About

• Purpose: an atom with a little bit of content and possibly an owner
• Fields:
  • ID_Owner: ID of user who owns this post (NULL means ownership is not relevant)
  • Summary: subject, title, or one-line description
    • Some post types will not have owners, but it's a common enough thing that I thought it should go in at a low level.
• History:
  • 2013-03-12 Created, but not yet in use.
  • 2013-03-15 Most fields moved from post to atom; added ID_Owner.
  • 2013-06-28
    • Decided to remove URI until there's a clear purpose and need for it.
    • Removed owner/summary uniqueness requirement; can't see need for this either (e.g. multiple posts might be called "status report", for example).
    • Added Body field to make this independent of the containing CMS.
  • 2013-07-21 ID_Owner needs to be DEFAULT NULL (not NOT NULL) if it's going to be optional. Duh.

SQL

<mysql> CREATE TABLE `post` (

  `ID_Atom`     INT              NOT NULL COMMENT "ID of atom this post is using",
  `ID_Owner`    INT          DEFAULT NULL COMMENT "optional: ID of user who owns this post",
  `Summary`     VARCHAR(255)     NOT NULL COMMENT "short description, for listings",
  `Body`        TEXT         DEFAULT NULL COMMENT "body of post (optional)",
  PRIMARY KEY(`ID_Atom`)
)
ENGINE = MYISAM;

</mysql>

Obsolete

• 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

<mysql> `URI` VARCHAR(255) DEFAULT NULL COMMENT "optional site-relative URI for more information",</mysql>
