scope:

The primary purpose of NEN-ISO 16757-1 is the provision of data structures for electronic product catalogues to transmit building services product data automatically into models of building services software applications. This includes a meta model for the specification of product classes and their properties and a meta model for the product data which is exchanged in product catalogues. Product data has to follow the specifications for their product groups. The standard series is split into two areas: - Basic concepts like conceptual models, languages, geometry representations, and XML schemas for data exchange are provided in the Conceptual Parts of the standard series (Parts with a one digit number). - Using these resources, the Content Parts of this International Standard define for various product groups of building services concrete models for the description and the exchange of products.
