ESGIA: Extensible service based grid information aggregator

Interoperable Grid monitoring has been a hot topic since many years (Wolski et al 1999, Michael and Philip 2002). Standardization efforts have been made by the Open Grid Forum with respect to monitoring architecture (Zanikolas et al 2005) and data schema. Grid middleware efforts towards interoperability include GRIP, which resulted in an interoperability layer between UNICORE and GT2, OSG, LCG and the ongoing OMII Europe project.
