Annex A (informative)

In informative Annex A, a description possible of sub trees reflecting OID categories for e-health related OIDs is given.

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.

HL7 Viewpoint

HL7 International has created a type ontology for the OIDs in the HL7 registry to make it easier for the user community to search for OIDs they may be looking for. This type has nothing to do with ISO standards, or any intrinsic meaning or form of the OID itself. It is only a convenience for the users of this Registry.

The following Types have been defined for use in the HL7 OID Registry:

Arc	Type	Description
.1	HL7 registered internal objects (other than organizational bodies)	Type 1 OIDs are used for certain internal administrative functions, and to identify released and published Standards. This includes Version 3 International Releases, Normative Editions, V2.x Standards releases, CDA releases, etc. This is almost never used at this time.
.2	HL7 organizational bodies and groups	Type 2 OIDs are only used to identify an HL7 Group, such as a Working Group, or an International Council Member of HL7, such as HL7 Australia. These are created only when a new organizational body is recognized by HL7 International Headquarters.
.3	External (not HL7) group functioning as a Registration Authority	Type 3 OIDs are used for organizations that wish to create their own trees of OIDs for their use. If you will be assigning OIDs yourself under the OID that you are applying for, then you should select Type 3. This effectively delegates Registration Authority to your organization for all OIDs under this new Type 3 OID. No one else anywhere will create OIDs under your new root. Every OID created ‘under’ this new root will be considered by HL7 to be an ‘external’ OID, since you will have created it external to the HL7 OID Registry OID assignment software. These may be requested or registered by anyone. Note that a Type 3 OID identifies an organizational entity, not a particular piece of hardware machinery. It does not have to be a corporation, it could be as small as a single development group building interface software for an NHIN Connect project, for instance. Type 3 OIDs should not be used to identify objects in addition to the organizational entity responsible for creating new OIDs under it.
.4	Registered externally maintained identifier systems and namespaces	Type 4 OIDs are used for namespaces for identifiers that are public, and used widely, such as health card numbers, ID numbers assigned by jurisdictional authorities, etc. This is also used for any namespaces you may manage with your own defined OIDs under your own root, such as Medical Record Numbers or Accession Numbers, for example. This type of OID is typically used in the root of the version 3 datatype Instance Identifier.
.5	HL7 Internal Code Systems	Type 5 OIDs are used only for HL7 created and maintained Coding Systems, that have been approved through the HL7 V3 Harmonization process. This type is assigned only by the group that applies decisions from the harmonization processes to the HL7 databases. These OIDs are typically used in the codSystem property of an HL7 Version 3 coded datatype.
.6	Registered external coding systems	Type 6 is assigned to those OIDs that identify a Coding System or terminology that is created, published, and maintained by any organization outside of HL7. At this time, only an HL7 cochair or OID administrator can assign Type 6 to any OID. This type of OID is typically used in the codeSystem property of an HL7 Version 3 coded datatype.
.7	HL7 published document artifacts	Type 7 OIDs are used solely for HL7 published artifacts (not releases of Standards), and are assigned only by members of the HL7 publishing group. This includes tutorial slides, implementation guides, databases, published RIM graphic billboards, Wiki pages, etc.
.8	(deprecated)	Type 8 is currently not used.
.9	HL7 Registered conformance profiles	Type 9 is used to indicate HL7 Conformance Profiles, published in the HL7 Profile Registry.
.10	HL7 Registered Templates	Type 10 OIDs identify published Templates. These are created and registered by the Templates Workgroup, or by HL7 Workgroups that define and publish templates as part of their balloted standards.
.11	HL7 defined and registered Value Sets	Type 11 OIDs identify Value Sets that have been created and published by HL7, and have been approved through the HL7 Harmonization processes only. These are used in HL7 Version 3 Model Binding and Context Binding mechanisms, and can only be assigned by members of the group that applies the HL7 Harmonization process approvals to the HL7 databases.
.12	HL7 Version 2.x tables	Type 12 indicates that an OID identifies explicitly an HL7 Version 2.x Table, as published in the HL7 Version 2 series of standards. These exist to help facilitate development of translation capabilities between Version 2.x and Version 3/CDA interfaces.
.13	Externally authored and curated Value Sets	Type 13 OIDs identify Value Sets that have been created, published, and are maintained by organizations outside of HL7. They may be registered by anyone, and are generally used in Hl7 Version 3 Model Binding and Context Binding mechanisms.
.14	Assignment Ontology node	Type 14 OIDs may be used by any Registration Authority to indicate a structural ‘branch’ in the tree that they create under their own root, where the node is not any particular type of OID, the types will be below this node. Normally any node that is not a leaf is a registration authority, but some find that adding levels in the structure of the OIDs they create as Registration Authorities make the administration of the tree a bit easier. Each of the nodes in the HL7 tree that is the root of each of the Types is actually a Type 14 OID.
.15	Small code sets externally defined	Type 15 OIDs are used to identify small code lists or sets that are defined and maintained by organizations outside of HL7. Where Value Sets are built upon underlying coding systems, short code lists are often ad-hoc values that are used in various applications, that are not components of a particular terminology or coding system. This type of OID may be used in the codeSystem property of a version 3 coded datatype.
.17	Non-specified type	Type 17 OIDs are for any other type of object that does not fall into one of the other Type categories.
.18	HL7 Version 2.8 Coding Systems	Type 18 OIDs are specifically for those coding systems that are defined as such in the HL7 Version 2.8 standard. These may only be created by HL7 cochairs.
.19	HL7 Examples	Type 19 OIDs are used for published examples; it is a truly meaningless identifier, as it is not to be used for any actual entities. This is the only kind of OID that may not be a unique identifier, i.e. it may refer to more than one object if it appears in different publications or slides. Type 19 OIDs are used ONLY in published examples in documents and slide presentations, and should NEVER appear in any implementation or any HL7 model instance.

