SWPDM is a tool mainly designed to support the development of SolidWorks projects. SWPDM can manage any file type you stick in it, but it is not designed to be a PDM system for continued development in different CAD packages.
Since SWPDM runs in Windows Explorer you could open CATIA files from the vault and save them back into the vault. You would have to do all the check in/out from the Windows Explorer interface. There is no CATIA add-in like there is for DraftSight or MS Office. You might be able to save some PDM metadata, but it probably would not write anything to the CATIA file. If you work with Pro/E (Creo) files you might be able to get a copy of the Pro/E connector, but it is for legacy use only.
I don't have any supporting documents for you sorry.
