Description |
| root |
Uid
|
0..1 |
As specified by ISO 21090, a unique identifier that guarantees the global uniqueness of the instance identifier.
This root may be either a DCE UUID (represented in upper case), an Object Identifier (OID), or a special identifier taken
from lists that may be published by ISO or HL7. The root attribute ensures global computational uniqueness and may indicate
the identification scheme to which the extension attribute (if present) must conform (e.g. NHS Number, UK Driver Number, etc).
However, receivers must not attempt to infer the identity of the organisational entity (or entities) that manages the issuing
of an identifier conforming to the scheme (e.g. NHS in England and Wales, UK Driver and Vehicle Licensing Agency, etc). Nor
should they be used to infer the type of thing identified (e.g. patient, driver, etc). This is because a number of different
organisations may manage the the assigment of identifiers belonging to a given scheme and that such authority may transfer
from organisation to organisation over time while the scheme remains the same. Within the LRA, role types are specified using
a separate type attribute.

| extension |
BusinessId
|
0..1 |
A character string as a unique identifier within the scope of the identifier root as specified by ISO 21090 and constrained
within the LRA to type BusinessId.
The root scheme and the scheme specific extension together create a globally unique identifier for the item that this II value
identifies.

String
|
0..1 |
As specified by ISO 21090, a human-readable name for the scheme represented by the root.
|
| displayable |
Boolean
|
0..1 |
As specified by ISO 21090, true if the identifier is intended for human display and data entry otherwise false, e.g. used
only for machine interoperation.

IdentifierScope
|
0..1 |
As specified by ISO 21090, the scope in which the identifier applies to the object with which it is associated.

IdentifierReliability
|
0..1 |
As specified by ISO 21090, the reliability with which this identifier is known. This attribute may be used to assist with
identifier matching algorithms.
