There is a quite significant technical problem with this idea.

PDF files are themselves essentially software. When the PDF program
is executed, the result is a page that was originally printed on
paper by a printer, but nowadays can also be displayed on a computer
screen.

You can think of PDF as a programming language for creating graphics,
ie. visual information. Symbols and footprints can however not be
created reliably and correctly from a graphics source document such
as PDF, because symbols and footprints consist of highly structured
information, which happen to also have a graphical representation.

It is possible to reliably and correctly create a graphical
representation from structured information. It is not possible
to do the reverse reliably and correctly.

So PDF is not a suitable source format for what you want to do.
It is however the only commonly available description at the moment.

What you want to accomplish essentially requires strong committment
by component vendors to contribute information. There are efforts
heading in this direction already.
