Open Graph protocol should be integrated

by balexandre   Last Updated September 11, 2019 20:24 PM

In order for a better experience when sharing a link over Facebook (and not only there) it would be nice to have the Open Graph protocol in a page.

For example for

<meta property="og:title" content="Bicycles - Stack Exchange"/>
<meta property="og:type" content="forum"/>
<meta property="og:url" content=""/>
<meta property="og:image" content=""/>
<meta property="og:site_name" content="Bicycles - Stack Exchange"/>
<meta property="og:description"
      content="Q&A for people who build and repair bicycles, 
               people who train cycling, or commute on bicycles"/>

My question would be... to add what? Most of that data is already available via regular html, and it doesn't do too badly:


adding an image... well, that's interesting because we do do that for apple-touch etc:

<link rel="apple-touch-icon"

so it wouldn't seem reasonable to advertise the logo that we share on stackauth:


(or possibly the first image in the markdown? defaulting to site logo?)

but the rest seems a bit redundant? Of course, there is a reasonable number of iOS users, where-as facebook links would be much rarer. I wonder if there is any way to detect if the caller might be interested in the open-graph data, i.e. add it when it might help (so: for facebook's servers calling us)

Edit: and here's bicycles:

Which could potentially have additionally the logo:

I don’t know when it happened, but Stack Exchange sites now use the Open Graph vocabulary.

Previously specified in HTML5 meta tags, which was invalid, but at some time after 2014-02 via RDFa.

This very question, for example, uses RDFa in the head (I have removed the unrelated HTML5 and Microdata attributes):

<meta property="og:type" content="website" />
<meta property="og:image" content="/content/stackexchangemeta/img/[email protected]?v=c34d758b103d" />
<meta property="og:title" content="Open Graph protocol should be integrated" />
<meta property="og:description" content="In order for a better experience when sharing a link over Facebook (and not only there) it would be nice to have the open graph protocol in a page for example for" />
<meta property="og:url" content=""/>

As they don’t define the prefix og, the RDFa Core Initial Context gets used where og has the URI, so it’s the Open Graph protocol.
