OID (Object Identifier) are identifiers for objects standardized
worldwide by ISO/ IEC 9834/1. This identification for objects and
concepts ensures standardized information exchange.
Central registers (with no commercial interest) secure the
uniqueness of the OID for each concept and thereby avoid
DIMDI and HL7 Germany developed a database with a standardised
XML structure for data exchange of Object Identifier (OID) in the
healthcare system and DIMDI is handling the registration since
OID - Good practice
The assignment of new OID is effected by following the rules of „Good
practice for the assignment and usage of OID“.
• The structure of the OID does not represent a hierarchy or classification. It
is solely used as a reference to a description.
•Once an OID is assigned it will never be taken back and stays a valid
identifier for this concept.
• The assigning authority, being responsible for the uniqueness of the
OID, checks the content of the OID-application. (Quality check)
•If an organisation becomes registration authority within the tree of OID they
can assign OID self dependently by preserving the uniqueness.
• An authority should not assign an OID for concepts or objects being used
not solely within its organisation. These OID should be assigned by the
central registry (…for each country).
•International OID should be assigned by a central international OID-
