Google has introduced a "mobile xml sitemap". Now it's possible to create your mobile sitemap with the ezpublish extension xrowmetadata.

How to use the new feature:

• Install and activate the extension
• run bin/php/ezpgenerateautoloads.php
• Create a xrowsitemap.ini.append.php in your settings/override directory
• Enabled the mobile sitemap at [Settings]
• Check the [MobileSitemapSettings]
• clear caches

<ezdir>/php runcronjobs.php -syoursiteaccess  mobilesitemap

Example:

http://www.schicksal.com is using it: http://goo.gl/6Unu6

The mobile version of schicksal.com is reachable here: http://www.schicksal.com/m/

The extension also lists all sitemaps automatically:

http://www.schicksal.com/sitemaps/index
