Need:
- Additional type: Entity reference to a taxonomy vocabulary including (at least) the schema.org subtypes.
- License: Taxonomy vocabulary with at least the Creative Commons licences, maybe GNU FDL, and other usual suspects.
- Image: Jacob has it as an image field. It should be an entity reference to a Media image_object. (I have to go through other content types and do the same.)
- Related link: Damn, I think url fields should be entity references to a content item we have (with a URL field). Unless we can map two Drupal fields to the same schema.org property. Actually, I think maybe we can.
