2.26.3.7 Mappings for RIM Mapping (http://hl7.org/v3) 
| Identifier | II - see see identifier pattern at http://wiki.hl7.org/index.php?title=Common_Design_Patterns#Identifier_Pattern for relevant discussion. 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] |
| use | Role.code or implied by context |
| type | Role.code or implied by context |
| system | II.root or Role.id.root |
| value | II.extension or II.root if system indicates OID or GUID (Or Role.id.extension or root) |
| period | Role.effectiveTime or implied by context |
| assigner | II.assigningAuthorityName but note that this is an improper use by the definition of the field. Also Role.scoper |
