Welcome to GoldenOrb GoldenOrb is a cloud-based open source project for massive-scale graph analysis, built upon best-of-breed software from the Apache Hadoop (http://hadoop.apache.org) project modeled after GoogleÕs Pregel (http://portal.acm.org/citation.cfm?id=1807184) architecture. Our goal is to foster solutions to complex data problems, remove limits to innovation and contribute to the emerging ecosystem that spans all aspects of big data analysis.
