nautilus smart folders xml mockup

[rakudave <rakudave gmx net>]

hi there

yes, *thou shalt not copy everything from apple*, but the "smart 
folders" are quite hany.
why not intergrating this feature into nautilus as well? (without tracker!)

my idea is to use the metafiles, where additional infos such as notes 
and emblems are stored.

today:
<directory>
<file name="Radiant_Chess_1600x1200.jpg" timestamp="1214979912"/>
</directory>


idea:
<directory>
<file name="Radiant_Chess_1600x1200.jpg" timestamp="1214979912" 
tags="wallpaper, dark, chess"/>
<smartfolder tags="dark" date="-1209600"/>
</directory>

the smart folder would display all files within the current directory 
that are no older than 2 weeks and are tagged with "dark"
(2 weeks are represented as seconds in this mockup)


what do you think?
regards
