Possible class names

General class name considerations

• “last-modified”
  • + “paveing the cowpaths” (“Last-Modified” used by HTTP 1.0 and 1.1)
  • - HTTP’s “Last-Modified” Header has a slightly different meaning. (Last modification date of the resource, not the last modification date of the resource’s logical content)

• “last-updated”
  • + New name for a “new” semantic.

Different class name for page specific and item specific dates?

For example “page-last-modified” is used to indicate the last modification date of a page and “last-modfied” for the last modfication date of a specific item*.

• Pro
  • Easy parsing
• Contra
  • ...

* This specific item is marked-up with a microformat, e.g: a microformat to describe blog posts may use “last-modified” to indicate when a blog post was last modified.

Possible date formats

Every date format which can be used with datetime-design-pattern can be used with “last-modified”

Theoretical example

This page was last modified 13:26 UTC, 15 Aug 2005.

could be written as

This page was last modified 
<abbr class="some-class-name" title="2005-08-15T13:26Z">13:26 UTC, 15 Aug 2005</abbr>.
