 From a concept part we could work together here - what makes sense, 
what would be the useful information for the user etc. I started a list 
for resource types recently in my UI documentation - for me there is 
also the question of clustering types (not technical types, but logical 
groups for the user). This is open for discussion...

      Resources can be:

          o

            Files (like PDF, OpenOfficeWriter Documents, Images, html
            sites ...)

          o

            Media (music files mp3, movies flv, games, podcast?)

          o

            Contacs (Peoples name, adress, email adress, chat accounts,
            phone number, etc)

          o

            aplications (any aplications on the device, like Office,
            graphics programs, email clients, media player etc)

          o

            bookmarks? Urls

          o

            locations (adress, name, tag)

          o

            events? = calendar entries

          o

            tasks?
