TS EN 62656-3

TS EN 62656-3 defines the interface between the 62656 family’s standardized product ontology register and transfer mechanism based on spreadsheets and the Common Information Model (CIM). It provides a formal mapping framework so that the CIM ontology can be imported into the IEC CDD environment and ontology interoperability can be supported across different standards.

Bridging CIM and product ontologies

In technical information modelling, CIM is a shared semantic framework used to describe entities and relationships in a consistent way, especially in power-system related data exchange. This standard focuses on mapping CIM to the data model defined in IEC 62656-1. In general technical terms, such mappings help align terminology, structure, and meaning so that ontology-based data can be exchanged without losing its conceptual consistency. Referencing the UML representation of CIM supports a formal, structured basis for that mapping.

Why spreadsheet-based transfer matters

Spreadsheets are widely used because they are accessible for humans while still being suitable for structured data handling. In the broader technical context, they can simplify data entry, review, and exchange between systems. Here, however, the emphasis is not on spreadsheets alone but on a standardized route for registering and transferring product ontology data in a way that can be mapped to CIM and related models. That distinction matters because the value lies in controlled semantic alignment, not just in file formatting.
