Hello @samuan2022,
Thank you for using SDM-RDFizer. I ran the mapping you gave me and had to fix the prefixes since they were not in the correct format for RDF. These are the corrected prefixes:
@prefix rr: <http://www.w3.org/ns/r2rml#> .
@prefix rml: <http://semweb.mmlab.be/ns/rml#> .
@prefix ql: <http://semweb.mmlab.be/ns/ql#> .
@prefix transit: <http://vocab.org/transit/terms/> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix wgs84_pos: <http://www.w3.org/2003/01/geo/wgs84_pos#> .
@base <http://example.com/ns> .
Afterward, I was able to find and fix the problem. Here is the result after the fix:
<http://airport.example.com/6523> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://vocab.org/transit/terms/Stop>.
<http://airport.example.com/6523> <http://vocab.org/transit/terms/route> "25"^^<http://www.w3.org/2001/XMLSchema#int>.
<http://airport.example.com/6523> <http://www.w3.org/2003/01/geo/wgs84_pos#lat> "50.901389".
<http://airport.example.com/6523> <http://www.w3.org/2003/01/geo/wgs84_pos#long> "4.484444".
Please test it out to ensure the problem was fixed on your side.
Sincerely, Enrique Igleisas
Hello Enrique
I fixed the prefixes and I update the software to version v4.7.4.5, but the problem continues.
This is the responde in the console:
python3 -m rdfizer -c ./configuracion.ini
Semantifying salida...
Traceback (most recent call last):

Hello again,
I was able to find the problem and fix it. I made sure to test out all possible combinations in the configuration file, and everything worked. Please test it out.
SIncerely, Enrique Iglesias
Hello
Now it works
Thank you very much
Great, I'll close the issue.
Describe the bug I'm trying to map from CSV to RDF. When launching the Rdfizer Software I get the following error: UnboundLocalError: local variable 'triples_map' referenced before assignment
To Reproduce
RML mapping document:
@prefix rr: http://www.w3.org/ns/r2rml#. @prefix rml: http://semweb.mmlab.be/ns/rml#. @prefix ql: http://semweb.mmlab.be/ns/ql#. @prefix transit: http://vocab.org/transit/terms/. @prefix xsd: http://www.w3.org/2001/XMLSchema#. @prefix wgs84_pos: http://www.w3.org/2003/01/geo/wgs84_pos#. @base http://example.com/ns.
<#TriplesMap> a rr:TriplesMap;
rml:logicalSource [ rml:source "datosbase.csv" ; rml:referenceFormulation ql:CSV ];
rr:subjectMap [ rr:template "http://airport.example.com/{id}"; rr:class transit:Stop ];
rr:predicateObjectMap [ rr:predicate transit:route; rr:objectMap [ rml:reference "stop"; rr:datatype xsd:int ] ];
rr:predicateObjectMap [ rr:predicate wgs84_pos:lat; rr:objectMap [ rml:reference "latitude" ] ];
rr:predicateObjectMap [ rr:predicate wgs84_pos:long; rr:objectMap [ rml:reference "longitude" ] ].
CSV Document:
id,stop,latitude,longitude 6523,25,50.901389,4.484444
Configuration.ini:
[default] main_directory: ./dataset
[datasets] number_of_datasets: 1 output_folder: ./graph all_in_one_file: no remove_duplicate: yes enrichment: no name: datosbase ordered: no output_format: turtle
[dataset1] name: salida mapping: ./reglas/reglas.ttl
Expected behavior
Data in RML format
