Error simple rdfa #27

Closed RichDijk closed 5 years ago

RichDijk commented 5 years ago

I just want to start to have a running configuration of pyrdfa. But running Python 3.7 and rdfa3 ==3.5 gives the following error.

from pyRdfa import pyRdfa
import rdflib
print(pyRdfa().rdf_from_source('pyrdfa.xml'))

Input file pyrdfa.xml

What is going wrong?

@RichDijk, this was a leftover from the old times, and is not a problem in python2. The file built-in is not available in Python3 anymore, open should be used instead.

I have made an update of the code in this repository as well as on PyPI. I think this should work now.

Thanks for reporting!

Using pyrdfa3-3.5.1 works fine now. Thank you.
