Missing search parameter for ITI-67

[Ivan1pl]

There is a new version of ITI-67 transaction specification and it defines an additional search parameter (full list) that is not supported in current version of Iti67SearchParameters.

The missing parameter is: creation: This IHE defined parameter defined as DocumentReference-Creation, of type dateTime, specifies a search against the DocumentReference.content.attachment.creation.

This is basically about lifting the MHD specification from 3.2 to 4.0.1. There is a variety of incompatible changes listed here and we yet need to find a way to include them consistently without breaking too much for existing FHIR R4 MHD implementations. Proposals welcome.

[Ivan1pl]

If the versions are not compatible, then maybe (as temporary solution) have separate implementations for both versions? And make specification version part of route configuration. For example:

from("mhd-iti67://serviceName?spec=old")

from("mhd-iti67://serviceName?spec=new")

With new as default. For existing implementations using 3.2 specification, the only required change would be to add ?spec=old to route configuration.

If that's not possible, we could also implement mhd4-iti67 (and others).

MHD 4.2 support is added in IPF 3.8.0
