Atom is a lightweight syndication technology, based on XML, that allows data to be published on, and retrieved from, the Web. Atom does not currently provide reliable data distribution or consistent data replication. In this paper we describe a novel Reliable Data Distribution and Consistent Data Replication infrastructure for Atom. Reliable Data Distribution ensures that the intended consumers have obtained the data that the publisher published and that the publisher can garbage collect the data. Consistent Data Replication provides high availability and fast local access to the data at the consumers. We also describe a potential application of, and present performance results for, the Reliable Data Distribution and Consistent Data Replication infrastructure that we developed.
