Yes, that's what I wanted to discuss. Thinking about it, this discussion is absolutely not new. In fact, this is the typical filesystem/metadata discussion, which appeared on all OS'es and desktop environments again and again, and which has lead to a lot of nice concepts and extended attributes/metadata-supporting filesystems (and a lot of vaporware a la WinFS or Reisers' vision). I think freedesktop.org has lead to some standardization in this respect, and one might find libraries (I am thinking of what KDE4 etc. use) that allow dealing with such metadata without knowing where it is stored. That may allow taking advantage of filesystems that support attaching such data directly to files (best option) and provide a transparent fallback solution for those that don't. Actually, I was thinking about Nepomuk, but that does not seem to use extended attributes at all right now. :-/ http://nepomuk.semanticdesktop.org/ Nevertheless, using such libraries could be a 3rd option, but I don't want to imply at all that I believe this to be the best option. > Cover images for readonly media would be stored in the overlay > directory, which beacon does support directly. Yes, that would obviously be the appropriate solution. I'll eventually have a look at that, too (for now, I won't care about cover images). -- Ciao, / / .o. /--/ ..o / / ANS ooo
