Java-based command line software with the aim of converting rdf files from nquads format to json files following datacite schema (https://github.com/datacite/schema/blob/master/source/json/kernel-4.3/datacite_4.3_schema.json). It takes as input a folder containing nquads file generated by bmuse (https://github.com/HW-SWeL/BMUSE) and assumes that every .nq file is related to one single scraped url.

Command line RDF converter
===================================
usage: ./rdf-converter-cmdline.jar [-h] [-i] <arg> -o <arg> [-j] [-v] [-vv]
[-z]
-h,--help help
-i,--input <arg> the input directory that must contain .nq files (REQUIRED)
-o,--output <arg> the output directory (REQUIRED)
-j,--jsonld print input data with json-ld format
-v verbose
-vv show debug logs
./rdf-converter-cmdline-2.3.4.RELEASE.jar -i /tmp/rdf-converter-input/ -o /tmp/rdf-converter-output/ -j
The command above performs the following actions
- foreach file stored in nquads format in the given input path (-i) generates a json file following datacite schema in the given output path (-o)
- for each conversion a json-ld file will be printed on standard output corresponding to the input file data
