Hi Alessandro,
Let me say this in advance; none of what is written below is there to
discourage you, or to express any negative remarks about your
intention.
I think the best thing I can do is to give you a picture of where you
are now, and others may help in other ways.
You have a thesis to complete, which is what I would see as
implementing an openEHR based information system, then performing some
analysis to infer about a particular state (in danger or not)
Based on your questions, I think you need to understand openEHR better
first, before attempting to implement an actual system. If you think
that you can just download some sort of installation package and start
using it to enter/store/read data right away, this is not as easy as
you think it would be. We'll get to this.
First, you need to read openEHR documentation, to understand what
openEHR is all about. You need to understand the roles of the
following: ADL, Archetypes, Reference Model, Templates (probably not
as important as the others for you) and the relationship between them.
If you try to move forward without having at least an intermediate
understanding of these, you'll certainly have issues and you will lose
time. The documentation of openEHR is really good, and it is available
as pdf files. It is however a dense set of documents, so don't expect
to go over them in two days and figure it all out.
After you fell you have an understanding of how this all works, you
can start hunting for existing work. There are various attempts to
deliver software that may help you out in doing what you're doing, but
you'll have to work on them to see if they are actually going to help
you. Tim Cook, Pablo, and I have provided software in open source
form, but you need to work on these options. I for one can say that my
work is still immature, and will take time to become a one shop
solution to all things you'd like to do with openEHR.
In short, try to establish a solid understanding of openEHR first,
then move the implementation matters, or you'll lose valuable time.
As you progress, you can ask your questions here, and I'm sure you'll
get help from the community.
Good luck!
