Name | HL7 v2 Mapping | RIM Mapping | ServD
--- | --- | --- | ---
Identifier | CX / EI (occasionally more often EI maps to a resource id or a URL) | II - The Identifier class is a little looser than the v3 type II because it allows URIs as well as registered OIDs or GUIDs. Also maps to Role[classCode=IDENT] | Identifier
id |  | n/a |
extension |  | n/a |
use | N/A | Role.code or implied by context |
type | CX.5 | Role.code or implied by context |
system | CX.4 / EI-2-4 | II.root or Role.id.root | ./IdentifierType
value | CX.1 / EI.1 | II.extension or II.root if system indicates OID or GUID (Or Role.id.extension or root) | ./Value
period | CX.7 + CX.8 | Role.effectiveTime or implied by context | ./StartDate and ./EndDate
assigner | CX.4 / (CX.4 CX.9 CX.10) | II.assigningAuthorityName but note that this is an improper use by the definition of the field. Also Role.scoper | ./IdentifierIssuingAuthority
