Here's how it is implemented in templates for GavickPro Joomla-articles:
// OpenGraph support
$template_config = new JConfig();
$uri = JURI::getInstance();
$article_attribs = json_decode($this->item->attribs, true);
$og_title = $this->escape($this->item->title);
$og_type = 'article';
$og_url = $cur_url;
$og_image = '';
$og_site_name = $template_config->sitename;
$og_desc = '';
if(isset($article_attribs)) {
$og_title = ($article_attribs == '') ? $this->escape($this->item->title) : $this->escape($article_attribs);
$og_type = $this->escape($article_attribs);
$og_url = $cur_url;
$og_image = ($article_attribs == '') ? '' : $uri->root() . $article_attribs;
$og_site_name = ($article_attribs == '') ? $template_config->sitename : $this->escape($article_attribs);
$og_desc = $this->escape($article_attribs);
}
$doc = JFactory::getDocument();
$doc->setMetaData( 'og:title', $og_title );
$doc->setMetaData( 'og:type', $og_type );
$doc->setMetaData( 'og:url', $og_url );
$doc->setMetaData( 'og:image', $og_image );
$doc->setMetaData( 'og:site_name', $og_site_name );
$doc->setMetaData( 'og:description', $og_desc );
