The Reporting Services Atom rendering extension generates an Atom service document that lists the data feeds available from a report. The document lists at least one data feed for each data region in the report. Depending on the type of data region and the data that the data region displays, Reporting Services might generate multiple data feeds from a data region. Atom service document contains a unique identifier for each the data feed and you use the identifier in a URL to view the content of the data feed. For more information, see Generating Data Feeds from Reports (Report Builder and SSRS).
