Standardized product ontology register and transfer by spreadsheets - Part 1: Logical structure for data parcels
 N EN 62656-1

Annotation

This part of IEC 62656 specifies the logical structure for a set of spreadsheets, used as "data parcels", to define, transfer and register product ontologies. Such ontology descriptions in other literatures or disciplines are sometimes called "reference dictionaries". Thus the logical data structure described in this standard is named "Parcellized Ontology Model" or "POM" for short, and each vehicle of transport of the model is called a "parcel", and may be used for definition, transfer, and registering of a reference dictionary as a collection of metadata, or for similar purposes for instances belonging to a certain class of the reference dictionary. Moreover, this ontology model allows for modelling or modifying an ontology model per se as a set of instance data, thus it enables an ontology model to evolve over time.

This part of IEC 62656 also includes a standard mapping between the meta-data of dictionary parcels in the spreadsheet format conforming to this standard and the meta-data represented in IEC 61360-2 compliant EXPRESS model for dictionary exchange.

It is assumed that a tool supporting this part of IEC 62656 may read and write a set of spreadsheet data whose semantics and syntax are defined in this part of standard, where the physical file structure of the spreadsheets may be based on the CSV (Comma Separated Values) format, typically used in a commercial spreadsheet application, or any other tabular formats including XML schema compatible or convertible to the CSV format.

The spreadsheet interface structure defined in this part of IEC 62656 contains the following:

– Definition and specification of the logical structure and layout of the spreadsheet interface for definition, transfer, and registering of a reference dictionary;
