Proposal: Add a value for the URL field in the application
This recommendation is supported by the following considerations:
1. FHIR Standard Compliance
FHIR(Fast Health Interoperability Resources) standard, one of primary HL7 Health Information exchange standards, accepts URIs for multiple purposes.
One key use case is the identifier.system field, which is used to represent namespaces or assigning authorities.
The standard defines three specific URI subtypes for this purpose:
a. OID represented as a URI (e.g. urn:oid:2.16.840.1.113883.6.1)
b. UUID (aka GUID) represented as a URI(e.g. urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6)
c. URL ( Uniform Resource Locator)(e.g.
example.org/my-device)
2. FHIR Standard Preference for URLs:
Among these options, URLs are generally preferred within FHIR standard.
By adding support for an URL, the application can directly support data models that require this format while aligning with FHIR best practice.
3. Alternative OID Representation
Although OIDs can be represented as URIs by prefixing them with urn:oid:, this approach is often secondary and typically used when mapping data from other data models, such as HL7 V2 to FHIR.
Providing a direct URL option not only complies with FHIR best practices but also improves interoperability and facilitates cross-mapping between different health information data models.
