Topic: Search function

Alexander Zautke (Jun 22 2020 at 13:37):

I'm running in some projects into the limitation that I would like to extend an already existing resource by adding content to it through some mappings. Based on the workflow of the mapping, I know that certain resources exist in the mapping environment (e.g. a Patient resource on the FHIR server where the StructureMap is executed). These resources might have been created based on different mapping sources / StructureMaps.

Based on @Grahame Grieve proposal here on the "Mapping Support API": https://github.com/FHIR/interversion/blob/master/engine/readme.md#search, my idea would be to add some kind of "search" function:

group MapExistingResource(source src : MySource, target tgt : MyTarget)
{
    let patientCollection = search('Patient', '?identifier=test');

    patientCollection first as patient then
    {
        // tgt should contain
        src -> patient.<element> = ...;
    }
}

Any thoughts?

hmm. so I see that we have even less documentation about this than I thought

Alexander Zautke (Jun 23 2020 at 21:11):

Yeah, and I’m also not really happy of having to use a let statement at that point, but the options in the current syntax are somewhat limited I guess

Alexander Zautke (Jun 24 2020 at 22:43):

Just realized while trying to implement a prototype that the 'let' statement wouldn't be valid, see https://jira.hl7.org/browse/FHIR-21642
How would you otherwise get the result collection of the search on the source side of a statement?

I like the idea :thumbs_up:
