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.

OID Allocations

No OIDs have yet been allocated under the PCD arc.

ISO/IEEE 11073 OIDs

<Note: Provide X73 OID arc examples and usage>

HL7 OID Use

<Note: Discuss how PCD uses OIDs w.r.t. HL7-based artifacts>
