Comment 7 for bug 511657

For the particular case of CVS versions, it would best be file-specific and voided upon any change to the file (eg, inherited through revisions only where the file is unchanged). I suppose revision properties could be argued to be a near close-match, but still not quite as applicable as file-specific properties. But in other cases, who knows what metadata might be applicable? All modern filesystems (ext2+, NTFS, etc) support arbitrary metadata for files; it's only rational that Bazaar be *capable* of versioning this data (even if disabled by default).

Back to lossless conversion-- in my case I would feel it necessary to preserve the old data for as long as the new system cannot contain it losslessly. If I need to reprocess the new data someday (eg, converting generic cherry-picking metadata to something specific), so be it. Better than keeping the Subversion (or whatever) repository around and having to reconvert it and then rebase the commits since!
