==XML exchange format==
−
ss[-CC]
+
Data exchange can be facilitated by a standardized representation of the complete set of information as an 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.

==String ST==
+
The ISO rules on Secondary Arc Identifiers, as laid out in Rec. ITU-T | ISO/IEC 9834-1 ''Procedures for Registration Authorities'', section 6.2.2, apply:
−
A character string, with possible translations.
+
* identifiers of an arc are required to commence with a lowercase letter, and to contain only letters, digits, and hyphens.
 +
* the last characters shall not be a hyphen
 +
* there shall be no two consecutive hyphens in the name

==String ST.NT==
+
====category====
−
A character string, with no translations allowed.

−
==Object Identifier (dot notation) ST.OID==
+
There are actually two main types of OIDs: ''leafs'' (id of an object), and ''nodes'' representing an ontological branch.
−
This is actually a character string without translation (ST.NT) with a certain pattern.
 
  
−
The pattern is:
+
The types of ''node'' OID may be
−
\{?\s*(0|[1-9][0-9]*)(\.(0|[1-9][0-9]*))*\s*\}?
+
* a registration authority (RA) or
 +
* a structure for the management of OIDs.
  
−
Example:
+
The proposal for sub categories of ''leaf'' OIDs are
−
<syntaxhighlight lang="xml">
+
* identifiers of an instance of an object (for example a person)
−
<oid value="1.2.3.4.5.0.6.7.8.9"/>
+
* namespace identifiers (for example code systems, value sets)
−
</syntaxhighlight>
+
{{NoteBox|
−
{{WorkBox|
+
In addition there are properties of OIDs that can reflect other business needs.
−
The string pattern needs to be checked.
+
These can be
 +
* tags (simple text)
 +
* other categorizations of the OID, coded or as text
 +
* "sub-types" of the OID
 +
For further information see ''[[#AdditionalProperty|AdditionalProperty]]''.

−
==Object Identifier (asn1 notation) ST.ASN1==
 
−
This is actually a character string without translation (ST.NT) with a certain pattern.
 
  
−
The pattern is:
+
====status====
−
\{?\s*(([a-z][a-zA-Z0-9\-]*\s*((\s*(0|[1-9][0-9]*)\s*\))?|(0|[1-9][0-9]*))\s*){2,}\s*\}?

−
The string pattern needs to be checked.
+
 
−
}}
+
====creationDate====
−
==Object Identifier (iri notation) ST.IRI==
+
 
−
This is actually a character string without translation (ST.NT) with a certain pattern.
+
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.
 +
 
 +
====realm====
  
−
The pattern is:
+
In some cases OIDs may apply to a specific county/realm only, e.g. the namespace identifiers for the US Social Security Number (SSN) or the Dutch Citizen Service Number (BSN) or the codes system representing ICD-10 International Classification of Diseases 10th Revision for the use in Germany only (ICD10gm).

'''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.<ref name="Fielding-Ch5">Chapter 5 of Fielding's dissertation is [http://www.ics.uci.edu/~fielding/pubs/dissertation/rest_arch_style.htm "Representational State Transfer (REST)"].</ref><ref>[http://tech.groups.yahoo.com/group/rest-discuss/message/6735 "Fielding discussing the definition of the REST term"]</ref>

A RESTful web service is implemented using HTTP and the principles of REST. It is a collection of resources, with four defined aspects:
+
==SubmittingAuthority==
−
* the base URI for the web service, such as <code><nowiki>http://oid.server.org/</nowiki></code>
+
This is a class representing the submitting authority that originally asked for a new OID.
−
* 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.
+
[[Datei:Oid-SubmittingAuthority.jpg | 600px]]

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

Information model

In order to exchange OID and their metadata between different registries and applications the following additional data items beyond the OID itself need to be taken under consideration (see also [1] [2]):

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

An information model with all classes, attributes and their properties aiming on a common understanding of the requirements of an OID registry has been created (Figure 1).

OID Registry Model (Draft)

XML exchange format

Data exchange can be facilitated by a standardized representation of the complete set of information as an 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.

Registry

This is the basic information about the OID-Registry hosting the OIDs.

