RDF is a standard model for data interchange on the Web, standardized by the World Wide Web Consortium (W3C).

The following table presents the allowed input and output RDF syntaxes. I.e., the RDF Syntax Converter can convert from and to the following syntaxes:

The software accepts as input any URL or file formatted in one of the mentioned syntaxes and generates a file with the desired target syntax as output.

This software is a simple implementation of an RDF syntax converter that relies on the RDFLib v6.2.0 capabilities. It was created for training purposes and, hence, no refinements were performed.

The software was not extensively tested and does not count with advanced errors and exceptions handlings or even non-standard use verifications. The software was developed in a Windows environment and was not tested in Linux or Mac.

You need to download and install Python for executing the RDF Syntax Converter. The code was developed and tested using Python v3.10.5.

Only two external libraries are necessary: RDFLib (v6.2.0) and Tabulate (v0.8.10). For installing these libraries, run the following command on the terminal:

pip install -r requirements.txt

After the external libraries are installed, run the following command on the terminal for executing the RDF Syntax Converter:

python rdfconv.py <input file OR URL> <output file>

While the input syntax is automatically detected by the RDF Syntax Converter, the target syntax is chosen via the output filetype (file extension) informed by the user as the software argument.

Converting a web RDF-based file to a JSON-LD file (saved in the same directory of the rdfconv.py file):

python rdfconv.py http://purl.org/nemo/gufo gufo.jsonld

Converting an OWL file formatted in XML/RDF to a Turtle (TTL) file (both input and output files are saved in the same directory of the rdfconv.py file):

python rdfconv.py ontology.rdf ontology.ttl
