eZ Publish does not allow editing of meta data (meta keywords and meta description) for individual objects, that's why I wrote this extension.
For installation, simply enable the extension in admin interface. Also, make sure files in your eZ Publish autoload folder is writable. After activation you should see a new section called "Meta Data" when editing an object.
Extension works with eZ Publish 4
