This session could include:

• CaloHive in athenaMT
• Extend ID experience to migrate first Muon algo(s)
• Implementation of Arrays of Handles / optional Handles
• Can we manage without UpdateHandle? How to deal with collections that are not relevant to scheduling
• Creation of IDC in views

Notes:

• Array of Handles: Agreed to add these (Charles)
• UpdateHandles: Alternatives found for use cases discussed
  • Update common pattern in muons, simplest solution is copy.
  • PixelAmbiguitiesMap (axample showed by Adam) not needed.
• Trigger use-case for offline data preparation: Add RegionSelectorSvc to InDet data preparation algorithms (trigger-specific configuration)
• Scheduler & decoration: Use case: algo1->A->algo2->A*->algo3 Need solution to ensure algo3 is scheduled only after decoration (A*).  Need DecorateHandle that creates alias for decorated collection?
