otsrdflib 0.1.0

Ordered Turtle Serializer for rdflib

An extension to the rdflib Turtle serializer that adds order (at the price of speed). Useful when you need to generate diffs between Turtle files, or just to make it easier for human beings to inspect the files.

$ pip install otsrdflib

Usage:

from rdflib import graph
from otsrdflib import OrderedTurtleSerializer

my_graph = Graph()

out = open('out.ttl', 'wb')
serializer = OrderedTurtleSerializer(my_graph)
serializer.serialize(out)

Subjects are grouped by class membership. The order of classes is configured through serializer.topClasses. A default list is provided to have e.g. SKOS.ConceptScheme classes appear before SKOS.Concept:

serializer.topClasses = [SKOS.ConceptScheme,
                       FOAF.Organization,
                       SD.Service,
                       SD.Dataset,
                       SD.Graph,
                       SD.NamedGraph,
                       ISOTHES.ThesaurusArray,
                       SKOS.Concept]
