Example OperationDefinition/Resource-meta (Narrative)

FHIR Infrastructure Work GroupMaturity Level: N/AStandards Status: InformativeCompartments: No defined compartments

This is the narrative for the resource. See also the XML, JSON or Turtle format.

Note that this is the formal definition for the meta operation as an OperationDefinition on Resource. See the Operation documentation

URL: [base]/$meta

URL: [base]/Resource/$meta

URL: [base]/Resource/[id]/$meta



The meta returned by the operation

At the system and type levels, the $meta operation is used to get a summary of all the labels that are in use across the system. The principal use for this operation is to support search e.g. what tags can be searched for. At these levels, the meta will not contain versionId, lastUpdated etc. Systems are not obligated to implement the operation at this level (and should return a 4xx error if they don't). At the resource and historical entry level, the $meta operation returns the same meta as would be returned by accessing the resource directly. This can be used to allow a system to get access to the meta-information for the resource without accessing the resource itself, e.g. for security reasons



Usage note: every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification.
