saving out to IFC format will make the library part available with all the embedded data to any other program that can import IFC files. It is an open standard and negates having to create individual files or translators for each set of programs.
That said, the success of importing and exporting IFC files varies per program. Graphisoft has some of the best translators. When developing the library part, see if you can find users of other applications like archicad to test the IFC, or other format(s) that you are considering.
