In my response I only considered raw, not standard formats.
What you mean by "not integrated" is, I assume, the XMP metadata (eg rating or label) and perhaps the the large preview.
It is possible to get the XMP data into each of those cataloguing programs in their current versions. I am already doing this with DNG files and Portfolio 7 (it also works with Nikon and Fuji raws). The cataloguing programs also show the ACR-corrected/cropped thumbnails, though currently they don't extract DNGs' large previews.
To get the XMP data, you script the export of data from Bridge (
see here) and then import it into the catalogue - you don't touch the raw/DNG raw image settings. The coding isn't tough and any of the fields you see in Bridge's metadata panel can be exported, the camera raw settings too, if you want. OK, it's not a live link but the cataloguing vendors are working on this area and you'll see mapping to XMP within months.
Looking at it practically, try searching with Bridge on a keyword with a folder structure containing 10000 records in maybe 100 folders. Then repeat in a database. I like Bridge, but it's a file system browser and doesn't pretend to have the virtues of a database.
