A second stage data feed is constructed in a neutral format from source data in a non-syndication format. A content transformation agent is customized for a first source data repository, and the first stage data feed is constructed in the neutral format by dynamically selecting and transforming within the first source data repository selected data primitives of the source data into the first stage data feed in the neutral format. The first stage data feed includes the selected data primitives stored originally in the first source data repository. The first stage data feed is sent to an aggregation agent that generates a second stage data feed as a union of selected data primitives from the first stage data feed. The second stage data feed is generated by detecting relationships among the selected data primitives. The second stage data feed includes related selected data primitives from the first stage data feed.
