Re: [Health-dev] HL7 PDQ module

[Vittorio Meloni]

Hi all,

we just pushed the two modules. You can find them in tryton/hl7 and tryton/pdq. You can read some documentation in the docs directories of the modules. 

To make them work you need to install HL7apy from pip (pip install hl7apy==1.1.2). At the moment we thought it would be too soon to put the dependency in the gnuhealth_install.sh script.

In this first implementation we haven't used the FHIR classes to access patients' demographics but we agree that it would be more advisable to use them in next releases.

Hope you enjoy the modules :-)

Good point. The interfaces are different, from what I gather, since that
is working with HL7 v2.x. The patient searching is... meh. I mean,
I just used the search/search_read/etc. methods on the models. I suppose
they could use some of the code that creates complex tryton search
queries from arguments. Although it's rather ugly. Hehe.

Awesome! I'll take a look! HL7 v2 is more widely supported (I think), so
this is good stuff.
