In the lines of the last post, we would like to get some community feedback in order to help us better decide on our future plans. We will start to post some polls and post them in the OHF site. We'll publish a note about new polls in the OHF newsgroup, so please pay attention if you wish to influence.The first poll will be about the ultimate question:To be or not to be? That is XDS.b ...

As we are starting to rump up towards the 2008 IHE Connectathon we recognize we're going to have a better manage user community scalability issues.Last year we had a nice small user community with about fifteen ISVs going with us to the Connectathon and few more how used OHF in the NHIN prototypes and other projects.Those where fun days!

The recent announcement of the of STEM triggered tons of press and blogs articles about STEM and OHF which was great. It lead a significant increase in the web and mailing list traffic.In the IHE front, our user community is helping us a lot to push the word out. I was told by few attendees of the IHE Workshop occurred last week that Jyran Glucky of BlueWare did a lot of OHF promotion.At about

Greetings Everyone,Last month (or was it the month before :)), Sarah and I crossed the pond to support OHF users at the IHE European Connectathon in Berlin, Germany. Like any Connectathon, it was an intense week of emotions that varied from anticipation to stress to shear panic and finally, relief.This is the first year that OHF participated in Europe and we had a nice showing.

Just read in Linux Med News about WorldVistA EHR VOE/ 1.0, a CCHIT Certified Ambulatory EHR for 2006. These are really great news to the open source community, and it got me to read further more about the CCHIT Interoperability Criteria.The bad news are that it will be harder to be certified in the future because IHE interoperability will be a requirement.The good news are that no one has to do

In addition to the growing number or European committers in OHF, we have an increasing European activity.The European Connectathon is getting closer. We'll have at least two committers there supporting our users (Sarah and Matt).

Most of the OHF committers were able to make the meeting, and OHF had a number of activities, ranging from a long presentation to a committers meeting as part of the healthcare day on Thurs. In addition, some of us were able to make it down to IBM Almaden for a followup day on Friday.One of the more important parts of EclipseCon was the

OHF had achieved some amazing results at the HIMSS Interoperability Showcase, demonstrating yet again how an open source community can get things done.OHF, using the IHE components and the bridge, had enabled IHE based interoperability for eight open source and commercial applications there. We also had a support team on site (Sarah, Sondra, and Matt) to make sure everything ticks, and so it did

The Healthcare Service Bus (HSB) is on the road for some time now, thought of giving it some daylight. I thought about HSB when the OHF Bridge came through, and I know Don is rolling the idea too. The basics is so new, you take an Enterprise Service Bus (ESB) hook it up to a bunch of Healthcare IT services and there you go, an SOA dream come true :-)In a good RHIO we should see a flora of

Since the Healthcare Services Specification Project (HSSP) announcement I didn't see many posts about our relationships with hl7.org. Therefore I was happy to stumble upon David Falwell's blogOn a positive note, I did email hl7.org about the availability of the open source eclipse plug-ins that are being developed for HL7v3.

Last week I had the pleasure to talk at the Open Source Health Care Summit which was part of SCALE 2007. I did the talk together with Matt Excell from Possibility Forge who integrated the OHF Bridge into openEMR.The presentation is available at the SCALE web page.Slide 9 in the presentation is a bit mysterious.

Here is a short numbers driven post to estimate performance.IHE Connectathon at Chicago (Jan 07)isch9 vendors used OHFThe average number of tests OHF users passed was higher than the number passed by others who didn't use OHF. For example, OHF users like MedQuist, MedCommons, and Practice Partner each passed about 30 tests.Some of the vendors using OHF passed a landmark number of tests including

The Nation wide Healthcare Information Network (NHIN) prototype demos which where presented at Washington DC two weeks ago marked an important milestone to OHF. One of the perticipents of the Connectathon was using a fully standard interoperability system using the IHE XDS, ATNA, and PIX profiles. This system was marked by few independent groups as the best system in the demo.The important part

--This post was prepared by Melih Onvural - an OHF committer--The OHF project took large leaps and bounds forward during 2006. A congratulatory look back is warranted as OHF is poised to grow even larger in the year ahead.2006 started with the project trying to find its feet. The first large challenge was bringing together the full group for a FTF to help define the projects and directions for

In the next year we are going to be attacked by a massive amount of events.Only in the first quarter of next year you will see OHF at the IHE Connectathon, EclipseCon, NHIN prototype demonstration, and HIMSS.In the last event we where at (LinuxWorld Healthcare Day) we found we need an OHF shirt!

