Hi,
probably not the right mailing list for this mail but not sure where to ask :)
Based on DBpedia dumps I created a script that identifies usage of undefined templates in Wikipedia, most times due to spelling mistakes.

I was wondering if it makes sense to extend this script and - provide suggestions based in string similarity metrics - extend this in infobox properties and report properties that are not defined in the template definitions (And also provide suggestions from existing properties)
I did create a one-time dump for all of the above for the Greek Wikipedia 4-5 years ago but not sure if Wikipedia maintains this automatically now
note that this is based on the Oct dump and might be a little out of date
Cheers, Dimitris
