You don't need to constrain the TERM_MAPPINGS to use it.

I was checking again with the multiple simultaneous terminology mapping on one

TERM_MAPPINGS could do, but the archetype-editor, nor the ocean, nor the 
linkehr support it. The template-editor does not support it well. This makes it 
unmaintainable for the company I work. I could hack it in the datasets, but I 
am only on temporary base here, that is why this

It seems that other have similar problems, and I think a revise of the RM is 
necessary. Multiple defining_codes on one DV_CODED_TEXT does not break existing 
datasets or archetypes.

And to support the non-code-hackers, a new check on the tooling  (regarding to 
term-mapping) will be necessary, even to support the existing RM features.

See SPECPR-132 and proposed solution in SPECPR-165 which is designed to not 
break the current schema. They appear to be assigned to R1.1 but not progressed 
to a CR.

Perhaps I have come in at the wrong point of the conversation and missed the 
original question but I believe that the SEC has already approved a change (or 
at least got a change proposal from me, I’ll need to follow up to find the Jira 
card) to add a value to the mappings code phrase. Is this a solution to your 
issue?

Subject: Re: Problem with constraint_binding



We are considering that Diego, the fact is that the customer wishes to code the 
name -item two times. Both coding - systems are not easy to map and the mapping 
cannot be calculated easily by software.



So we need two Dv_coded_text's to carry the codes, and only one value to carry 
the name.



The problem with to Dv_coded_text's is however that it offers two value - 
fields and that is not what we want.



It is a pity that a Dv_coded_text only can carry one code. I don't understand 
that restriction but we cannot solve that now, I hope this can be considered in 
a RM change.



So I think, we will have two Dv_coded_text's and from one having the value put 
of in a template if that is possible. I look into that tomorrow.



Best regards

What about having two sibling DV_CODED_TEXT nodes as alternatives on the 
parent? (or specialize two different ones from the single parent one). That 
would allow to arbitrarily define constraint binding as needed, and in data 
only one would be correct one

Hi Bert

This is correct. If you were to add those constraints in a specialised 
archetype, at run-time the submitted term in the defining_code attribute would 
have to come from one of the two terminologies specified.

The constraint can define multiple potential terminologies but only one 
defining_code is allowed in the instance data.

Dear readers,



I have a problem and I want to ask your advise.



The problem is that I want to use openEHR-EHR-EVALUATION.problem_diagnosis.v1 
which is in CKM.



In that archetype is the item "Problem/Diagnosis name", which is of type 
DV_TEXT. We want to use it as DV_CODED_TEXT, because we want to add code to the 
entered name.



In this situation where I work, the customer wants to use 2 different codes, 
one company crerated internal codelist, and ICD10.



It seems easy to arrange in the archetype, I think I need to specialize it, 
because I want to add the constraint-bindings to give room for the codes. The 
archetype-editor from Ocean allows two constraint-bindings on the same node, 
like displayed below. But this seems wrong to me.



In the reference model in the DV_CODED_TEXT is one CODE_PHRASE (1..1). And 
CODE_PHRASE  has terminology_id and code_string also 1..1



So how will the construct below be interpreted following the specs?



constraint_bindings = <

["ETDA"] = <

items = <

["ac0001"] = <terminology:ETDA>

>

>

["ICD10"] = <

items = <

["ac0001"] = <terminology:ICD10>

>

>

>



My second question, if you say this is impossible to add two terminology 
constraints to one data-item, which construct do you advise to make two 
terminology constraints_bindings available to one DV_CODED_TEXT (or maybe 
another datavalue-type)?



Thanks for any help.



Best regards

Bert Verhees