With the latest new OHF committers nominations we now have committers from the Academia , which I think is healthy for every open source project. We have now Kelvin of Columbia University, Matt of the University of Oklahoma, and Melih of North Carolina State University. Ivan of Wharton School told me he'll continue to donate efforts publicising OHF in Blogs and Journals e.g. http://tmlr.net/jump/

While the electronic registration for Connectathon open date is getting closer, we are focusing on what IHE actors and workflows will OHF support using the IHE Client plugins and Bridge (for LAMP/.NET apps).While OHF is starting to receive feedback from costumers which are going to use it in the connectathon, additional feedback is welcome.

Next week we'll discuss and demo OHF at the first ever Healthcare Day at Linux World Conference & Expo. After demonstrating this in the IHE workshop few weeks ago, it will be interesting to hear the responses from a conference that is not IHE focused.In the panels, Don Jorgenson and James Kaufman will talk about all aspects of OHF.

Among others, the Eclipse OHF project is being used in several events sponsored by Integrating the Health Enterprise (IHE) and Health Level 7 (HL7). The OHF IHE plugins build atop of other core OHF components (security, and HL7 stack for example). OHF members are active in the IHE committees, and share the goal of true interoperability in healthcare.One could argue that the IHE specifications can

A team of talented Extreme Blue students, Matt Davis, Kelvin Jiang, and Melih Onvural, had built the OHF Bridge in an effort to make the OHF tools available to existing applications. The architecture is quite simple: Eclipse plugins, communicating using SOAP through an Axis Engine, sitting inside of an OSGi instance, within Tomcat. There are many technologies involved, but the solution is simple

Given the rather open nature of HL7 V2, it's strange that conformance profiles are not more widely supported and adopted. I think that there's several reasons for this:HL7 V2 is so loose that conformance profiles don't have the same meaning as for other standardsConformance Profile specifications have lagged behind the standard itselfThere has only been a few tools available to create or use

I've been at the HL7 meeting all week. This has been an unusually busy meeting, and there's a number of things to report.The HL7 Tooling Committee has initiated a joint project with Eclipse OHF for development of HL7's own V3 pre-publication tools and some other tools which will also be useful to implementors. The project has been driven by the UK NHS, and has been approved by the HL7 board.There

Though this testimony does not come from the OHF project, it benefits the healthcare FOSS ecosystem. Open source software is less well developed in health care than for some other enterprises, but open source software solutions for health care are now rapidly evolving.In this vein, I urge the Committee to consider making open source software the first consideration in selecting any new software

Of the many open questions around OHF, there's 2 that are closely intertwined and will be a source of a great deal of contention on an ongoing basis. The first is what the scope of OHF is, and the second concerns relationships with other open source initiatives."Healthcare" is a rather open concept. It covers things such as financial arrangements for the provision of medical care, record keeping,

I'd like to thank every one who took the time to attend the meeting.I was encouraged by the attendance.

This Forrester Research report was prepared for the California HealthCare Foundation at Match 2006 (i.e. this month).Here is a summery of the report conclusions:... While not heralding the end of commercial software vendors, the report concludes that conditions are ripe for open source solutions to take root in health care, and that it will likely become the standard for capturing, sharing, and

The OHF on Server project goal is to help products utilize the standard based OHF healthcare plugins. OHF on the server will expose OHF plugins via web services to be used by any product (say LAMP,.NET, MUMPS or Java based). The code base of the plugins had already passed the IHE Connectathon 2006 tests with full success, and was used by few third party products (during the Connectathon!).
