Extension¶
| Short | Origin of the file behind this rendition (delivered renditions only) |
|---|---|
| Definition | Origin metadata for the file behind one DocumentReference.content entry: the channel or system
the file was delivered through.
On the content entry, not on the resource. A DocumentReference may hold several renditions of
one document and only one of them is the file that arrived; the others are produced locally. The
extension rides the delivered rendition, so derived renditions carry nothing.
source is an opaque token, naming the delivery channel as the receiving pipeline knows it.
HRM -- Ontario Health's Health Report Manager -- is the channel this shape was drawn from and the
value carried in this guide's example. No value set is bound: the set of channels is a deployment
fact, and a binding published here would make a deployment nonconformant the day it adds a feed.
Match the values your deployment produces and pass through the rest.
⚠ FIRST PASS -- do not treat this as a contract. The extension is published under a canonical
minted for it, so nothing predates it: there is no earlier address for this shape and no legacy
instance to reconcile against. A store holds instances of it from the point a delivery pipeline
starts stamping them, and no sooner. Write only source, on the content entry holding the
delivered file. |

Extension.id¶
| Short | Unique id for inter-element referencing |
|---|---|
| Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
| Cardinality | 0..1 |
| Type | http://hl7.org/fhirpath/System.String |
Extension.extension¶
| Short | Additional content defined by implementations |
|---|---|
| Definition | May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. |
| Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |

Extension.extension:source¶
| Short | The channel or system the file was delivered through |
|---|---|
| Definition | An opaque token naming the delivery channel or system that produced this file, as the receiving pipeline knows it -- for example HRM, Ontario Health's Health Report Manager. Not bound to a value set: the set of channels a deployment receives from is a deployment fact. It names HOW the file arrived, which is not recoverable from custodian (who holds the document) or author (who wrote it). |
