Integrating TweetOut with XPression Studio involves four (4) configuration steps:

  1. In TweetOut, use BLADE to generate an RSS Query String URL for a Twitter or Facebook playlist or topic.  
  2. In the DataLinq Server, configure a DataLinq source for that RSS feed from TweetOut.
  3. Using XPression DataLinq Manager, connect XPression to the XPression DataLinq Server to pull data from the established source(s).
  4. In XPression, tag text or graphic objects to display content updates automatically.
 
Note: This section details the specific integration required between XPression Studio, the XPression DataLinq Server, and BL TweetOut. See the XPression Studio Online Help system for complete details on working with XPression Studio and XPression DataLinq Server.
