rdflib extension adding JSON-LD parser and serializer

Project description

This is an implementation of JSON-LD for RDFLib. For more information about this technology, see the JSON-LD website.

This implementation will:

  • read in an JSON-LD formatted document and create an RDF graph
  • serialize an RDF graph to JSON-LD formatted output

Installation

The easiest way to install the RDFLib JSON-LD plugin is directly from PyPi using pip by running the command below:

pip install rdflib-jsonld

Otherwise you can download the source and install it directly by running:

python setup.py install

Using the plug-in JSONLD serializer/parser with RDFLib

The plugin parser and serializer are automatically registered if installed by setuptools.

>>> from rdflib import Graph, plugin
>>> from rdflib.serializer import Serializer

>>> testrdf = '''
... @prefix dc: <http://purl.org/dc/terms/> .
... <http://example.org/about>
...     dc:title "Someone's Homepage"@en .
... '''

>>> g = Graph().parse(data=testrdf, format='n3')

>>> print(g.serialize(format='json-ld', indent=4))
{
    "@id": "http://example.org/about",
    "http://purl.org/dc/terms/title": [
        {
            "@language": "en",
            "@value": "Someone's Homepage"
        }
    ]
}

>>> context = {"@vocab": "http://purl.org/dc/terms/", "@language": "en"}
>>> print(g.serialize(format='json-ld', context=context, indent=4))
{
    "@context": {
        "@language": "en",
        "@vocab": "http://purl.org/dc/terms/"
    },
    "@id": "http://example.org/about",
    "title": "Someone's Homepage"
}
