Hi,

I found out another problem with incorrect data being returned:


Sparql Insert Into <http://test.org> { <http://linkedgeodata.org/triplify/node855074925> <http://linkedgeodata.org/property/addr%3Acountry> "Halle" .};

Sparql Insert Into <http://test.org> { <http://linkedgeodata.org/triplify/node855074925> <http://linkedgeodata.org/property/addr%3Astreet> "Halle" .};

Sparql Select Count(*) From <http://test.org> {?s ?p ?o .};

Gives:
@prefix ns0: <http://linkedgeodata.org/triplify/> .
ns0:node855074925 <http://linkedgeodata.org/property/addr%3Astreet> "Halle" ,
        "Halle"

Expected:
@prefix ns0: <http://linkedgeodata.org/triplify/> .
ns0:node855074925 <http://linkedgeodata.org/property/addr%3Astreet> "Halle" ; ns0:node855074925 <http://linkedgeodata.org/property/addr%3Acountry> "Halle" ,


Obviously the predicates <...addr%3Acountry> and <...addr%3Astreet> are considered equal in the output, and therefore only of these predicates is retained.

I filed in a similar bug report (which was fixed) somewhen at the beginning of this year, but I couldn't find it anymore.

The previous bug was about the same behaviour of missing predicates, if the predicate uris could not be separated into a namespace and name part (such as http://www.p1.org, http://www.p2.org)

So this bug seems to be the same, except that this time its about URIs containing special characters.

This bug also appears if the URI contains a '+' instead of a '%'.

In the doc for TTLP[1] it states
... 16 - Allows '/', '#', '%' and '+' in local part of QName ("Qname with path") ...

Since it is working properly with predicate URIs containing / and #, % and + might be only characters causing trouble?
