ISO 22745 consists of the following parts under the general title Industrial automation systems and integration — Open technical dictionaries and their application to master data:
Part 1, Overview and fundamental principles;
Part 2, Vocabulary;
Part 10, Dictionary representation;
Part 11, Guidelines for the formulation of terminology;
Part 13, Identification of concepts and terminology;
Part 14, Dictionary query interface;
Part 20, Procedures for the maintenance of an open technical dictionary;
Part 30, Identification guide representation;
Part 35, Query for characteristic data;
Part 40, Master data representation;
Part 50, Registration of open technical dictionaries;
Part 200, Implementation guide for incorporating master data into ISO 10303 product data;
Part 300, Master data guides.
Part 1 includes the following:
requirements that all OTDs must satisfy;
description of the OTD data architecture;
properties of items of supply and items of production;
overview of ISO 22745.
Part 2 includes the following:
terms related to open technical dictionaries and their application to master data.
Part 10 includes the following:
conceptual model of an OTD;
XML schema for an XML physical file for computer-to-computer exchange of OTDs.
Part 11 includes the following:
guidelines for the formulation of terms;
guidelines for the formulation of definitions.
NOTE 1 A term or definition need not conform to the guidelines of ISO 22745-11 in order be included in an OTD. However, if it does, it will be marked as conformant.
Part 13 includes the following:
general requirements for identifiers;
syntax of identifiers.
Part 14 includes the following:
minimum set of services provided by an OTD implementation;
abstract definition of a query interface that must be supported by an OTD;
Web services binding of the query interface.
Part 20 includes the following:
description of the dictionary maintenance organization (DMO);
rules for release of an OTD;
procedure for updating the restrictions on the use of terminology terms and definitions within an OTD.
Part 30 includes the following:
Part 35 includes the following:
conceptual model for queries of characteristic data;
exchange format for queries of characteristic data.
Part 40 includes the following:
conceptual model for master data;
exchange format for master data.
Part 50 describes the structure and operation of a registration authority (RA) that maintains a list of OTDs.
NOTE 2 Such a RA only maintains a list of OTDs, not the contents of a specific OTD.
Part 200 includes the following:
overview for implementers of how catalogue data are represented in ISO 10303;
general requirements for representing catalogue data in a data set that conforms to an ISO 10303 application protocol (AP);
a reference to the "Simplified cataloguing" module, which may be used to incorporate the ability to represent OTD catalogue data into modular APs;
guidelines for writing OTD catalogue data to a data set that conforms to an ISO 10303 AP;
guidelines for extracting OTD catalogue data from a physical file conforming to an ISO 10303 AP.
Part 200 is intended to provide guidance to implementers but not supersede the requirements contained within the ISO 10303 APs themselves.
Part 300 includes the following:
generic templates for commonly-used types of master data;
EXAMPLE Organization, location, and person are commonly-used types of master data.
mapping from the templates to ISO/TS 22745-30 IGs;
requirements for conformance of ISO/TS 22745-30 IGs to the templates.
