Well, that is the only word of french I understand, perhaps a couple
of expressions too, but that is not the point.

Oh, It makes me sad that you gave up on trying to give a programatic
answer to your own needs.

For me it all started like this.

But not all is lost, I've made the recipe.

The idea is not deep/complete/"close to the core" as the idea proposed
by V. Krishn, but it works and it is simple, so you perhaps can give
programming one more try. :-)

But you'll have to write the page in the cookbook.
Do we have a deal?!

Anyway, here is the code:

---------8x---------

<?php

Markup('fbgpmeta',
       'directives',
       '/\\(:fbgpmeta\\s(.*?):\\)/ei',
       "FbGpMeta(PSS('$1'))");

function FbGpMeta($a){
global $HTMLHeaderFmt;

 $o = ParseArgs($a);

 if($o['image']){
   $o['image'] = PUE($o['image']);
   $im = "\n<meta property=\"og:image\" content=\"".$o['image']."\"/>\n"
         ."<meta itemprop=\"image\" content=\"".$o['image']."\" />\n";
 }

 if($o['title']){
   $tm = "\n<meta itemprop=\"name\" content=\"".$o['title']."\" />\n"
         ."<meta property=\"og:title\" content=\"".$o['title']."\"/>\n";
 }

 if($o['description']){
   $dm = "\n<meta itemprop=\"description\"
content=\"".$o['description']."\" />\n"
         ."<meta property=\"og:description\"
content=\"".$o['description']."\"/>\n";
 }

 $HTMLHeaderFmt['fbgpmeta'] = $im.$tm.$dm;
}

---------8x---------

I did it really fast, but there is one thing I'm in doubt of ...

Do I have to PUE description and title?(if others can answer, TIA)
