Hi,

you don't need baloo for setting or getting the attributes from a file. The
important part is, that the attributes are stored in a namespace as defined
here: http://www.freedesktop.org/wiki/CommonExtendedAttributes/

baloo uses the following namespaces for attributes:
 - user.xdg.comment
 - user.xdg.tags => tags are separated with , 
 - user.baloo.ratig => rating range is from 0 to 10 (9 is displayed as 4.5
Stars in dolphin)

In "the near future" baloo will detect changes on this attributes on its own,
see Bug 337602 for more information.

I think the real cool part is, that every application which uses the
freedesktop defined namespaces will be able to interpret those attributes and
is not depened to another software or library.

I don't know how to set the attributes with C/C++ but I have found these:
