## Detailed Description

The DataOnDemandSvc listens to incidents typically triggered by the data service of the configurable name "IncidentName".

In the job options handlers can be declared, which allow to configure this service. Such handlers are either:

- Node handlers, if objects other than the default object type have to be instantiated. DataOnDemandSvc.Nodes = { "DATA='/Event/Rec' TYPE='DataObject'", "DATA='/Event/Rec/Muon' TYPE='DataObject'" };

- Leaf handlers (Algorithms), which get instantiated and executed on demand. DataOnDemandSvc.Algorithms = { "DATA='/Event/Rec/Muon/Digits' TYPE='MuonDigitAlg/MyMuonDigits'" }; If the algorithm name is omitted the class name will be the instance name.

The handlers only get called if the exact path mathes. In the event already the partial path to any handler is missing a leaf handler may be triggered, which includes the partal pathes ( DataOnDemandSvc.UsePreceedingPath = true )

2006-10-15: New options (using map-like semantics:)

        DataOnDemandSvc.AlgMap  +=
       { "Phys/StdLoosePions/Particles" : "PreLoadParticles/StdLoosePions" ,
         "Phys/StdLoosePions/Vertioces" : "PreLoadParticles/StdLoosePions" } ;

        DataOnDemandSvc.NodeMap +=
       { "Phys" : "DataObject" ,
         "MC"   : "DataObject" } ;

New treatment of preceeding paths. for each registered leaf or node the all parent nodes are added into the node-map with default directory type 'DataObject'

The major properties are equipped with handlers (more or less mandatory for interactive work in python)

From now the default prefix ( "/Event/" ) coudl be omitted from any data-item. It will be added automatically.
