idolum commented 1 year ago

As a follow-up to #317 it is requested, to add means to distinguish various types of external documents provided along with an item. External documents are covered by epo-cat:ProductSpecification.

Use cases

A seller wants to provide several documents along with an item, e.g., a printer. These documents are:

Peppol uses a document type code including the code list UNCL1001:

Proposal

As there is a hierarchy of documents already in the ePO, there a several options:

Either link epo-cat:ProductSpecification to a controlled vocabulary

epo-cat:ProductSpecification --- epo:hasDocumentType -- 0..1 --> epo-cat:document-type

This approach is preferred by CEN/TC 440/WG 5.

Or add several subclasses to the document hierarchy and link them with the item:

epo:Document <|--- epo-cat:cat:ProductSpecification <-- 0..1 -- epo:hasSpecification -- epo-cat:Item
              |--- epo-cat:Image <-- 0..n -- epo:hasImage -- epo-cat:Item
