Describe the bug

2023-05-04 19:08:11,348 | INFO: Translating YARRRML mapping to [R2]RML
2023-05-04 19:08:11,348 | ERROR: ERROR: The YARRRML mapping has not been translated
2023-05-04 19:08:11,349 | ERROR: can only concatenate str (not "list") to str

To Reproduce
python3 -m yatter -i yarrrml_mappings_cf_2016_v2.yaml -o test.ttl

Expected behavior
Mappings is translated into RML (it works with Matey)

Hi @dgarijo,
The issue has been solved at dev branch. I'll generate a new release today for including the last fixes. In any case, here is the output of the translation.

btw, do you mind if I include this mapping as part of the testing?

commented

Please do. If you want more tests, now they also include some language tags: https://github.com/TEC-Toolkit/cfkg/blob/main/BEIS-UK/mappings/yarrml/yarrrml_mappings_cf_2016_v2.yaml

thanks!
