<http://dbpedia.org/ontology/endDate> <http://www.w3.org/2002/07/owl#equivalentProperty> <http://schema.org/endDate>. is incorrect. Both properties mean the same; however, the domain of schema:startDate is broader then dbo:startDate, so they should not be considered equivalent.

Indeed, dbo:startDate rdfs:range xsd:date and examination select * {?x dbo:startDate ?y} shows that's true. So changed to rdfs:subPropertyOf
