GT 4.2.1: WS MDS Aggregator Framework


The Aggregator Framework is the software framework on which WS MDS services (currently, the Index, Trigger and Archive Services) are built. The Aggregator Framework collects data from an aggregator source and sends that data to an aggregator sink for processing. Aggregator sources distributed with the Globus Toolkit include modules that query service data, acquire data through subscription/notification, and execute programs to generate data. Aggregator sinks include modules that implement the Index, Trigger and Archive Services interfaces.
