## Detailed Description

A RecordDataSvc is the base class for event services.

When a new datafile is opened the data service retrieves an incident from the persistency area (currently only from POOL) together with an opaque address describing the record. These history records are put onto the run-records datastore under the name of the logical file (FID): /Records/<FID>/.....

Hence, each history records can be addresses the same way: /Record/<FID> (/EOR)

StatusCode RecordDataSvc::initialize | ( |  | ) | `[virtual]`

Service initialisation.

We need to subscribe to 2 incident: 1) FILE_OPEN_READ: fired by conversion service on open file 2) IncidentType::BeginEvent fired by event loop BEFORE the event processing starts. Do everything to bootstract access to the old event record.
