Scope

This International Standard specifies the mandatory and optional information to be recorded in any repository of OIDs, using an information model.

It specifies what parts of that information shall be regarded as public, and what parts shall be subject to security and privacy requirements.

In detail, this International Standard:

• specifies an XML format for the export of the contents of an OID repository, suitable for import to a different OID repository;
• specifies security procedures related to that export/import;
• references the 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.

Introduction

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 (see also ISO/NWIP/TR "Health Informatics – Guidance for maintenance of Object Identifiers OID").

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 for any meaningful use of the objects identified. Since such information may not be locally available to a system examining the communicated objects, it makes sense to have such information available in a standardized form, and accessed by using the OID to identify this information. Such information, referred to as the OID metadata, is the bulk of the information 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. Contents, attributes and rules of the assignment of OIDs of existing registries are incompatible and often dissimilar. Many registries still distribute OIDs in a form only suitable for direct text processing (like spreadsheets) that is error prone and hard to automate. There is a need to store and transfer collections of OIDs and also to keep some registries completely in sync, maintaining the contents and the structure of metadata of each of the registered OIDs e.g. descriptions, comments, versions, links, relations, responsible organizations and persons, etc.

Data exchange can be facilitated by a standardized representation of a required minimum set of metadata as an XML structure together with the associated checks of underlying constraints and business rules. This XML structure for importing and exporting OIDs amongst different registries should be achieved for supporting eHealth applications. In addition, the failure to have a standard for the operations needed to coordinated and synchronize the contents of disparate OID registries leads to confusion and ambiguity for the community that uses eHealth information containing references to objects identified by OIDs.

There are currently at least hundreds of OID registries in active use throughout the world. These are sponsored and operated by disparate entities, ranging from national governments, to individual companies or standards organizations, to individuals in a specialized area or industry. In many cases, more than one of these registries address the same industry segment, and have overlapping content, i.e. specific OIDs exist in both, or worse, different OIDs identifying the same object exist in both. This distributed set of disparate registries servicing a particular industry (specifically Healthcare IT) has led to awkward and error prone searching processes. To get information about existing OIDs, a search within all existing registries is needed, for example to avoid duplicate assignment of multiple OIDs to one and the same concept. In order to standardize the activities to synchronise all existing OID registries and to ensure further interoperability it is essential to have a defined exchange format and business rules for maintenance of the OID registries that must cooperate in a particular industry.

Some OID registries are operated by essentially volunteer organizations, such as Standards Bodies. The burden of administrative tasks is such that multiple individuals, often in different geographical locations, must participate to share the workload. Thus in addition to distributed Registry instances, administrative functions need to also be distributed, both on single and potentially across multiple Registries. There is a need for the standardization of a minimum set of administrative access and operational functions such that developers of Registries can deploy standard mechanisms to streamline and increase accuracy and productivity of these maintenance operations.

This NWIP is a proposal for a new document and describes a generic exchange format that will cover the minimal set of metadata and associated rules for OIDs of existing registries. It specifies principles and processes that should be explored/implemented by developers and data administrators of OID registries and their applicant bodies. The primary target group for this document are those establishing OID Registries and those (industry, government bodies) using the services maintained by such organizations.

Additional descriptions

A general description of the registration procedures for various parts of the object identifier tree, by reference to other specifications and links to other documents is given in ISO 13581 - Health informatics - Guidance for maintenance of object identifiers, OID - Technical Report.

Annex A is a specific description for the registration procedures for e-health related OIDs, and includes a specification of those parts of the OID tree that are known to be used for national and for international e-health applications.

Related work

This work is related to discussions about OID in the work programme of TC 215 WG3, HL7, ISO/IEC JTC 1/SC 6, ITU-T SG 17 and other organizations dealing with OIDs and OID registries.

Approach

Following an extensive analysis of the currently available international OID register for health care systems, a basic data set and a corresponding XML representation as an exchange format need to be created for registering and exchanging OID-related data. To collect the very basic requirements to such a format an analysis of several registers (e.g. HL7 International register and several European registers was performed so far (see Table 1). The analysis included the contents, attributes and even the rules of the assignment of OID.

Only a few of the registers specified an (XML-) exchange format. Due to lack of a common understanding of OID registry requirements, data fields must be mapped (manually) when OID information needed to be exchanged.

Definitions

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 a 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.

Registration Authority (RA)

A Registration Authority (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 need 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 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 is formally becoming a RA for that child OID, as it may allocate sub arcs.

Responsible Authority (MA)

A Responsible (Managing) Authority (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 subarcs and registering information on these subarcs, it also becomes the Registration Authority for these subarcs.

Submitting Authority (SA)

This information is optional and reflects the person or organization that submitted the original OID allocation request.

Relationship to definitions from other sources

Current Registrant

In some OID registries, Current Registrants are stored. The definitions from other sources say that the Current Registrant is used to indicate the person (if known) who is currently in charge of managing the OID, allocating subarcs and registering information on these subarcs.

First Registrant

In some OID registries, First Registrants are stored. The definitions from other sources say that the First Registrant is used to indicate the very first person (if known) who was responsible to manage the OID and who created it in the first instance.

Other sources: 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 can't 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).

Rec. ITU-T X.660 | ISO/IEC 9834-1

In ITU-T Recommendation X.660 the following defintions 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.

Use Cases

A list of OID Registry Use Cases has been defined in order to drive metadata model requirements, and functional requirements for Registry interoperability.

U6: OID Information Request

Search for a list of OID based on various sub-criteria, with and without wildcards

• Those registered by a particular entity
• Those associated with a type of information object
• Those associated with implementation guides
• Those registered during some time period
• etc.

Communication model

In order to exchange OID and their metadata between different registers and applications the following additional data items beyond the OID itself need to be taken under consideration (see also ):

• descriptions
• status information
• categorization
• time information
• comments
• versions
• links
• relationships to other OIDs and external sources
• registering and responsible organizations
• associated persons.

A communication model with all classes, attributes and their properties aiming on a common understanding of the requirements of an OID registry has been created.

XML exchange format

Data exchange can be facilitated by a standardized representation of the complete set of information as XML structure together with the associated checks of underlying constraints and business rules. This XML structure for importing and exporting OID amongst different registries and other healthcare applications is aiming on the availability of reliable information about OIDs.

The following sections summarise and explain classes and their attributes.

category

Type/category of OID, enumeration, values: OIDCategory

There are actually two main types of OIDs: leafs (id of an object), and nodes representing an ontological branch.

The types of node OID may be

• a registration authority (RA) or
• a structure for the management of OIDs.

The proposal for sub categories of leaf OIDs are

• identifiers of an instance of an object (for example a person)
• namespace identifiers (for example code systems, value sets)

status

Status of the OID. This is an enumeration, for values see: OIDstatus

creationDate

The creationDate is used to describe when the OID was first registered. It is not the date when the OID description is submitted to the OID repository. The creationDate, once set, never changes.
