Extension¶
| Short | Composition EHR Share Extension |
|---|---|
| Definition | One completed share of this signed note to an EHR outside the practice. Repeats: a note shared three
times carries three.
Completed shares only. A share still in flight is not recorded. This element is read back to
patients as a disclosure record, and listing a pending share would tell a patient their record went
somewhere it has not yet gone.
The destination is a string, not Reference(Organization). It is routinely an external system
with no Organization in this practice's directory, and a reference that cannot resolve is worse than
a name that can be read.
FIRST PASS. This extension is declared from its production shape rather than from a modelling
pass. See the file comment for the canonical it publishes under and why that is not the URL the
software writes today.
MIGRATION. Nexus EMR writes this extension today at
http://services.well.com/fhir/StructureDefinition/composition-ehr-share. That address is live in
stored notes and in code, and is under migration to the canonical declared here (FHIR-370). Write
the canonical; when reading, match on the URL suffix composition-ehr-share so that notes filed
under either address are seen. |

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. |

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.url¶
| Short | identifies the meaning of the extension |
|---|---|
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |
