- Detector name consists of a common part <dettype> and unique part <detid>.
- Alias to the detector name should be kept in separate dictionary outside the scheme.
- Each detector may have optional predecessor, successor, and other tags in the dictionary.
- Calibration type folders contain info about calibrations of particular type, ex: pedestals, rms, status, mask, background, etc.
- Each calibration type contains a set of time stamp ranges defining calibration validity range. If the second time stamp of the range is missing it is considered as infinity (by the end).
- The time stamp range folder contains tstamp_begin, tstamp_end (int) values, dictionary of tags associated with this folder, reference to the default calibration, and folders with calibration versions, distinguished by there production time stamp.
- The number of calibration versions for each time stamp range is not limited. Default calibration is defined by the reference default_version.

TBD
Open questions
- What is included in the detector Id version? FEE version, controller version, etc?
- when constants are updated (file open to write) they are not available... Lock to resolve.
