success with diff/delta in RDF calendar testing work

I'm working on yet another rdf-to-ical conversion,
and the round-trip graph-match was failing, and I wanted
to know why. I've been disappointed by earlier versions
of diff.py, but it worked quite nicely this time:


connolly@dirk:~/w3ccvs/WWW/2002/12/cal$ python
~/w3ccvs/WWW/2000/10/swap/diff.py  --from test/spec01-conf3.rdf
--to ,xxx.rdf
     @prefix : <#> .
     @prefix cal: <http://www.w3.org/2002/12/cal/ical#> .
     @prefix delta: <http://www.w3.org/2004/delta#> .

     @forAll :_g0,
                :_g1 .
    {

        }     delta:deletion {<test/spec01-conf3.rdf#uid1@host.com>
cal:description """Networld+Interop Conference and Exhibit
Atlanta World Congress Center
 Atlanta, Georgia""" .
        };
         delta:insertion {<test/spec01-conf3.rdf#uid1@host.com>
cal:description "Networld+Interop Conference and Exhibit Atlanta World
Congress Center Atlannta, Georgia" .
        } .
    {
        <test/spec01-conf3.rdf#uid1@host.com>     cal:organizer :_g0 .

        }     delta:deletion {:_g0     cal:calAddress
<mailto:jsmith@host.com> .        } .
    {
        <test/spec01-conf3.rdf#uid1@host.com>     cal:organizer :_g1 .

        }     delta:insertion {:_g1     cal:calAddress
<test/spec01-conf3.rdf> .        } .
