I think the tags related to the Congresso Nacional do Brasil (name, wikidata=Q949699, wikipedia) should be moved from the building way ( https://www.openstreetmap.org/way/124198934 ) to the building relation ( https://www.openstreetmap.org/relation/7380938 ) and the building way should be marked with name="Palácio Nereu Ramos" + wikidata=Q4155889 .
