That would probably be fun :) I did not write a paper for a long time and never in the field of computing.

Thank you! I feel motivated.

Ok. Is there a json guile module?
Will take a close look at the python module.

How would I go about mixing python and guile?
Export the list of package records from guile -> JSON and import in a python script?
Can I call a python-script from guile and receive input from it?

So something like:
iterate over record fields
calling a python script to fetch data from wikidata
acting on the data
feeding it to the console/web template code
fire up the webserver serving the html
