Just realized that I KISSed examples too much and didn't notice a mistake.  
Need to sleep more :( and stop talking to myself...

Anyway, resource has to have a prefix: or has to be included in <> brackets.

Also, I changed field naming to xesam:Audio.composer. This seems to be better 
due to Jamie's wish to explicitly link DC and other external ontologies. I 
don't object this either.

These two examples now look like this:

=========    #1      ======================
=====================================
@prefix DC:             <http://freedesktop.org/standards/DC#>
@prefix xesam:  <http://freedesktop.org/standards/xesam#>
@prefix :                       <http://freedesktop.org/standards/xesam_base#>

xesam:Audio.Composer
        a                       :field;
        :of_type                :string;
        :has_parent     DC:Creator;
        :name           "Composer"@EN;
        :name           "Композитор"@RU;
        :description    "Audio composer".
=====================================

=========     #2    =======================
You can map rdf:Property to something other like file:Property
not sure which is better. Any ideas for the prefix since xesam: is now used?
I still strongly advise to use #2 an not #1.
=====================================
@prefix rdf:            <http://www.w3.org/1999/02/22-rdf-syntax-ns#>.
@prefix DC:             <http://freedesktop.org/standards/DC#>
@prefix type:           <http://freedesktop.org/standards/xesam_base#>
@prefix xesam:  <http://freedesktop.org/standards/xesam#>
@prefix :                       <http://www.w3.org/2000/01/rdf-schema#>

xesam:Audio.Composer
        a                               rdf:Property;
        :range                  type:string;
        :subPropertyOf          DC:Creator;
        :label                  "Composer"@EN;
        :label                  "Композитор"@RU;
        :comment                "Audio composer".
=====================================

Will re-check this when I wake up once more :)

Sorry for confusion.
