Metadata management and grid computing within the eMinerals project

Abstract

We report a pragmatic approach for metadata management developed by the eMinerals project and which enables non-intrusive automatic metadata harvesting from grid- enabled simulation calculations. The framework, called the RCommand framework, gives users a set of unix line commands and a web interface to the metadata database.Harvesting of metadata relies on the use of XML for output data file representation, and new developments of the RMCS grid job submission tool incorporating the AgentX library. We report the use of the Rgem tool to use metadata as a direct interface to data to enable collation of data obtained from parameter-sweep grid studies.
