Winner country code in case of multiple winners

Rule Definition

In each lot where more than one winner country code is informed, the winner country code used for analysis is the first winner country code informed in each lot.

Additional Information

Rule elaboration

For the simplification of the Contractor Country Code, the following steps must be performed:

A lot award can be related to one or several epo:Winner, so for simplification purposes, only the first one is selected.
A SPARQL query will be used to retrieve the Winner Country Code entities related to each epo:Lot associated with the epo:Notice, following the path:

epo:Notice -> epo:announcesLotAwardOutcome (epo:LotAwardOutcome) -> epo:comprisesTenderAwardOutcome (epo:TenderAwardOutcome) -> epo:indicatesAwardOfLotToWinner (epo:Winner)-> epo:playedBy (org:Organization) -> epo:registeredAddress (locn:Address) -> epo:hasCountryCode .

A construct query will be used to link the epo:Notice with the simplified Winner Country.
