Many thanks for this -- are there examples of TDS schemas or instances available?
Also are there any example document instances available -- particularly for the draft Extract schema, but any instances or instance fragments would be useful.
All the best

Hi Charlie
We have an openEHR repository here with about 20 million compositions in it - how many do you want? 
regards Hugh
Hugh,
Can you expand on 20 million of what. I think htis is an astounding
figure. What is the quality of the compositions? I'd like to have more
info if possible. I think that number ois much more than any of us
anticipated.
Thanks
Ed Hammond

Many thanks for quick response
I am only after a few – more than 2, less than 9, containing a range of types of clinical information, and suitably anonymised for quoting in documents etc.
All the best

Hi Ed
We have a pure openEHR repository that has been used for load testing over the last 18 months or so. Currently it has over 350,000 EHRs (i.e. one persons record) in it and each EHR has about 60 compositions (a composition being one document such as a discharge or a test result). I have to admit that there is some variation in the archetypes and templates used but there is some sameness to the data. So we have a lot of test results, discharge summaries etc. Some are large and some are small.
Its viewable over a web application that we call EHRView - not a clinical app, but really just an EHR viewer although you can now capture data through forms built from openEHR templates. We are getting excellent performance in terms of query of this number of EHRs.
Happy to take this offline and give you more details if you would like.
regards Hugh

Thanks Hugh for the quick reply. I think this is an excellent example of
what can be achieved. Are the records real or make-up? If Make-up, how
were they generated. I would like to know, if possible, hoe to access and
look at these EHRs.
Thanks
Ed
