Many folks like schools, employers, etc still publish calendars in PDF format.

They spend more time on branding and visual formatting, than trying to create the same in formats that we can import into our calendar apps and actually use it practically.

I wonder if there is a two step process we can follow that will more robustly generalize ...

1. Read any document and convert into into a simple table that tries to tabulate: date, time (+timezone), venue, url, notes, recurrence

2. Read a table that roughly has the above structure and use that to create google/ical/ics files or links

We may be able to fine tune a model or agent separately to do each step very well.