Oid-registry.jpg

Attributes

Attribute Description DT Card Conf Length
validTime validity time interval IVL_TS 1..* mandatory -
scopedOIDs List of scoped root OIDs ST.OID 0..* optional 64
name Official name of the OID registry ST 1..1 mandatory 64
description Description of the OID registry, possible in multiple languages ED 0..* optional -

validTime

This is the validity time interval, i.e. the begin (and end) time when this registry is/was responsible for registering OIDs. This can be a list of intervals.

Conformance.svg rg-vt: A validTime element shall be present and of datatype IVL_TS with at least the low child element populated.

scopedOIDs

List of scoped root OIDs, i.e. the OIDs for which this OID registry is responsible for registration.

Conformance.svg rg-so: If the OID registry is responsible for issuing/registering a root OID, this OID should be listed in scopedOIDs.

name

Official name of the OID registry

description

A description of the OID registry, possible in multiple languages

Conformance.svg rg-ds: If at least one description element is present one of the description's language code shall be English (“en”, “en-US” etc.).

Associations

Association Description Class Card Conf
person Contact person(s) Person 1..* mandatory

    <person> ... </person>
    <hostingOrganization> ... </hostingOrganization>

    <oid> ... </oid>

</registry>

Oid

This class contains the registered OID and the associated meta data.

Oid-OID.jpg

Attributes

Attribute Description DT Card Conf Length
dotNotation registered OID, dot notation ST.OID 1..1 mandatory 64
asn1Notation ASN.1 notation ST.ASN1 0..1 optional 128
iriNotation IRI notation ST.IRI 0..1 optional 128
symbolicName symbolic name ST.SYMB 0..1 optional 128
category OID category CS 1..1 required -
status OID status CS 1..1 mandatory -
creationDate date of creation TS 0..1 optional -
realm countries CS 0..* optional -
description textual description ED 1..* mandatory -

dotNotation

The OID in dot notation of SNMP or ASN.1/XER.

Example: 

2.16.528

asn1Notation

The OID in ASN.1 notation with (optional) identifiers and numbers.

Examples: 

{joint-iso-itu-t(2) country(16) nl(528)}

{itu-t(0) recommendation(0) a(1)}
Information icon.svg Note that the surrounding curly brackets can be omitted.
Information icon.svg Note that this information is not necessarily entered by a human, this item maybe populated algorithmically.

iriNotation

The OID in Internationalized Resource Identifier[3] (IRI) notation.

Example: 

oid:/Country/528
Information icon.svg Note that this information is not necessarily entered by a human, this item maybe populated algorithmically.

symbolicName / Secondary Arc Identifier

A symbolic short name, unique among the siblings of the arc of the OID.

The ISO rules on Secondary Arc Identifiers, as laid out in Rec. ITU-T | ISO/IEC 9834-1 Procedures for Registration Authorities, section 6.2.2, apply:

  • identifiers of an arc are required to commence with a lowercase letter, and to contain only letters, digits, and hyphens.
  • the last characters shall not be a hyphen
  • there shall be no two consecutive hyphens in the name

Example 

nl

category

The type/category of the OID; enumeration, values see value set OIDcategories.

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)
Information icon.svg In addition there are properties of OIDs that can reflect other business needs.

These can be

  • tags (simple text)
  • other categorizations of the OID, coded or as text
  • "sub-types" of the OID
For further information see AdditionalProperty.

status

Status of the OID. This is an enumeration, for values see value set OIDstatusCodes

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.

realm

In some cases OIDs may apply to a specific county/realm only, e.g. the namespace identifiers for the US Social Security Number (SSN) or the Dutch Citizen Service Number (BSN) or the codes system representing ICD-10 International Classification of Diseases 10th Revision for the use in Germany only (ICD10gm). This can be indicated by realm which is either the code of country or "UV" for universal. For values see code system CountryCodes.

description

This element contains a free text description of the OID ("what is the OID?"). The text typically contains an explanation but also can contain:

  • explicit versioning aspects
  • licensing information
  • Intellectual Property rights information
  • trademarks.

This element is repeatable for each language.

The datatype ED allows for a thumbnail child element. A thumbnail may be populated describing a short description of the OID (sometimes referred to as identifier name).

Example: 

<description language="en-US" value="this is plain text as a long description">
   <thumbnail value="short text"/>
</description>
Information icon.svg Note that data type ED also reflects the aspect of language of the description (language code).
Conformance.svg oi-ds: There SHALL be one description instance with language code English (“en”, “en-US” etc.).
