About

This tool converts any xml file into a generic rdf model.

See the Data2Services documentation to run xml2rdf as part of workflows to generate RDF knowledge graph from structured data.

Docker

Build

docker build -t xml2rdf .

Usage

docker run --rm -it xml2rdf -?

Usage: xml2rdf [-?] [-xp] -g=<graphUri> -i=<inputFilePath> [-n=<namespace>]
               -o=<outputFilePath>
  -?, --help         display a help message
  -g, --graphuri=<graphUri>
                     Graph URI
  -i, --inputfile=<inputFilePath>
                     Path to input file (.xml or .xml.gz). Wildcards are also
                       supported. (see: Apache Ant DirectoryScanner)
  -n, --namespace=<namespace>
                     Namespace for data nodes.
                       Default: http://ids.unimaas.nl/xml2rdf/data/
  -o, --outputfile=<outputFilePath>
                     Path to output file (.nq or .nq.gz)
      -xp, --xpath   Generate XPath paths in output

Run

Linux / OSX

docker run --rm -it -v /home/d2s:/data xml2rdf  -i "/data/input.xml.gz" -o "/data/output.nq.gz" -g "http://kraken/xml2rdf/graph"

For a file on /home/d2s/input.xml.gz

Windows

docker run --rm -it -v c:/home/d2s:/data xml2rdf  -i "/data/input.xml.gz" -o "/data/output.nq.gz" -g "http://kraken/xml2rdf/graph"
