STEM 0.2.1 Now Available

Version 0.2.1 of STEM is now available! To get the latest version, please see the OHF Downloads page. Builds are available for Windows, Linux, and Mac OS X.

New for version 0.2.1 are over 100 bug fixes, additional features and additional built-in Scenarios. The new features include new "Time Series" and "Phase Space" views. The first view plots graphs of the values of disease variables over time. The second view plots disease model variable values with respect to each other. Both views support multiple simultaneous plots of the values from different user selected regions. Additional improvements include support to displaying multiple simultaneous geographic views of more than one running simulation.

Few questions if we may...

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 ...

Scaling the community

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! We gave our emails to everyone and had an open Skype channel to give real time support.

This year we expect the community to significantly grow and the ones how used us last year to take more advantage of the OHF features and accomplish to do more tests (though it will be hard to break Donnie's record ;-).

The problem is that this year we won't have as much capacity to do real time support. We are working on better documentation, adding the IHE.b profiles to the functionality set, we will redesign our transport layer to give better security and performance, enhance the configuration model, and much more...

Therefore we plead for the community's help to help the newcomers. Explain them how the connectathon process looks like, and help solve problems. Some of the problems and questions (like OS, and .NET support) are being answered now in the newsgroup.
Please go ahead and use this tool. Your questions will be answered much faster, and maybe you'll see that someone else had already asked them before. There are tons of other benefits from using a public communication form, but I think you got the point.

Please help us scale the community,

Users feedback

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 the same time we got in the mailing list a presentation created by Corey Spears of Practice Partner, McKesson. Corey presented it on the last EHRVA conference and included lots of OHF promotion in it.

Thanks guys!

STEM officially contributed to OHF, download now available

Today IBM officially announced the contribution of the source code and resources for the Spatiotemporal Epidemiological Modeler (STEM) to the Eclipse OHF Project. In conjunction with this announcement, OHF is also pleased to announce that STEM version 0.2.0 Milestone 1 is available for download. Packaged versions of STEM are available for Windows and Linux. For help using STEM, please see the Getting Started guide and the Eclipse OHF Newsgroup.

About STEM from the press release:
The technology is designed to enable the rapid creation of epidemiological models for how an infectious disease, such as avian influenza or dengue fever, is likely to geographically spread over time. STEM, which runs on any operating system, creates a graphical representation of the spread of a disease based on a variety of parameters such as population, geographic and macro-economic data, roadmaps, airport locations, travel patterns and bird migratory routes around the world...

"A basic epidemiological model framework will be provided to software developers, who can customize and configure the models based on their specific requirements. These models, which involve multiple populations and interactions between diseases, can help public health experts develop more effective preparedness plans. IBM’s donation is also intended to help facilitate collaboration between governments, scientific researchers and other players in the public health community. Users will have the ability to share the customized epidemiological models that they create in addition to the plug-ins they build using Eclipse."

The source code and associated resources for STEM are available in the Eclipse OHF CVS repository.

OHF On The Road: European Connectathon

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. Three companies used OHF to pass EU Connectathon. They are:

… bringing the total number of vendors using OHF at the 2007 Connectathons to 12.

The great thing about actually attending the events is the invaluable feedback we receive. Our friends at Health@Net and Synapsis helped uncover and fix a few bugs in OHF code, issues that likely wouldn’t have been discovered otherwise. Many thanks to them for their help!

Congratulations to all OHF users and thanks for a great 2007 Connectathon cycle!

In that spirit, I’m also pleased to announce that a new milestone of the IHE components of OHF is now available. This milestone contains all of the bug fixes from European Connectathon as well as a few enhancements. Go here to get the binaries!

Now, we look to the future. Right now, IHE committees are preparing the 2007-2008 profiles. OHF developers are evaluating (and influencing!) the changes to current and upcoming profiles and making plans for next year. Stay tuned in the next couple months to hear about OHF’s IHE plans for 2008. In the meantime, count on an OHF contingent being present in Chicago and London next year!
