This rdflib plugin is deprecated for, as of the 2021-09-17 release of rdflib 6.0.1, JSON-LD handing has been integrated. All functionality in this package has been removed, as of release 0.6.2.
This plugin is now 'tombstoned' meaning this - 0.6.2 - is a final release and all users of Python > 3.6 are encouraged to move to rdflib > 6.0.1.
If you are forced to keep using Python <= 3.6, you will need to keep using release <= 0.5.0 of this plugin with RDFlib 5.0.0.
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
The easiest way to install the RDFLib JSON-LD plugin is directly from PyPi using pip by running the command below:
pip install rdflib-jsonldOtherwise you can download the source and install it directly by running:
python setup.py installThe plugin parser and serializer are automatically registered if installed by setuptools.
>>> from rdflib import Graph, plugin
>>> from rdflib.serializer import Serializer
>>> testrdf = """
... @prefix dcterms: <http://purl.org/dc/terms/> .
... <http://example.org/about>
... dcterms: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": [
