ISO/DIS 16757-4

Data structures for electronic product catalogues for building services — Part 4: Dictionary structures for product catalogue ISO/DIS 16757-4

Scope

The focus of ISO 16757 is the support of manufacturers to provide their product data in electronic product catalogues. The standard - ISO 16757 Part 4: Dictionaries for product catalogues – describes which data structures are required in a dictionary to support the exchange of product data from manufacturers to designers of building services systems.

Basis for this specification are the standards ISO 12006-3 and ISO 23386.

In the scope of this standard are the following elements:

- The definition of roles of ISO 12006-3 subjects that are needed to describe the concepts used in current product catalogue dictionaries. These roles include the following:
o Product classes to represent product groups with similar property sets
o Blocks that represent reusable and multiply used set of properties
o System classes that represent the systems into which a product may be installed and provide the system properties which determine the values of dependent product properties
o Port classes that allow the product independent description of different kinds of ports which can be used for the definition of product classes or blocks
o Catalogue classes that describe the meta data of a catalogue
o Tagging classes that allow the tagging of properties to distinguish property roles in the product description
- A requirement model capturing the necessary structures to describe these roles
- A mapping to the dictionary model of ISO 12006-3.
