This is cool!

Some small things that should be easy to do, but might be usefull:
1) Might be nice, if more resources would use title Attribute for usefull
things. Eg. DirectoryResource could give a title, if available, instead of
boring 'Directory of Bla'. I think  it would be nice to have that, not sure
if anybody else supports it. :-?

2). Default HEAD implementation does GET and then cutoff the entity body.
It might be more efficient if at least the major resource like FileResource
and DirectoryResource override that to do faster version of HEAD. That
might give a slightly better edge.

3) extended() method default handler,  gives and error of unimplemented
UNLINK method. Just cut and paste problem, I guess. :-}.

4) Documentation seems to be inconsistant. Somebody should really look into
it. (mostly URL references and some CLASSPATHs, but some things like "The
only real way to reindex the whole system is to delete all .jigidx files
and let Jigsaw to reindex everything when it needs it." - here goes all the
admin functions, they are not recreatable. Remember somebody was saying
that bootstraping Jigsaw was a tricky bit :-} ).

5) URL to <http://www.w3.org/members/WWW/Jigsaw> should be either removed
from sample welcome Jigsaw page or open for public. It gives 403 Forbidden
by Rule everytime, and Boy I would like to know what is supposed to be
behind those closed doors. :-}

Good luck,
     Alex.

Ps. Just a note: Jigsaw Alpha 1 is cleaner then some products' gold
versions....... :-}
