We need a Python3 version of python-isodate (per bug 1031321) and also want to update python-rdflib to the latest 4.1.x version (per bug 1070074) before we can add Python3 support to python-rdflib.

python-rdflib.spec

Attached spec file that builds python3-rdflib 
one changes the line of the previous spec file to 
Requires:      python3-rdflib

The trouble is -  
python3-selenium-2.40.0-2 depends on python-rdflib 
Bug 1116470 	

python3-rdflib and python-rdflib both install some files to
/usr/bin/csv2rdf
/usr/bin/rdf2dot
/usr/bin/rdfgraphisomorphism
/usr/bin/rdfpipe
/usr/bin/rdfs2dot
and so they clas with each other

$ rpm -qa | egrep -i isodate
python-isodate-0.5.0-1.fc20.noarch
python3-isodate-0.5.0-1.fc20.noarch

isodate is already there.

python3-rdflib-4.2.1-2.f21.src.rpm

Attached python3-rdflib-4.2.1-2.f21.src.rpm   
Seems to build
A patch0 was made
It requires python3-SPARQLWrapper-1.6.4-1.f21.noarch from Bug 1089553 to be preinstalled  (this yet needs to be added to spec file as a requires)

python-rdflib.spec (comment 6)

added a line is spec file to change the shebang python version
for i in `find . -name "*.py"` ; do sed -i -e "s/env python/env python3/g" "$i" ; done

sorry, that spec update didn't do it. python2.7 shebangs are creeping in from somewhere and I can't find it.

I think the shebang is made when creating the rpm during the _bindir 
changing the shebang to python3 after rpm installation on about 5 tools that are installed in /usr/bin is all that is needed. 

This is just to carify that the rest of all the rdflib rpm goes to the python3 sitelib, and the simple rdf programs seem to work.

Ganapathi, thank you for looking into this.

you'll need to rename python3 binaries (what goes to /usr/bin/ to something else, like python3-csv2rdf.
Otherwise, those scripts will be overwritten by their python2.7 counterparts.

any progress here?

spec file to rename console-scripts to be suffixed with 'python3-'

It was probably an atrpms-rpm-config-204-1.noarch.rpm macro python_burninversion.sh that kept overwriting the shebang which I uninstalled.

OK, I finally went ahead and used my proven packager powers to do
