Bug 1295098

When I install python3-rdflib and try to run the basic example from http://rdflib.readthedocs.org/en/stable/gettingstarted.html

    import rdflib
    
    g = rdflib.Graph()
    result = g.parse("http://www.w3.org/People/Berners-Lee/card")
    
    print("graph has %s statements." % len(g))
    # prints graph has 79 statements.
    
    for subj, pred, obj in g:
        if (subj, pred, obj) not in g:
            raise Exception("It better be!")
    
    s = g.serialize(format='n3')

I get:

    Traceback (most recent call last):
      File "./querytool.py", line 3, in <module>
        import rdflib
      File "/usr/lib/python3.4/site-packages/rdflib/__init__.py", line 108, in     <module>

    ImportError: No module named 'isodate'

Version-Release number of selected component (if applicable):
Everything from python3-rdflib-4.1.2-3.fc21 to 4.1.2-5.fc24.

The problem is that python3-rdflib has no python3-xxx dependencies.
