Support of Open Graph protocol¶

Meta-information added to a page in conform to open graph protocol allows you to integrate a content of a page to a social graph. In other words, by clicking a “Share” button for the page it will be correctly displayed for social networks like Facebook.

To generate a social meta-information for a page add a method call ogmeta inside a head html tag:

<head>
  $!{ogmeta()}
  ...
</head>

Calling ogmeta with the more specific parameters:

<head>
  $!{ogmeta(["title":"Test page", "image":"some_image_ref", ...])}
  ...
</head>

As a result, the page will contain the html markup like this:

<head>
  <meta property="og:site_name" content="site.com"/>
  <meta property="og:image" content="http://site.com/rs/media/fileid/323"/>
  <meta property="og:title" content="Test page"/>
  <meta property="og:locale" content="en"/>
  <meta property="og:type" content="article"/>
  <meta property="og:url" content="http://site.com/news/123"/>
  ...
</head>

The default ogmeta fields:

og:url - A page URL. Cannot be overridden.
og:site_name - A site virtual host name. Cannot be overridden.
og:locale - A locale of http request. Cannot be overridden.
og:title - A page title, the default is page.hname. It may be overridden by title argument passed to ogmeta method.
og:type - Page type, the default is article. It may be overridden by type argument passed to ogmeta method.
og:image - An image banner associated with page. It will be used if the image argument is specified. The value of an argument may be a name of image <am_image> assembly attribute or path to an image file in media repository.
