Yes, the Turtle representation looks much more human friendly than the
XML variant. If we really shall directly put DOAP files into our repos,
I'd clearly prefer the Turtle variant over the XML version.

Still the Turtle representation has all this namespace boilerplate. I
really doubt we should to add yet another layer of boilerplate to our
projects. GNOME uses far too much boilerplate code already...

Also the rdf:about=""; attribute seems to be
redundant with the homepage element.

Well, and using Turtle instead of XML doesn't address those concerns:

  - DOAP replicates some information found in the AUTHORS file
  - DOAP's release tags replicate information found in ChangeLog,
    NEWS and on FTP servers
  - DOAP's repository support is limited to SVN, BK, CVS and Arch.
