Buyer NUTS code in case of multiple buyers

Rule Definition

In each procedure where the buyer NUTS code is not provided or it is not valid, it is inferred from the NUTS code of the first buyer informed in the procedure.

Additional Information

Rule elaboration

For the simplification of the Buyer NUTS code, the following steps must be performed:

• A Notice can be related to one or several epo:Buyers, so for simplification purposes, only the first one is selected.
• Use a SPARQL query to retrieve the epo:Buyer Organization NUTS related properties: Path for NUTS of the Organization : (epo:Notice) -> [announcesRole = epo:Buyer] -> epo:playedBy (org:Organization) -> epo:registeredAddress (locn:Address) -> epo:hasNutsCode.
• A construct query is used to add the triple that links the epo:Notice with this Buyer Organization NUTS simplification.
