ISO 22745-20:2010(E)

Introduction

ISO 22745 specifies a system for descriptive technology consisting of:

An OTD is a collection of terminology defined by and obtained from consensus bodies such as ISO, IEC, and other groups that have a consensus process for developing terminology. An OTD contains terms, definitions, and images of concepts used to describe individuals, organizations, locations, goods and services. Within ISO 22745, an item is described through membership in a class and a set of property value pairs.

An OTD:

Any consensus organization can submit terminology for inclusion in an OTD. ISO 22745 does not establish a new process for standardizing terminology. Each OTD will have a globally unambiguous identifier for each concept and provide a reference back to the original source for terminology (terms, definitions and images). OTDs are designed to link terms and definitions with the same semantic content and to reference the original source of each term and definition. Thus, OTDs are intended not to duplicate existing standards, but to provide comprehensive collections of terminology used to describe individuals, organizations, locations, goods and services.

Although the process for harmonizing terminology is outside the scope of ISO 22745, an OTD can serve as a useful research tool to aid the harmonization process, e.g., between ISO, IEC and other standards.

An IG specifies which concepts can be used and constrains which concepts can be linked to each other. An example for the latter is when an IG specifies the properties which can be linked to a class. Furthermore, an IG can specify which terms, definitions and images are applicable, in a case where there are multiple terms, definitions and images for concepts.

Master data is data held by an organization that describes the entities that are both independent and fundamental for that organization, and that it needs to reference in order to perform its transactions.

A catalogue is a representation of master data in the form of property value pairs.

See ISO 22745-1 for a more detailed overview of ISO 22745.

This part of ISO 22745 contains procedures for maintenance of an open technical dictionary (OTD).

The concept of operations for a dictionary maintenance organization (DMO) described in this part of ISO 22745 is that consensus organizations external to the DMO will standardize content then submit the content to the DMO for inclusion in the OTD. Since any request to add an entry to an OTD will contain terminology that has already been standardized by a consensus organization, it is not necessary for the DMO to perform a technical review before adding the entry to the OTD.
