gtfs:zone is an object property in the ontology but data property in the mappings

Hi David,

I just have a question about the mappings. From what I see in this mapping file (https://github.com/oeg-upm/gtfs-bench/blob/master/mappings/gtfs-rdb.r2rml.ttl), gtfs:zone seems to be a data property. However in the gtfs terms (https://github.com/OpenTransport/linked-gtfs/blob/master/gtfs.ttl), it is an object property.

So I just want to know if you have the latest ontology or gtfs terms that you used to define the mappings.

Thank you in advance.

Best,
Huanyu Li

Hi @huanyu-li,
You are right, we will update the mappings asap to generate a URI for the gtfs:zone. In any case, I think there are no values for that column (zone_id) on the original data, so you will never generate any RDF term/triple ;-)

OK, I see. Thanks for the reply.
