Winner in case of multiple winners

Rule Definition

In each procedure where multiple winners are informed, the winner used for analysis is the first winner informed in the result notice for each lot

Additional Information

Rule elaboration

For the simplification of the Contractor, 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 epo:Winner 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).
A construct query will be used to link the epo:Notice with the simplified epo:Winner.

Rule implementation

(Provide only URIs of formal encodings of the rules for execution. These are typically URIs of SHACL rules or RML maps. Each URI should be provided on a new line with no additional information)
