Topic: datatype uuid and regex
Jens Villadsen (Mar 04 2020 at 23:51):
It does not look like there's a regex backing the uuid datatype from what I can read on http://hl7.org/fhir/datatypes.html#uuid. Is there any reason why this is indeed the case - that e.g. something like [0-9a-fA-F]{8}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{4}\-[0-9a-fA-F]{12} is not used?

probably an oversifht
Jens Villadsen (Mar 05 2020 at 08:40):
I just need to know if I need to provide a FhirPath expression to the value or not in order to verify that the format of the UUID is conformant.
Jens Villadsen (Mar 05 2020 at 08:42):
And to complicate matters even more: https://stackoverflow.com/questions/136505/searching-for-uuids-in-text-with-regex/38191078#38191078
Grahame Grieve (Mar 05 2020 at 08:48):
the validator checks that it can convert the string into UUID
Grahame Grieve (Mar 05 2020 at 08:48):
so you don't need to
Jens Villadsen (Mar 05 2020 at 08:49):
and the same goes for FhirPath datatype casts?
Grahame Grieve (Mar 05 2020 at 08:49):
umm?
Jens Villadsen (Mar 05 2020 at 08:50):
hmmm ... that last part may not be necessary ... I'm not entirely done with the design ...
Jens Villadsen (Mar 05 2020 at 08:51):
But I need to verify that the UUID is a v5
Jens Villadsen (Mar 05 2020 at 08:51):
so I'll end up with a FhirPath match regardless
