Hi Divya,

Thank you for your interest in OSHIP.

Same as I sent to Xue Yu, please send these to the mailing list. :-)

BTW: Good news on this.  The Google Health Python API has just been
added to the GDATA trunk.  Opening up lots of possibilities for
application developers to use other Google services (Google
Earth/Maps?).

Great.

A key openEHR/OSHIP concept here: We are dealing with an "information
model" NOT a "data model".  That is what makes it transparent across
implementations. If you read my paper "Where the context lies" and you
did not get this understanding then let me know.  It means I need to do
version 2.  ;-)

As far as the openEHR Extract is concerned, there is a sub set of ADL
named dADL that is a purpose specific language designed to be
semantically lossless.  Yes, there are some XML possibilities but you do
or are at least likely to lose some semantics.  However, popularity of
XML means that we cannot totally ignore it (as much as some of us would
like to. ;-)

As in the above answer.   The information model is the same across all
openEHR systems.  How each implementation handles persistence is up to
them.  There is a discussion on this here:
http://www.openehr.org/wiki/display/dev/Persistence (see the child
pages)

My personal belief is that we are working with objects then we should
use an object database.  Hence my choice of the ZODB for the OSHIP core.
I realize that this isn't always an option for some applications and we
have options to an SQL database.  In fact one of the 'ideas' is to
explore those options and develop examples for application developers.

If you haven't already, please read the required reading I sent in the
letter.  There are also many many resources on the openEHR site that
describe the significance of the reference model being rather
generalized with archetypes and templates expressing constraints on that
model in order to describe one (archetype) or a group (templates) of
clinical concept(s).

Cheers,
Tim
