If I remember correctly, there is a bookmarks plugin that you can use 
for that purpose. Actually, I wrote a plugin for Totem that used this to 
implement the favourites functionality, you can even see a screencast of 
how it worked here (skip to 1:10 for the relevant part).

The bookmarks plugin allows you to create categories and media objects, 
so you can use APIs like grl_media_source_store and 
grl_media_source_remove to manipulate its contents. The way I used it 
was very trivial, I simply obtained GRL_METADATA_KEY_URL from the media 
I wanted to bookmark as favourite, and then used grl_media_source_store 
to push a new media element to my bookmarks plugin, passing that URL 
information (you can of course copy more metadata but I think the 
bookmarks plugin only supports a reduced subset of the metadata 
supported by grilo).

Of course all this was a long time ago and some of the APIs involved 
may have changed a bit since then. Anyway, here is the source code of 
that plugin for your reference, I think it should e easy to replicate 
using current APIS:

Maybe some other Grilo dev can give more up-to-date references :)

Hope this helps.