ObjectType

Type of object identified by the OID.

HL7 International makes a suggestion for a structure of object types

• .1 HL7 registered internal objects (other than organizational bodies)
• .2 HL7 organizational bodies and groups
• .3 External (not HL7) group functioning as a Registration Authority
• .4 Registered externally maintained identifier systems and namespaces
• .5 HL7 Internal Code Systems
• .6 Registered external coding systems
• .7 HL7 published document artifacts
• .9 HL7 Registered conformance profiles
• .10 HL7 Registered Templates
• .11 HL7 defined and registered Value Sets
• .12 HL7 Version 2.x tables
• .13 Externally authored and curated Value Sets
• .14 Assignment Ontology node
• .15 Small code sets externally defined
• .17 Non-specified type
• .18 HL7 Version 2.8 Coding Systems
• .19 HL7 Examples

From a policy perspective it is common practice in several healthcare related (European) OID registries and makes sense to distinguish at least between the following types of OIDs:

• .3 organizational bodies and groups
• .4 identifier systems
• .5 code systems
• .7 documents
• .9 conformance profiles
• .10 templates
• .11 value sets
• .19 examples
• .99 experimental

Basic interactions between OID registries

A set of basic interactions is developed and documented in order to facilitate the exchange of OID-related information between registries. This will include at least the following transactions:

• Share OID list
• Retrieve OID list

RESTful Web Servcies for an Object Identifier Resolution System

Representational state transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. The term representational state transfer was introduced and defined in 2000 by Roy Fielding in his doctoral dissertation.

A RESTful web service is implemented using HTTP and the principles of REST. It is a collection of resources, with four defined aspects:

• the base URI for the web service, such as http://oid.server.org/
• the Internet media type of the data supported by the web service, in this case either XML or HTML only.
• the set of operations supported by the web service using HTTP methods, in this case GET only.

Simple mechanisms should be provided in order to retrieve lists of OIDs from a registry, details of a particular OID or an extract of the entire OID registry. Various formats should be supported like HTML and the original XML format.

The suggested calls should be implemented as RESTful Web Services and their parameters are stated as follows.

Resource	Description GET	Parameters
OIDIndex	retrieves an index of all OIDs in the OID registry in HTML format	format (default, fixed): html id (optional): an OID language (optional): language
	http://oid.server.org/OIDIndex gets an HTML table of all OIDs in the registry with links to the details for each OID http://oid.server.org/OIDIndex?id=1.0.3166.1.2.2 gets an HTML table of OID 1.0.3166.1.2.2 with links to the details for this OID http://oid.server.org/OIDIndex?id=1.0.3166.1.2.2&language=de-DE gets an HTML table of OID 1.0.3166.1.2.2 with links to the details for this OID in the German language
RetrieveOID	retrieves a particular OID in the OID registry	id (required): an OID format (optional): html or xml language (optional): language
