ISO 10303-210 Industrial automation systems and integration -- Product data representation and exchange, Part 210: Electronic assembly, interconnect and packaging design, and ISO 10303 –212 Industrial automation systems and integration -- Product data representation and exchange, Part 212: Electrotechnical design and installation, is believed to cover the most urgent needs for product modelling. These models are using the EXPRESS modelling language. These standards were developed in a Joint Working group between ISO TC184/SC4 and IEC TC3.
An information model is also provided for the management and maintenance of data element types, in IEC 61360-2 Standard data element types with associated classification scheme for electric components - Part 2: EXPRESS Dictionary schema (the same model also documented in ISO 13584-42). This model is also development in EXPRESS.
IEC 61360-5 Standard data element types with associated classification scheme for electric components - Part 5: Extensions to the EXPRESS dictionary schema describes an extension that is not yet part of ISO 13584-42.
Information models are also provided for the management of technical documents, in IEC 82045-2 Document management, Part 2: Reference collection of metadata and reference models. This model is provided in three variants: EXPRESS, XML and a flat table.
