What steps will reproduce the problem? The following code fails: graph=SPARQLGraph(Graph()) graph.parse('test.rdf')

where = GraphPattern([("?x",URIRef('http://xmlns.com/foaf/0.1/name'),"?name")]) constructPattern = GraphPattern([(URIRef("http://example.org/person#Alice"),URIRef('http://www.w3.org/2001/vcard-rdf/3.0#FN'),"?name")]) resultObject = Query.queryObject(graph,where) result = resultObject.construct(constructPattern)

What is the expected output? What do you see instead? Expected output: No error

Actual output: Traceback (most recent call last): File "sparqlinfer.py", line 44, in ? infer('test.rdf','rules.txt') File "sparqlinfer.py", line 40, in infer r=q.construct() File "/var/lib/python-support/python2.4/rdflib/sparql/Query.py", line 799, in construct subgraph = SPARQLGraph() TypeError: init() takes at least 2 arguments (1 given)

What version of the product are you using? On what operating system? Version 2.4.0, Debian "lenny"

Please provide any additional information below. Changing line 799 in /var/lib/python-support/python2.4/rdflib/sparql/Query.py to "subgraph = SPARQLGraph(rdflib.Graph.Graph())" fixes the problem.

Comment 6 by eik...@gmail.com These issues involve bits that have been moved out of rdflib proper for now. We will re-open them or move them to rdfextas as appropriate.
