Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction
OID (Object Identifiers) are unique identifiers for any kind of objects. A globally unique identifier for
each of these concepts will help to ensure international exchangeability of objects within different
applications (e.g. healthcare information systems).
In the exchange of healthcare information, additional information about the object being identified is
generally very beneficial but typically not contained in a transaction of data between systems. Such
information (responsible organizations, a human readable name, a description of the object, etc.) is
referred to as the OID metadata and is housed in an OID Registry.
Today, due to lack of standardization of the set of metadata (both content and structure), existing OID
registries are not compatible.

TECHNICAL SPECIFICATION ISO/TS 13582:2015(E)
Health informatics — Sharing of OID registry information
1 Scope
This Technical Specification specifies the mandatory and optional information to be recorded in any
registry of OIDs, using an information model.
It specifies which parts of that information are to be regarded as public and which parts are to be
subject to security and privacy requirements.
All registries support the recording of mandatory information, but the recording of any specific
object identifier in one or more repositories is always optional. In some cases, security and privacy
requirements are more stringent for e-health applications.
In detail, this Technical Specification:
— specifies an information model and a corresponding XML format for the export of the contents of an
OID registry, suitable e.g. for import to a different OID registry;
— references common Use Cases for OID registries/repositories;
— references an Object Identifier Resolution System (ORS) which provides a look-up mechanism for
information related to an object identifier, with guidance on the use of that facility.

4 Explanation of terms
4.1 OID registry and OID repository
An OID registry maintains a list of OIDs. Typically additional information (metadata, such as responsible
organizations, a human readable name, a description of the object, and other information that is needed
for any meaningful use of the object identified) associated with the OID is stored also. With that, a
registry is then an OID repository at the same time.
Maintaining the list (and associated metadata) happens regardless whether it is an official register for
allocations of new OIDs under a given OID arc, or just a copy of information from other registries.
Official OID registries/repositories responsible for allocations of new OIDs under a given OID arc are
Registration Authorities.
4.2 Registration Authority (RA)
An RA is responsible for allocating child arcs to the OID that it manages (issuing authority). It ensures
that an integer is used once among the subsequent arcs (child OIDs). As much as possible, it avoids the
same identifier (beginning with a lowercase letter) being used for multiple sub-arcs. Such information
is typically stored in the OID registry/repository but it is important to understand that an OID first
needs to be officially allocated by an RA before it can be described in an OID repository
For each child OID, the RA also keeps a record of additional information (like the name of a contact
person, postal address, telephone and fax numbers, email address, etc.) about the Responsible Authority
for that child OID. A responsible authority for a child OID must formally become an RA for the child OID
in order to allocate sub-arcs under it.

ISO/TS 13582:2015(E)

4.3 Responsible (Managing) Authority (MA)
An MA is used to indicate the person (if known) and organization who is currently in charge of managing
the OID. Once a responsible authority is allocating sub-arcs and registering information on these sub-
arcs, it also becomes the Registration Authority for these sub-arcs.
Discussion: simply managing an OID (for example, for a code system) is the task of a Responsible
Authority MA. Potentially, a responsible authority may become a Registration Authority (RA) for a sub-
arc if it allocates sub-arcs.
4.4 Submitting Authority (SA)
This information is optional and reflects the person or organization that submitted the original OID
allocation request.
4.5 Current Registrant
In some OID registries, Current Registrants are stored. The Current Registrant is used to indicate the
person (if known) who is currently in charge of managing the OID, allocating sub-arcs and registering
information on these sub-arcs.
4.6 First Registrant
In some OID registries, First Registrants are stored. The First Registrant is used to indicate the very first
person (if known) who was responsible for managing the OID and who created it in the first instance.
This Technical Specification strongly suggests distinguishing between:
— a Registration Authority (RA) (person, if known, and organization) who issued (=allocated the
instance of) an OID and
— a Submitting Authority (SA) who submitted the OID allocation request (which may be the same instance).
In this sense, the First Registrant is the Registration Authority (RA).
4.7 First Registration Authority
The first Registration Authority of an OID is the very first person or company to whom the OID was
allocated by the RA of the superior OID. According to Rec. ITU-T X.660 | ISO/IEC 9834-1, the first RA
cannot be changed (if the responsibility is transferred to someone else, the information is recorded in the
“Current Registration Authority” section, without changing the “First Registration Authority” section).
Discussion: this is the Registration Authority (RA) that allocated the OID.
4.8 Rec. ITU-T X.660 | ISO/IEC 9834-1
In ITU-T Recommendation X.660, the following definitions are given.
— 3.6.8 registration authority: An entity such as an organization, a standard or an automated facility that
performs registration of one or more types of objects (see also International Registration Authority).
— 3.6.2 administrative role (of a registration authority): Assigning and making available unambiguous names
according to the Recommendation | International Standard defining the procedures for the authority.
— 3.6.14 technical role (of a registration authority): Recording definitions of the objects to which names are
assigned and verifying that these definitions are in accordance with the Recommendation| International
Standard defining the form of the definition.
This Technical Specification does not use administrative or technical roles.

5 Object identifiers in healthcare
5.1 General
OID (Object Identifiers) are unique identifiers for any kind of objects. They are defined in Rec.
ITU-T X.660 | ISO/IEC 9834-1. This identification system for objects and concepts makes reliable
electronic information exchange possible. Administration and Registration is regulated by a set of rules.
The precise designation of objects and concepts is a pre-requisite for the standardized exchange of
information. A globally unique identifier for each of these concepts will help to ensure international
exchangeability of objects within different applications (e.g. healthcare information systems). For
example, OIDs are often used within HL7 messages and documents and Rec. ITU-T X.509 certificates to
provide this unique identification.
In the exchange of healthcare information, especially between loosely coupled systems, additional
information about the object being identified is generally very beneficial; this is information that is
typically not contained in a transaction of data between systems but is reference information about the
objects contained in the transaction. There is a minimal set of such information, such as Responsible
Organizations, a human readable name, a description of the object, and other such information that
is needed
