Background on this Contribution

The Eclipse Open Healthcare Framework is an Eclipse Technology subproject created in 2005

Four committer companies, roughly 20 Eclipse committers

IBM’s participation approved by OSSC and ERB in October/November 2005

Goal was to create an open-source framework for building interoperable, extensible healthcare systems

IBM Research’s contributions to OHF include: Integrating the Healthcare Enterprise (IHE)

High Level Description of IBM Contribution

IBM Research: Created the IHE Charter Project at Open Health Tools Transferred source code and documentation for the

following Eclipse OHF components developed by IBM Research to the IHE Charter Project at Open Health Tools:

IHE component Bridge component

Has made additional contributions of source code and documentation for these components to the IHE Charter Project at Open Health Tools

Will, at an appropriate time, discontinue additional work on and eventually archive the Eclipse OHF IHE and Bridge components

IBM Contribution DetailsThe IHE Component is an implementation of Integrating

the Healthcare Enterprise (IHE) profiles and transactions The IHE is a healthcare-focused body that profiles

interoperability transactions through open standards (such as HL7 and DICOM)

OHF provides API-level tooling to IHE interoperability transactions, such as document and patient identity sharing

Native Java, packaged as Eclipse plug-ins, 550k LOC

The OHF Bridge component is a server-side reference implementation of the IHE component, designed for use as a Web service (Tomcat/Axis)

Provides simplified, platform-neutral access to IHE component

Java+OSGi extensions, packaged as Eclipse plug-ins, the proposal use case for server-side Equinox, 20k LOC

Strong user community 15+ vendors have tested using OHF/OHT at Connectathons

What stays the same

Overall code base is mostly unchanged Both Eclipse plug-ins and Bridge remain Existing users will need minimal updates Changes required for CPs, ATNA, new profiles, and Java

packaging

License, source vetting, IP indemnification Eclipse Public License OHT Development Process almost identical to Eclipse

2009 NA Connectathon

Fourth year of on-site user support at the North American Connectathon

General plan Committers available for support and bug fixesSkype chat for user support and discussionsWeb site with Bugzilla, updated buildsBridge RHIO Configuration with Registries and

Repositories listed

Like last year, our implementation will be tested as a formal system

Expanding Committer baseExpanding Profile coverageCode Review

Look for framework components (ex. security, web services?)

Look for overlap with other projects (ex. HL7 workbench, tooling)
