area-tag

An  area-tag  is a special kind of tag that tags a specific area or region of a post which can be used to tag a photo post with person-tags at specific locations/areas where each person appears in the photo.

Why
Use area tags to indicate who is who or what is what in a photo.

How to
TBD. See

Brainstorming
All examples are contextually inside an h-entry.

area tag with note
Area tag with a note: 

person tag as area tag
person-tag as an area-tag: 

wondered if you could tag people in photos by linking to their profiles using HTML imagemaps (!) and marking up the imagemap links with microformats. That might look something like:

However, because the HTML syntax of imagemaps sits outside the actual image tag, it may be worth adding a microformat to the map itself.

area tag reply
Area tags can be placed inside a tag-reply to tag some other post with area-specific tags, including person-tagging people at specific points/areas in someone else's photo post.

The reply-context for an area tag reply to a photo post for example should include the entire photo that is being area-tagged, so that the area element can overlay the portion of the photo. And a person area tag reply could actually display a name/link of the person tag, on top of the person in the photo, and even do hover effects triggered by point proximity or a rectangle overlaid on the person in the photo.

Potential Bridgy Publish feature request:

Once someone has implemented publishing an area tag reply on their own site, in particular, a person area tag reply to both an original post and e.g. a Facebook or Flickr POSSE copy of it (or at least a person photo tag of a silo photo post), it would be beneficial for Bridgy Publish to support POSSEing that tagging to the silo POSSE copy:
 * Bridgy Publish to POSSE a copy of your "photo tag reply post" to a silo that has the photo (perhaps POSSE copy thereof), where Bridgy could do the photo-tagging for you on the silo as your reply post specifies to do.
