Mappings for the astacus-observation-lab resource profile.
| AstacusLaboratoryResultObservationProfile |
| Observation | OBX |
| identifier | CX / EI (occasionally, more often EI maps to a resource id or a URL), OBX.21 For OBX segments from systems without OBX-21 support a combination of ORC/OBR and OBX must be negotiated between trading partners to uniquely identify the OBX segment. Depending on how V2 has been implemented each of these may be an option: 1) OBR-3 + OBX-3 + OBX-4 or 2) OBR-3 + OBR-4 + OBX-3 + OBX-4 or 2) some other way to uniquely ID the OBR/ORC + OBX-3 + OBX-4. |
