HL7 maintains an OID Registry of globally unique ISO (International Organization for Standardization) identifiers. We have officially registered an OID in order to serve as an authority for OIDs within this namespace.
Official OpenMRS OIDs
| OID | Description | Example |
|---|---|---|
| 2.16.840.1.113883.3.7194 | Root OID for OpenMRS. | |
| 2.16.840.1.113883.3.7194.1 | OpenMRS Implementation Identifier. | <id root="2.16.840.1.113883.3.7194.1" extension="AMPATH" /> Where "AMPATH" is the implementation ID. |
| 2.16.840.1.113883.3.7194.2 | OpenMRS Patient identifier | <id root="2.16.840.1.113883.3.7194.2" extension="1234-4" /> Where "1234-4" is a patient identifier within an OpenMRS implementation. Note that we do not define separate OIDs for every identifier type. If needed, the identifier type could be specified within the extension. |
| 2.16.840.1.113883.3.7194.3 | OpenMRS User identifier | <id root="2.16.840.1.113883.3.7194.3" extension="1234-4" /> Where "1234-4" is a user's identifier (e.g., system ID) within an OpenMRS implementation. Note that we do not define separate OIDs for every identifier type. If needed, the identifier type could be specified within the extension. |
| 2.16.840.1.113883.3.7194.4 | OpenMRS Provider identifier | <id root="2.16.840.1.113883.3.7194.4" extension="1234-4" /> Where "1234-4" is a provider's identifier within an OpenMRS implementation. Note that we do not define separate OIDs for every identifier type. If needed, the identifier type could be specified within the extension. |
