Detailed Descriptions for the elements in the SubscriptionTopic resource.
SubscriptionTopic | |
Element Id | SubscriptionTopic |
Definition | Describes a stream of resource state changes identified by trigger criteria and annotated with labels useful to filter projections from this topic. |
Cardinality | 0..* |
Type | DomainResource |
SubscriptionTopic.url | |
Element Id | SubscriptionTopic.url |
Definition | An absolute URL that is used to identify this SubscriptionTopic when it is referenced in a specification, model, design or an instance. This SHALL be a URL, SHOULD be globally unique, and SHOULD be an address at which this Topic is (or will be) published. The URL SHOULD include the major version of the Topic. For more information see Technical and Business Versions. |
Cardinality | 0..1 |
Type | uri |
Requirements | Allows the SubscriptionTopic to be referenced by a single globally unique identifier. |
Summary | true |
Comments | Can be a urn:uuid: or a urn:oid:, but real http: addresses are preferred. This is the URI that will be used when making canonical references to this resource. |
SubscriptionTopic.identifier | |
Element Id | SubscriptionTopic.identifier |
Definition | Business identifiers assigned to this SubscriptionTopic by the performer and/or other systems. These identifiers remain constant as the resource is updated and propagates from server to server. |
Note | This is a business identifier, not a resource identifier (see discussion) |
Cardinality | 0..* |
Type | Identifier |
Requirements | Allows identification of the SubscriptionTopic as it is known by various participating systems and in a way that remains consistent across servers. |
Summary | true |
Comments | Note: This is a business identifier, not a resource identifier (see discussion). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number. |
SubscriptionTopic.version | |
Element Id | SubscriptionTopic.version |
Definition | The identifier that is used to identify this version of the SubscriptionTopic when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the Topic author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions are orderable. |
Note | This is a business versionId, not a resource version id (see discussion) |
