Facebook open graph- share a poem instead of an article

My website shares poems, stories and articles. This is an example of an open graph of a poem.

      }
   ],
   "is_scraped": true,
   "site_name": "MyPen.net",
   "title": "My Complexity",
   "type": "article",

   "data": {
      "section": "Poems"
   }
}

The problem is, that when a user shares a poem, facebook tells it's an article. I've read in other places that i should set og:type to article, but it's doesnt seems right:

Is there any way to set the open graph to say "Eran Shmuel shared a poem on mypen"?

Or do I have to change og:type to "website" for poems and stories?
