This topic introduces the feed definitions file, which is available for editing in the Services Config view > Files tab. One of the files available for editing in the Services Config view > Files tab is feed-definitions.xml, the feed definitions file.
You can define feeds in the feed-definitions.xml file. The Decoder uses an XML schema to define feed messages when it creates a binary .feed file from the feeds defined here.
For details on the feed definition language, refer to Custom Feed Definition File Structure
