[pmwiki-users] Added meta tags and schema.org microdata injection into pages

[kirpi at kirpi.it]

> <meta itemprop="image" content="{{$PageName}$:Image}" />

Thanks to Peter Bowers who suggested some more combinations.
This one above does not actually work, but a slight variation of it does!
This one is ok:
  <meta itemprop="image" content="{$PageName}$Image" />

So, in order to better feed Google, Facebook, Twitter and possibly a
lot more services/engines with many more meta data than we once used
to,  we now have a simple (though primitive) but working way, which is
based on a little "integration" on the skin template plus the setting
of a few variables.

On the other hand, a much more advanced and flexible way is given by a
recipe (to be expanded, I will try) given by Carlos on this very
thread.

Very interesting.
Thanks to all who contributed to this.
