Overview

This document is for system administrators who want to configure and maintain the WS Index Service (MDS3) for generating, aggregating, indexing, and querying Grid services and service data.

The GT3.2 version of the Index Service supports multithreaded, recurring execution of providers via Java TimerTasks and asynchronous notification of changed service data to listening OGSA Notification Sinks.  It is also possible to create server-side subscriptions to other OGSA service data, where the notification messages of these server-side subscriptions get cached in the local service data container – this is known as Service Data Aggregation.
