Error parsing the GTFS-Madrid-Bench mapping

[dachafra]

Hi! We are trying to execute the RMLStreamer with the mappings and data from the GTFS-Madrid-Benchmark and we are obtaining an error through the parsing of the RML mapping. The mapping and data run perfectly in the RMLMapper or the SDM-RDFizer. (See in the attachment a zip containing the mapping and input CSV files scale 1).

Hi David, Thanks for reporting this. I'll have a look and come back to you.

Hi @dachafra , The error you posted should be fixed on the development branch, but is not released yet (related to #19 ). If you want to test, you can build from source or I can provide a jar file. I tried it with parameters toFile --mapping-file path/to/mapping-gtfs.rml.ttl --output-path /tmp/output and that seems to work. Let me know if you need more help. Best regards, Gerald

[dachafra]

Could you send me the jar please? here or by email to dachafra@gmail.com, it will be awesome! thank you very much

[ghsnd]

Here it is. Good luck!

[ghsnd]

Mind that you need Flink 1.11.3 for it to run properly.

[dachafra]

1.11.3 or 1.11.2? I saw in the documentation that the version needed is 1.11.2

[dachafra]

forget it, it seems that I don't know how to read properly, thanks!

[dachafra]

solved!
