Features

• A lightweight "ORM" to handle Linked Data Resources and their Origins
• Written in python
• Dependencies: rdflib
• Stores everything in memory
• API is still subject to change
• Tests describe basic functionality

How to use it?

First, we create an Origin object:

import pprint import rdflib from ldtools import Resource, Origin

uri = "http://dbpedia.org/resource/Karlsruhe"

origin, created = Origin.objects.get_or_create(uri)

Process it, hopefully discovering more Origins in there (rdfs:seeAlso, owl:sameAs...):

origin.GET(only_follow_uris=[rdflib.OWL.sameAs,rdflib.RDFS.seeAlso])

If everything went well, there now is a Resource object for our uri:

resource, created = Resource.objects.get_or_create(uri, origin=origin) pprint.pprint(resource.__dict__)

Process all the other Origins we know about

Origin.objects.GET_all()

Result: 5 URIs crawled and 500 Resources discovered and processed.
