Re: [technology-pmc] Proposal for STEM to be a project under the Technology PMC (was OHF project shutting down)
|
SAT is supposed to move to Equionx.
I believe SODA should move to RT
AFAIK, OHF as a project is being shutdown and all the relevant pieces
need to find a home...

hi Dan
I believe that it is not true to say that the OHF project is "shutting
down", though it's future is certainly up in the air.
We have the following components in OHF
* IHE/Bridge
* HL7 v2
* HL7 v3
* WADO
* STEM
* SODA/DK
* CTS
Of these:
* IHE/Bridge has moved to OHT
* HL7 v2 and v3 will move to OHT
* I have not heard any discussion about WADO
* SODA was talking about moving DK to Equinox, but I've not
heard what happened there. SODA was going to stay in OHF
last I heard?
* CTS hasn't really happened and I'm not sure what the plans are.
Leaving you guys.
I'm not against this proposal, but would like some discussion about
the future of other OHF things as part of this discussion

Following up on Wayne's note regarding the OHF project shutting
down. The STEM project http://www.eclipse.org/ohf/components/stem/
(an OHF component) would like to propose its inclusion as a separate
project under the Technology PMC.
STEM is an acronym for "Spatiotemporal Epidemiological Modeling"
system. It is a Eclipse based RCP designed to be a globally
accessible platform for disease modeling. The short summary is that
it combines mathematical disease models with extensive (i.e.
"complete") global geographic and population data sets and geographic
visualization. It leverages Eclipse's plugin architecture to allow
other researchers to contribute their own mathematics, data and other
extensions. It should be noted that while the initial target for
STEM is disease modeling, it is general enough, and is implemented to
facilitate, other types of modeling scenarios, some of these could be
disaster planning and response, real-time situational awareness,
military modeling, public policy decision support and layered
economic models.
One of the main innovations in STEM is use of a "composable" graph as
the representational framework for its simulations. This means that
a researcher can create a model by combining various components of
the graph from different sources. STEM includes "built-in" graph
components representing all of Earth's 244 "countries," as defined by
the ISO-3166 level 0 standard. The components include political
subdivisions, geographic relationships, population data,
transportation infrastructure and other aspects of the political and
physical geographic of the Earth. These "building blocks" can be
incorporated into any model and their general availability avoids the
need for disease model researchers to "reinvent the wheel" by having
them find and manage their own data sets. In addition, a researcher's
own models can be exported from STEM and imported by others to
facilitate collaboration. STEM includes extensive geographic
visualizations of disease spread.
STEM currently has four Eclipse committers who are funded by both IBM
Research and the United States Air Force. The committers work in the
United States and Israel. In the future, additional developers may
join the project from IBM Research's labs in Asia. The project has
extensive connections with academia including the University of
Vermont, MIT, Tel Aviv University and Johns Hopkins Bloomberg School
of Public Health. The project is also ramping up its publishing
efforts with a recent acceptance of a paper at BioSecure 2008 (joint
with University of Vermont) and a submission of a paper on its
transportation model to PLoS One. A book about the project is in the
proposal stage. STEM was presented at the CODIGEOSIM Disease
Modeling workshop at York University in Toronto last month, and will
be presented at the INFORMS conference
http://meetings.informs.org/DC08/ in Washington DC on Monday, and at
the IBM Global Pandemic Initiative (GPI) workshop in Washington DC,
later in October. We'll be proposing a talk on STEM at the next
EclipseCon.
The STEM code base makes extensive use of EMF, with all of its core
components being modeled and then generated by EMF. It also
leverages BIRT for many of its visual components. There is an
extensive set of JUnit test cases and the implementation has
integrated run-time self testing in the form of a project specific
DBC "class invariant" implementation. The project's IP Health is
good, all of the data sets have passed through the Eclipse IP process
and all of the code has been written by Eclipse committers. STEM's
feature set has stabilized in recent months. The project's builds
are stable. The documentation is good and improving (the project has
hired a dedicated technical writer to help with this area). The
current version is 0.3.0a. No project is perfect, or ever done,
there are still many things to improve. To that end, we're working
on improving our release engineering, our usability and we are
developing more advanced mathematical models and techniques for
inclusion in the code base.
The project has been well sheltered under the OHF umbrella as it has
matured, but given that that project is now "shutting down", the
project members are very happy with Eclipse and think it would be a
good time to move directly under the Technology PMC. We would use
such a shift as an opportunity to revamp the project website and
supporting documentation as well as refactor the code base to reflect
our experience and hindsight. It would also be a good point for the
project to expand it's efforts to attract more developers; having a
more visible, independent, presence under the Technology PMC should
help with that.
Many thanks for our consideration of this proposal.
