adapters– Framework and tools to assist with building adapters to legacy systems

• Medical Device Integration– Based on IBM SODA framework
