Abstract

For Draft -09

Status

Proposed

Rationale

Having a way of indicating the date the entry was last modified is a good optimization to avoid having to HEAD each individual member URI to get the Last-Modified header.

Proposal

8.# The "atom:modified" Element

The "atom:modified" element is a Date construct as defined by [RFC4287] whose
value indicates the most recent instant in time when an entry was modified in 
any way.  Atom entry elements MUST contain one "atom:modified" element.

  atomModified = element atom:modified ( atomDateConstruct )

Publishers MUST change the value of this element every time a collection member 
resource has been updated, or an associated Media Resource has been modified.


Impacts

Adds a new mandatory element to every element in a collection feed.

Notes

Example:

  <entry xmlns="http://www.w3.org/2005/Atom" xmlns:app="...">
    <id>urn:lsid:example.org:entries:1</id>
    <updated>2006-07-11T12:12:12Z</updated>
    <modified>2006-07-11T12:13:13Z<modified>
    ...
  </entry>
