About

• Purpose: an atom with a little bit of content and possibly an owner
  • ID_Owner: ID of user who owns this atom.
    • Some post types will not have owners, but this needs to be here so it can be part of the unique key. We don't want to prevent different users from using the same Summary.
• Fields:
  • URI: I haven't yet decided if this really belongs here or how to formally define it, but it could be used for either:
    • a page on the site which is set aside for more information about the given post
    • the post's official URI on the site
• History:
  • 2013-03-12 Created, but not yet in use.
  • 2013-03-15 Most fields moved from post to atom; added ID_Owner.
