there a wiki page for the Emergency Response Demo, particularily a page or
number of pages that gives the kind of detail that one would expect eventually
would be developed?
particular, there may be a detailed scenario description and the list of all
services, with standard formate for convaying specificdata objects between
may be a published standard for core data objects, a registry and repository of
service definitions, as well as demonstration of service discovery and the
orchestration of service responses.
to admit that I have not followed the demo development for months. The
demo discussions and processes started (May, 2006?)
was interested in was how service discovery would be
developed. If, in an emergency, required services are not
available from a standard set of data objects and interfaces, how would a
required service (one that was not in the standard core but absolutely necessary
in the emergery response) be identified/measured.
OASIS BCM (business centric methdology) and SOA Blueprints specifications have a
process model for the aggregation of new service defintion in real time.
Was this process model used in the Emergency Response demo, and if not how are
the issue of novelty addressed?
approach the modeling of event space using the notion of natural category.
As recently suggested, there are two types of natural category, natural category
that is stable and natural category that emerges as part of natural
Services may be defined as transactions in a natural category space,
where the transactions have charaterisitic event chains.
Web-services and "natural services" then are reflections of each other;
sometimes these reflections have high fidality and sometimes they do not.
any of the demos specifically address the issue of fidality, or of outcome
metrics on the usefulness of a service specification?
I have started writing into the
SOA demo spec located here: http://colab.cim3.net/cgi-bin/wiki.pl?SoaLobDemoSpec
Please take a look at it and
consider contributing along the lines we have discussed. We should be
able to develop a good deal of the specification on the Wiki – all you need do
is register for the wiki and make updates. If there are open questions
or controversial parts please discuss it on the mail list prior to changing
We also need to start work on the
technical considerations – registry and web service details. Lets try
and get “hello world” running very soon.
