Scope of coverage

To allow a client to create a push based subscription on a server so that they get notified of any resources that meet a particular criteria

this is a technical infrastructure resource not directly related to healthcare

  • subject: N/A
  • disciplines: N/A
  • delivery: N/A
  • Locale: N/A

RIM scope

Not in scope of the RIM

Resource appropriateness

  • The API provides a pull based subscription service through the history operations.
  • this works well, but is network intensive. It's fine for server:server interactions, but not suitable for client/server, especially if the client is a mobile one
  • clients need to be able create, track and retire subscriptions
  • There are 13 elements in the candidate resource. a few additional ones are under discussion

Other possible related resources

  • Message Header - is used for exchanging resources using the messaging paradigm. If we define a protocol for push subscriptions using the messaging paradigm, it would use message header
  • Query - the query resource specifies a query. This resource may or may not use the query resource for the actual query that expresses the subscription criteira

Expected implementations

  • most servers will need to implement this to support client based subscriptions

Content sources

[Josh's original proposal]: considered prior art


Example Scenarios

  • a client asks to be notified any time a new bilirubin result greater than some defined threshold is reported
  • a client asks to be notified any time new information on a patient is provided

Resource Relationships

  • there are no anticipated relationships

Timelines

  • a draft has been defined
  • implementation testing is ongoing
  • this will be ready for QA/DSTU2
