Error using the XML dataset from the Madrid-GTFS-Bench #56

Closed dachafra closed 3 years ago

Running the SDM-RDFizer over the Madrid-GTFS-Bench using the XML distribution, we notice that the number of results obtained is not correct. Seems the problem is in the indexing step of the predicates, as it is removing many valid triples.

Number of expected results: 395953 Numer of obtained results: 337445

The problem is in the shape triplesMap, with the property http://vocab.gtfs.org/terms#shapePoint Attached find the mapping and the related data. gtfs-xml.zip
