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.

• 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
