In this paper, we introduce the enhanced Kepler framework, an evolution of the original Kepler framework that implements an OAI-PMH-compliant data provider for the individual. The enhanced Kepler framework is influenced by Fasttrack, a peer-to-peer network. In particular, we introduce the concept of buddy nodes and SuperNodes to improve scalability. We also propose enhancements of OAI-PMH, the harvesting protocol used in the existing framework, to support the "push" and a hybrid "push/pull" model for metadata harvesting. The enhanced Kepler framework provides the following benefits: improved availability of content published by individuals, rapid discovery of content as soon as it is published, and works with firewall and network address translation proxy.
