What is an identification guide?

with No Comments

One of the three fundamental elements of achieving ISO 8000 data quality is the ability of the said data to “meet the stated requirement”. An identification guide as specified in ISO 22745 part 30 – or template as it is often referred to in the data cleaning industry – specifies a set of rules for describing items and thus forms the basis of the stated requirement.

Each item belongs to a class, the given name for an item of supply or an item of production. This class uses references to concepts defined in a data dictionary to meet the requirements of a particular data recipient.

Each term is assigned a term type as per ISO 22745 part 1 paragraph 5.2.  In this example the term (radial) tapered rolling bearing has a term type of class.

Term:(radial) tapered roller bearing
Definition:radial rolling bearing with tapered rollers as rolling elements - ISO 5593:1997(en), 01.06.04 - Rolling bearings - vocabulary

A class associated with a unique identifier may, in certain circumstances be enough to identify an item of production. However, in practical usage, the identification guide shall also contain a request for other information that may identify the item. These other terms are known by the term type property. Taken together the class names and the property names form an identification guide that is defined in the standard as the data specification, that is the syntax specified in ISO/TS 22745-30 and that uses concept identifiers from an open technical dictionary.

Taking the example of the bearing further, the identification guide for a tapered roller bearing may contain the following properties:

Series, Cone part number, Cup part number, Design units, Bearing weight, Cage type, Bore, Cup outer diameter, Cone width, Cup width, Bearing width. These terms should be available in the corporate dictionary of the manufacturer along with the appropriate definitions, and the source of those definitions, as in the example below.  The identification guide when completed shall be registered in an open technical dictionary to enable data to be exchanged with external trading partners.
