The document discusses Web 2.0 and RESTful services and how they can be used to make CICS information available to more end-users through Atom feeds. It provides definitions of Web 2.0, RESTful services, and Atom feeds. It then describes how the IBM CICS Transaction Server V3 includes a SupportPac that allows publishing CICS data like file records or queue items as Atom feeds accessed via RESTful URLs.
