[Gnumed-devel] schema and test results

[J Busser]

In test_type there is a field coding_system described as:

> UNIQUE#1 
> identifier of coding system that the code of this 
> measurement type is taken from
> should be
> verifiable against the "reference" service of
> GnuMed

I noticed also tables ref_source and test_norm .

Ref_source is meant to hold coding systems, so is test_type meant to have an fk constraint?

Also, if you don't mind, how is test_norm meant to be used? (I could find nothing in the gnumed-devel archive)
