DIN EN 62656-1:2015-12

Part 1 of the group 62656-1, -2, -3 describes the logical structure for a set of spreadsheets, used as "data parcels", to define, transfer and register product ontologies. The logical data structure specified here is called "parcel structure" for short and can 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. This structure is designed and suitable for continuous expansion. Also shown for data exchange is a standard mapping between the meta-data of dictionary parcels in the spreadsheet format conforming to this standard and on the other hand the meta-data represented in IEC 61360-2 compliant EXPRESS model for dictionary exchange. IEC 62656-1 is closely linked to ISO 13584-35. In contrast, it is characterized by its more general, that is to say also more extensive system, and therefore also allows extensions and further developments of the meta-lexicon, the metaclasses. Specifically, the spreadsheet interface structure includes specifications and specifications for: - logical structure and layout of the spreadsheet interface for definition, transfer, and registering of a reference dictionary; - library instance data belonging to a class of a reference dictionary; - this meta dictionary that enables the definition and transfer of a reference dictionary as a set of instance data conforming to the meta dictionary; - the meta-model as data that enables the definition and transfer of a reference dictionary as a set of instance data conforming to the meta-meta reference dictionary; - the mapping between the dictionary data expressed in the spreadsheet formats and the EXPRESS model specified by IEC 61360-2 / ISO 13584-42 (with some elements of ISO 13584-25); - the basic semantic mapping between the dictionary data expressed in the spreadsheet formats defined in this part of IEC 62656.
