Handling urn : unsupported operand type(s) for +: 'NoneType' and 'unicode'

[ogirardot]

Hi,
I was trying to output a simple json-ld document from the following input :

@prefix lt: 
<urn:lt:onto:> .

<urn:lt:members:f.biville> a lt:Person;
    lt:email "test@gmail.com" .

And i got the following error at build/bdist.macosx-10.4-x86_64/egg/rdflib_jsonld/ldcontext.py in _rec_expand at the line 119 using latest master.

Context was :

nxt u'lt:onto:'
expr u'urn:lt:onto:'
is_term False
pfx u'urn'
prev None
data {'lt': u'urn:lt:onto:',
 'rdf': u'http://www.w3.org/1999/02/22-rdf-syntax-ns#',
 'rdfs': u'http://www.w3.org/2000/01/rdf-schema#'}
self    <rdflib_jsonld.ldcontext.Context object at 0x104c81950>

It seems that the converter is trying to match a "binded namespace : URN" which is a bit confusing.
What did i do wrong ?

Regards,

Olivier.

I think this is a symptom of my issue #10. Try changing IRI_KEY in ldcontext.py to ID_KEY.

This has been fixed.
