Create RSS Feed from my MySQL database for OVI App Wizard

I want to publish my content with the OVI App Wizard, the mobile application by Nokia. To be able to do that I need to create two RSS feeds out of my MySQL database. One - with content restriction - for the free app, the other one for the paid app. - Create two RSS feeds from my database according to the functional logic provided or/and by an JSON API. - Usability: Adapt the available content to make sure the content is displayed in the best possible way in terms of navigation, display and usability. - Take care of security issues with the script. I need somebody who knows how to get the best possible results with the existing OVI App Wizard respectivly with mobile applications. Thanks
