idolum commented 1 year ago

As follow-up to #380, an additional identifier is requested to be added to the epo-cat:Item:

Use case

A central purchasing body (CPB) compiles catalogues from various sellers. To harmonize the item identifiers, the CPB assigns identifier to each item from each seller. In addition, the sellers are asked to provide the identifiers in their provided catalogue assigned to their items by the CPB.

An example for such buy-side identifier can be found at

Proposal

Add an association

epo-cat:Item --- epo:hasBuyerItemID -- 0..1 --> epo:Identifier
