Data items in this category are as follows:

The bullet (![[\bullet]](/teximages/a1ach2o1/a1ach2o1fi16.svg)
) indicates a category key. The arrow (![[\rightarrow]](/teximages/abch3o1/abch3o1fi527.svg)
) is a reference to a parent data item.
Data items in the DIFFRN_DATA_FRAME category record details about each frame of data. An experiment may produce multiple frames of data and each frame may be constructed from data provided by multiple detector elements. Each complete frame of data is uniquely identified by the value of _diffrn_data_frame.id. The detector elements used are specified by values of _diffrn_data_frame.detector_element_id, which forms the category key together with _diffrn_data_frame.id. _diffrn_data_frame.detector_element_id is a pointer to _diffrn_detector_element.id in the DIFFRN_DETECTOR_ELEMENT category. The structure of the data in the frame is completed by giving values for _diffrn_data_frame.array_id (a pointer to _array_structure.id). The particular blocks of data in the frame are specified by giving values of _diffrn_data_frame.binary_id (a pointer to _array_data.binary_id).
