Interesting idea, particularly for autogenerated metadata. Some metadata, like thumbnails and icons might as well be ordinary files though. (Like some icon and want to use it as background bitmap? Just copy it, because it is a plain file. Or want to use it as clipart - fine, the word processor supports bitmap files. . .) This is a case where something is "metadata" only because it is used as such, not because it has to be. File-as-dir is an interesting concept for such cases, because it is convenient to group the "metadata" with the file, have it move with the file and so on. But still have this metadata accessible as a file because it isn't all that special. Helge Hafting
