Of course you can write any validation tool you want, but you cannot
do this and still conform to the XML Schema standard, that is why
Schematron became important. With Schematron you can validate
anything. As I wrote this morning, LinkEhr also generates Schematron
for validation purpose.
this already works (for nearly 10 years) and it validates against the
XML schema standard. What it doesn't do is validate everything you want
to validate, i.e. not all things in the archetypes. But it's good enough
most of the time.
To do things properly, I agree, you would probably use Schematron + XSD,
or personally I have always thought that Schematron + Relax-NG would be
better.
whether this is the real requirement being talked about here may be
another question.
You are right, it was not what was asked, still I thought it would be
interesting for others to know that there is a JSON Schematron parser
(instead of an XML Schematron-parser), which can be used to validate
JSON OpenEhr-datasets against archetypes/templates.
that might be an interesting thing to have in the openEHR toolkit. We
are just now revising and re-organising all the openEHR XSDs, and also
adding in some JSON-schemas. Any related artefacts that anyone wants to
contribute, or fragments that could be used in something larger would be
appreciated - it will all get posted in the specifications-ITS-XML git
repo under the usual CC licence.
