The Graph Definition resource provides a formal computable definition of a graph of resources – that is, a coherent set of resources that form a graph by following references. The Graph Definition resource defines a set and makes rules about the set.

The Graph Definition resource can be used to:
– Summarize a set of profiles on resources
– Define a graph of resources to return in a query
– Define a graph of resources to include in a document
– Document rules about the relationship between a set of resources e.g. must all resources concern the same patient?
There is a close relationship between Profiles and Graph Definitions:
– A Structure Definition defines a profile, and profiles can make rules about the relationships between resources. A carefully defined set of profiles implies part of what is in a Graph Definition
– A GraphDefinition defines rules about the relationships between resources, and in so doing, implies some constraints that would need to be represented in their profiles
Profiles and Graph Definitions can be used together, or separately. When used together, they should be consistent. Note, though, that a graph definition may contain a subset, or a superset of the relationships explicitly described in the profiles it refers to.
It is possible that in some circumstances, a graph definition makes incompatible rules with the Profiles it refers to – in this case, no graph if resources will meet the constraints expressed. Applications should – but are not required – detect when such incompatibilities arise.

|Name of the concept in the FHIR structure.
|required : 1
|A Computer-ready name (e.g. a token) that identifies the structure - suitable for code generation. Note that this name (and other names relevant for code generation, including element & slice names, codes etc) may collide with reserved words in the relevant target language, and code generators will need to handle this.
|The type the structure describes.
|The "$ref" string value contains a Uniform Resource Identifier (URI) which identifies the location of the JSON value being referenced.
|A free text natural language description of the structure and its use.
|The value of the keyword should be an object or an array of objects. If the keyword value is an object, then for the data array to be valid each item of the array should be valid according to the schema in this value.
|The enum is used to restrict a value to a fixed set of values. It must be an array with at least one element, where each element is unique.
|The value of the keyword should be an array of unique strings. The data object to be valid should contain all properties with names equal to the elements in the keyword value.
|The value of this keyword can be anything. The data is valid if it is deeply equal to the value of the keyword.
|Computer Ready Name
|This is a GraphDefinition resource
|The logical id of the resource
|The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
|A reference to a set of rules that were followed when the resource was constructed
|Extensions for implicitRules
|The base language in which the resource is written.
|Extensions for language
|A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data
|These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently
|May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and managable
