by Fabian Klopfer , Mark Schubert on November 30, 2023

iiRDS is becoming increasingly popular in the industry and is being continuously developed by the iiRDS working group Development.  parson has contributed to iiRDS since the beginning and provides expert iiRDS services.

On November 10, 2023, the new version 1.2 of iiRDS was released. We summarize the most important new features and changes for you:

iiRDS 1.2 – the most important changes

Links to external classifications

  • External classifications that are not based on RDF can now be integrated into iiRDS. The classifications can be assigned to information units (e.g. topics), but also to product variants, product features, and components. The main purpose is to integrate metadata from these external classifications systems. Examples include ECLASS, CDD (IEC 61360), DCC (IEC 61355), and VDI 2770. This allows you to use the metadata of these standards without having to reproduce them in iiRDS.
Example for linking iiRDS and ECLASS in iiRDS version 1.2

Terminology information in iiRDS

  • Terminology information on the iiRDS metadata is now available in iiRDS. Preferred and forbidden terms are specified in a supplementary file. For this purpose, iiRDS uses the Simple Knowledge Organization System SKOS. SKOS is a standard for taxonomies that is supported by numerous systems. The integration of SKOS is a first step towards modeling terminological information in iiRDS in a standardized and more harmonized way.
Example for using SKOS vocabulary in iiRDS version 1.2

Harmonized terminology with IEC/IEEE 82079-1 and other changes

  • The definitions of iiRDS classes and objects have been completely revised to make them easier to understand and to facilitate the use of iiRDS. In addition, the terms and definitions in iiRDS have been harmonized with the IEC/IEEE 82079-1 standard.
  • There have also been numerous smaller updates: the documentation has been expanded, examples have been added, and bugs fixed. For example, the iiRDS classes have been made disjoint. That means that metadata concepts cannot overlap anymore, which makes iiRDS more robust.
