Creating RDF from DataFrame

As of version 1.1.0 NamespaceManager can be supplied to rdflib.to_graph for conversion to Graph.

from rdfpandas.graph import to_graph
import pandas as pd
import rdflib

df = pd.read_csv('to_graph_test.csv', index_col = '@id', keep_default_na = False)
namespace_manager = NamespaceManager(Graph())
namespace_manager.bind('skos', SKOS)
namespace_manager.bind('rdfpandas', Namespace('http://github.com/cadmiumkitty/rdfpandas/'))
g = to_graph(df, namespace_manager)
s = g.serialize(format = 'turtle')

Creating DataFrame from RDF

from rdfpandas.graph import to_dataframe
import pandas as pd
import rdflib

g = rdflib.Graph()
g.parse('to_df_test.ttl', format = 'ttl')
df = to_dataframe(g)
df.to_csv('test.csv', index = True, index_label = "@id")
