• The calib directory is a top level DCS directory.
• Detector type <dettype> folder is used to organize files under the calib directory. In case of direct access to the hdf5 file the detector type is duplicated in the name of the file.
• Unique part of the detector name <detid> is used to assign calibration file to the particular detector version. If the detector is changing a new calibration file is created with new <detid>.
• Information about predecessor and successor (if available) can be saved under the root level of the calibration file.
• Current sources (ex: 'Camp.0:pnCCD.1' ) should be presented in the dictionary of aliases.
