yarrrml-translator

The tool translates mapping rules from YARRRML in a turtle-based serialization of RML or R2RML. The translation is based on the RML and YARRRML specifications.

Limitations

We are working on including the following features which are not yet implemented:

• Functions using the FnO Ontology

Installation:

pip install yarrrml-translator

Execution

To execute from command line run the following:

python3 -m yarrrml_translator -i path_to_input_yarrrml.yml -o path_to_output.ttl [-f R2RML]

-f R2RML is an optional parameter for translating input YARRRML into R2RML

If you want to include the module in your implementation:

• for translating RML mappings:

import yarrrml_translator
import yaml

rml_content = yarrrml_translator.translate(yaml.safe_load(open("path-to-yarrrml")))

• for translating R2RML mappings:

import yarrrml_translator
import yaml

R2RML_URI = 'http://www.w3.org/ns/r2rml#'
rml_content = yarrrml_translator.translate(yaml.safe_load(open("path-to-yarrrml")), mapping_format=R2RML_URI)
