hello there,
i did some work in progress to make a database for pd libraries, externals, abstractions etc.
http://iem.mhsg.ac.at/~math/pd/suche.html
i just set this up to test the core functionalities, and there is a LOT more to do (besides putting the right and complete data in, and making a decent gui) - i just publish this because i`d like to hear your ideas about it.
