Buyer main activity in case of multiple buyers

Rule Definition

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

Additional Information

Rule elaboration

For the simplification of the Buyer Main activity, 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 Main activity related to the notice through the path: (epo:Notice) -> [announcesRole = epo:Buyer] -> epo:playedBy (org:Organization) -> epo:hasMainActivity.
• A construct query is used to add the triple that links the epo:Notice with this Buyer Main activity.
