Implementation Guidance > Conformance Rules

[The below mentioned conformance rules are quite generic in nature and it's recommended to read through them and make appropriate changes as per the rules of IG in question.]

Conformance Rules

FHIR is a general purpose specification and imposes no particular requirements on implementers to support specific resources, operations, search parameters or other capabilities. To achieve interoperability in a particular domain, it's important that implementors make similar decisions about what FHIR capabilities those systems will support. FHIR uses the CapabilityStatement resource to define the actual or expected capabilities of a particular system.

MustSupport Flag

To maximize interoperability, this implementation guide uses the MustSupport flag to identify elements that implementers must understand in order to properly submit, process, or view. Please refer to the guidance below:

URI/UUID

Uniform Resource Identifiers (URIs) leveraged in the Ontario Patient Summary are case sensitive. URIs can be absolute or relative, and may have an optional fragment identifier. Universally Unique IDs (UUIDs) are defined in lower case format (e.g. “urn:uuid:53fefa32-fcbb-4ff8-8a92-55ee120877b7”).
