Thanks for the info (though I can't actually find the relevant file in
that repo atm).

Anyway I was aware of their original work on pd calculators in code
since we were working on it with them -- the public domain works
project here has now been going off and on for 4 years+ :)

>From what I remember of the code it was, like ours at the time, pretty
rudimentary and this latest coding effort -- which is a complete
upgrade/rewrite of the original -- represents a significant advance (+
it is properly tied in to the underlying DB/domain model which means
we can actually calculate PD status for a very large number of works!)
