"description":"Reference from each frame (a frame is one section_single_configuration_calculation) in this section_frame_sequence to the corresponding section_single_configuration_calculation. Each section_frame_sequence binds a collection of section_single_configuration_calculation, because they all belong to, e.g., a molecular dynamics trajectory, or geometry optimization. The full information for each frame is stored in section_single_configuration_calculation and this metadata establishes the link for each frame.",
