PCD OID Management

Overview

Object Identifiers (OIDs) fill a need that comes up in many computing contexts, for identifiers that are guaranteed to be unique. With reliably unique identifier, you can be confident that your code for a measurement or a code set won’t collide with someone else’s. Unlike GUIDs or UUIDs, which are generated by a completely uncentralized process (using an algorithm that can run on any computer that is extremely unlikely to ever generate the same ID twice), OIDs are generated by a hierarchical network of aentities each of which is the ultimate authority for its own part of the tree.

IHE PCD now is one such authority.

There are a number of ISO Object Identifiers (OID) that are used in the PCD Technical Framework. This includes OIDs that relate directly to IHE PCD developed content (e.g., the registraton of a PCD-01 HL7 message profile, which requires an OID), as well as content from outside of IHE (e.g., OIDs identifying parameters defined in the ISO/IEEE 11073 standards).

IHE PCD OID

The following OID has been assigned to IHE PCD:

1.3.6.1.4.1.19376.1.6

OID Management

The generation and management of OIDs within the PCD will be coordinated with a general method for managing OIDs within the IHE, which is being worked on now. For the present, contact a Technical Committee Co-chair for assistance if you have a need or a question in this area.

ISO/IEEE 11073 OIDs

ISO/IEEE 11073 nomenclature terms have OIDs from the arc 1.2.840.10004.1.1.1.0.0.1

See PCD SDO IEEE Coordination for a discussion of issues in the sonsistency of the ISO/IEEE 11073 OID usages.

HL7 OID Use

OIDs are used extensively as unique identifiers for codesets and similar artifacts, particularly in HL7 V3, both OIDs generated by the HL7 organization, as well as referencing OIDs from other organizations.

HL7 allocates OIDs from the arc 2.16.840.1.113883 (joint-iso-itu-t.country.us.organization.hl7).

They maintain a registry at http://www.hl7.org/oid/index.cfm.
