GT 4.1.3 WS MDS Aggregator Framework: Developer's Guide

Introduction

The Aggregator Framework allows pluggable data sources and sinks to be written and connected together. Generally a source collects data from or about a particular grid resource, and passes it to a sink which does something interesting with it.

The aggregator sinks supplied with the toolkit implement the Index Service and Trigger Service. The aggregator sources supplied with the toolkit collect information using resource property queries, subscription/notification, and execution of external programs.

This document describes the programmatic interfaces to the Aggregator Framework. See also general Globus Toolkit coding guidelines and GT 4.1.3 best practices.
