Usage

To execute the python module you can follow the following code to parse the RDF Turtle file to generate the JSON-LD content to be sent to the FIWARE Context Broker:

from sdmx2jsonld.transform.parser import Parser
from sdmx2jsonld.exceptions import UnexpectedEOF, UnexpectedInput, UnexpectedToken

file_in = open("structures-accounts.ttl")
generate_files = True

# Start parsing the file
my_parser = Parser()

try:
    my_parser.parsing(content=file_in, out=generate_files)
except UnexpectedToken as e:
    print(e)
except UnexpectedInput as e:
    print(e)
except UnexpectedEOF as e:
    print(e)

Where:

• file_in is the RDF Turtle content that can be a string in StringIO class or a read file in TextIOWrapper class.
• file_out is a boolean variable to indicate if we want to save the JSON-LD parser content into files (True) or we want to show the content in the screen (False).
