Re: [Tracker] Upcomming API review

["Samuel Cormier-Iijima" <sciyoshi gmail com>]

I'm not sure something like this would be a great idea, unless there
were another method of storing the bookmarks. Users often have
preferences about more than just the bookmarks themselves (order,
expanded or not). Also, this would lead to some strange problems if
(for example) the user happened to download a file with that metadata
and tracker indexed it, or if another program used the same format or
something. It seems to me that the 'Right Thing' would be more to make
Epiphany store its bookmarks in something like XML, and have Tracker
be able to extract metadata directly from the bookmark file? Possibly
not (I haven't really looked at how Epiphany stores its bookmarks, so
I may be pulling **** out of my *** :-) A good frontend to Tracker
(which I'm thinking about writing) would have an option to turn on or
off bookmark indexing, which might also be better than having Epiphany
trying to autodetect Tracker.

Anyways, just my two cents. :-)

Cheers,
Samuel
