Are there tags to specify the Google +1 story form

Question

With Facebook we have the Open Graph tags that allow webmasters to specify how the story is displayed on Facebook.

Is there something similar for the Google +1 button, that allows webmasters to specify the thumbnail image, description and title? Google+ seems to be ignoring the og-meta tags.

Answer 1

If I share a link to our webapp (restorm.com) in Google+ then the title, description and image are taken from the respective og: tags (og:title, og:description, og:image).

These tags

<title>One Shot Orchestra • Electronic • Music, Concerts & More &#8226; restorm.com</title> 
<link href="https://restorm.com/favicon.ico?116a158" rel="shortcut icon" /> 
<meta name="description" content="Listen to music of One Shot Orchestra for free and browse the Artist's news, events, videos, pictures, shop, booking &amp; press Infos, live footage &amp; much more on restorm." />

<meta property="og:title"        content="One Shot Orchestra" />
<meta property="og:url"          content="https://one-shot-orchestra.restorm.com/" />
<meta property="og:type"         content="band" />
<meta property="og:description"  content="Bangin´ Live Electro aus Bern-Kreuzberg" />
<meta property="og:site_name"    content="restorm.com" />
<meta property="fb:app_id"       content="127577323959237" />
<meta property="og:language"     content="en" />
<meta property="og:image"        content="https://assets3.restorm.com/resources/images/40/40b17a53aa9785fa89c15b06b9fcfd72_643969.jpeg?116a158" />
<meta property="og:video"        content="https://one-shot-orchestra.restorm.com/minipage/minipage.swf?applicationSettingsURL=https%3A%2F%2Fone-shot-orchestra.restorm.com%2Fminipage%2Fsettings.xml&amp;auto=true" /> 
<meta property="og:video:width"  content="300" /> 
<meta property="og:video:height" content="200" /> 
<meta property="og:video:type"   content="application/x-shockwave-flash" /> 

end up being shared like this

So the title and description are definitely taken from og:title and og:description, and not from the title and description meta tag...
