Extended correlation methods in a content transformation engine

A method for communicating data, comprising:

• customizing a first content transformation agent for a first source data repository that stores first source data;
• providing, to the first source data repository, the first content transformation agent for the first source data repository,
• customizing a second content transformation agent for a second source data repository that stores second source data;
• providing, to the second source data repository, the second content transformation agent for the second source data repository,
• in accordance with the customization of the first content transformation agent, constructing a first first-stage data feed in a neutral format by dynamically selecting and transforming, within the first source data repository, selected first source data into the first first-stage data feed in the neutral format, the first first-stage data feed comprising the selected first source data stored originally in the first source data repository,
• in accordance with the customization of the second content transformation agent, constructing a second first-stage data feed in the neutral format by dynamically selecting and transforming, within the second source data repository, selected second source data into the second first-stage data feed in the neutral format, the second first-stage data feed comprising the selected second source data stored originally in the second source data repository;
• sending the first first-stage data feed and the second first-stage data feed to an aggregation agent;
• and
• generating, by the aggregation agent and based on criteria specified by a user, a second stage data feed as a composite of selected first source data from the first first-stage data feed and selected second source data from the second first-stage data feed.
