Create a YooTheme WidgetKit content provider for Joomla! native custom fields

We're working with the latest YooTheme WidgetKit version and need to stick to Joomla! Articles as our only Widgetkit content provider (so we want to avoid using any third party CCK like ZOO or K2 etc.). Basically, the feature of including Joomla! articles as a content provider is already included in WidgetKit. But what is missing in the native Joomla! content provider, is the possibility to access Joomla! native CUSTOM FIELDS. There is alreday a documentation from YooTheme, which explains how to build a "custom content provider": [login to view URL] [login to view URL] Your mission - should you choose to accept it ;-) - would be, building a content provider for uns, that meets the following requirements: 1. the free mapping of custom fields to WidgetKit fields (like it is possible with custom widgets). PRIORITY: HIGH 2. the dynamic integration of joomla custom fields (if a new one is created, it can be selected) PRIORITY: LOW Fields we need: Vorname (text) Name (text) Funktion (text) Adresse (text) PLZ (number with 4 digits or text) Ort (text) Telefon (number formated like XXX XXX XX XX or text) E-Mail (url in format MAILTO (must be clickable and "encrypted"))
