Design and implementation of AMGA metadata catalog system for interoperability in European middleware initiative

Abstract

AMGA (ARDA Metadata Grid Application) is a grid metadata catalog system, that is part of the gLite middleware, developed for the EGEE (Enabling Grids for E-sciencE) project. Since the end of EGEE, gLite has participated in the European Middleware Initiative (EMI) with other major middleware systems such as ARC, dCache and UNICORE. Through AMGA's three-year EMI collaboration, it has been actively developed, tested and deployed. Previously, AMGA had made progress by focusing on development for the purposes of function implementation and improvement as a metadata catalogue system. After participating in the EMI, it has designed and implemented middleware-interoperability functions according to EMI policies and strategies.
