The Aggregator Framework builds on the WS-ServiceGroup and WS-ResourceLifetime specifications. Those specifications should be consulted for details on the syntax of each operation.

Each Aggregator Framework is represented as a WS-ServiceGroup (specifically, an AggregatorServiceGroup).

Resources may be registered to an AggregatorServiceGroup using the AggregatorServiceGroup Add operation. Each registration will be represented as a ServiceGroupEntry resource. Resources may beregistered to an AggregatorServiceGroup using the service group add operation, which will cause an entry to be added to the service group.

The entry will include configuration parameters for the aggregator source; when the registration is made, the following will happen:

The appropriate aggregation source and sinks will be informed,
the aggregator source will begin collecting data and inserting it into the corresponding service group entry,
and the aggregator sink will begin processing the information in the service group entries.

The method of collection by source and processing by the sink is dependent on the particular instantiation of the aggregator framework (see per-source documentation for source information and per-service documentation for sink information - for example the Index Service and the Trigger Service.)

2. Operations

2.1. AggregatorServiceGroup

add: This operation is used to register a specified resource with the Aggregator Framework. In addition to the requirements made by the WS-ServiceGroup specification, the Content element of each registration must be an AggregatorContent type, with the AggregatorConfig element containing configuration information specific to each source and sink (documented in the System Administrator's Guide).

2.2. AggregatorServiceGroupEntry

setTerminationTime: This operation can be used to set the termination time of the registration, as detailed in WS-ResourceLifetime.

3. Resource properties

3.1. AggregatorServiceGroup Resource Properties

Entry: This resource property publishes details of each registered resource, including both an EPR to the resource, the Aggregator Framework configuration information, and data from the sink.
RegistrationCount: This resource property publishes registration load information (the total number of registrations since service startup and decaying averages)

4. Faults

The Aggregator Framework throws standard WS-ServiceGroup, WS-ResourceLifetime, and WS-ResourceProperties faults and does not define any new faults of its own.
