A formal computable definition of an operation (on the RESTful interface) or a named query (using the search interaction).
The OperationDefinition resource provides a formal computable definition of an operation or a named query. The OperationDefinition serves two principal purposes:
See below for further information about these, and about how operations and named queries are executed.
OperationDefinitions are published to define operations that servers can implement in a common fashion. The FHIR specification itself describes some (see below), and other organizations (including IHE, national programs, jurisdictions and vendors) are able to publish additional OperationDefinitions.
OperationDefinition resources are referred to from two different places:
This resource is referenced by CapabilityStatement and ServiceDefinition

Operations are executed by POSTing to a URL that is defined by the operation definition. Named queries are executed by performing a search with the value of the search parameter "_query" set to the name provided in the definition.
If the named query is to be performed over the RESTful API, all the parameters must be simple search parameters, so that they can be represented directly in the URL without tricky encoding issues. Named queries always return a bundle containing a set of resources, so all the out parameters must be resources, not data types.
There are two ways to pass resources to an operation: directly or by reference. The definition of an operation distinguishes between these two, since they have very different behaviors and consequences.
As an example, take the Questionnaire.$populate operation. This operation takes a questionnaire as a direct parameter. The type of the parameter is defined as 'Questionnaire'. In a Parameters resource, it would be represented like this:
<parameter> <name value="questionnaire"/> <resource> <Questionnaire> <!-- Questionnaire contents --> </Questionnaire> </resource> </parameter>
or, in JSON:
"parameter": [ { "name": "questionnaire", "resource": { "resourceType": "Questionnaire", // Questionnaire contents } } ]
Other parameters are passed by reference. For example, $populate
takes a
set of references to other resources that should be used to pre-populate the
questionnaire. These are passed by reference, and the type of the
parameter is Reference(Any)
- a reference to any kind of resource.
In a parameters resource, it would be represented like this:
<parameter> <name value="content"/> <valueReference> <reference value="Patient/123"> </Questionnaire> </valueReference> </parameter>
or, in JSON:
"parameter": [ { "name": "questionnaire", "valueReference" : { "reference" : "Patient/123" } } ]
Some operations can take either form; in that case, two distinct parameters must be defined, one for a resource as a direct parameter, and one for a reference.
It is possible for two different organizations to create different operation definitions with the same name or, perhaps more likely, to define equivalent operations that have the same name but incompatible approaches in their parameter lists.
It is also possible, though unlikely, that a server will be required to support both of these operations. If this is the case, the server is able to do this by giving one of them a new name and referring to it by definition in the capability statement. To illustrate this, assume that two different organizations, "orgA" and "orgB", both define an operation called "dothis", and the definitions are incompatible. OrgA publishes its operation definition at http://orga.com/fhir/dothis.xml, and OrgB publishes its operation at http://fhir.orgb.com/meta/OperationDefinition/dothis. The server is able to implement both. Its capability statement will say:
<CapabilityStatement xmlns="http://hl7.org/fhir"> <!-- snip --> <rest> <!-- snip --> <operation> <name value="dothis"/> <definition> <reference value="http://orga.com/fhir/dothis.xml"/> </definition> </operation> <operation> <name value="dothis2"/> <definition> <reference value="http://fhir.orgb.com/meta/OperationDefinition/dothis"/> </definition> </operation> <!-- snip --> </rest> <!-- snip --> </CapabilityStatement>
If a general purpose cross server client is looking for the implementation of the http://fhir.orgb.com/meta/OperationDefinition/dothis operation and wants to be robust against this name clash problem, instead of simply executing the $dothis operation, it can look at the server's CapabilityStatement for the underlying definition URI and then execute the name given in the capability statement.
A client can determine the compatibility of the server by processing its capability statement and ensuring that the server implements the specific operation definitions and parameters required by the client. The client can then report a useful error to the user rather than allowing mystifying operational errors to occur.
However, there are fundamental limitations to this approach because there are many aspects of these operations that are not (or cannot be) defined in a formal fashion using OperationDefinition, for example, co-occurrence constraints among parameters.
In the same sense, a 3rd party tool can examine a server's CapabilityStatement and a client's definition of an acceptable server to determine whether those two system are interoperable or not.
Finally, it is possible to generate user interface forms automatically from
the OperationDefinition. The documentation in the OperationDefinition.description
and OperationDefinition.parameter.documentation
should be sufficient to allow
moderately technical users to guess at the correct content of the form.
For this reason, highly technical documentation should go in OperationDefinition.comment
.
It is anticipated that this would be used to automate development processes, rather than to generate end-user forms: such users will usually need more support than can be offered in a generated form.
