Answer 1

new version of XML Sitemap module helped me.

The XML sitemap module creates a sitemap that conforms to the sitemaps.org specification. This helps search engines to more intelligently crawl a website and keep their results up to date. The sitemap created by the module can be automatically submitted to Ask, Google, Bing (formerly Windows Live Search), and Yahoo! search engines. The module also comes with several submodules that can add sitemap links for content, menu items, taxonomy terms, and user profiles.

try this in your module

$tags =array();
//add stuff to tags    
 foreach($tags['og'] as $key => $value)
                 {
                  $meta = array(
                    '#tag' => 'meta',
                    '#attributes' => array(
                      'property' => 'og:' . $key,
                      'content' => $value
                    )
                  );
                  drupal_add_html_head($meta, 'og_meta' . $key);
                 }
