This plugin allows you to add/edit/delete metadata key/value pairs for a given page. You must be logged in as the administrator to do this. The page's metadata contains things like the page hit count, last edit time and so on.

Editing the metadata for the homepage would look like this:

Existing page-level metadata for HomePage:
stats:
stats[max_online_num] => 2
stats[max_online_time] => 1087302709
date => 1012170535
hits => 11418
Requires WikiAdmin privileges to edit.

With no arguments the plugin defaults to the current page:

Existing page-level metadata for EditMetaDataPlugin:
date => 1073237029

Requires WikiAdmin privileges to edit.
