This is the full description of the proposal referred to by GitHub issue #6 in the PDBX/mmCIF working group repository on the PDBx mmCIF dictionary extension for diffraction data sets.
Below is an example of the definition of the processing of a complex data collection, based on PDB entry 4MU9. It uses (with some modifications) the proposed PDBx mmCIF dictionary extension for diffraction data sets. The image data are available from the JCSG. The data collection was a 3-wavelength MAD experiment made up of 5 sweeps. Going by the image timestamps the first two sweeps were wavelength-interleaved with a wedge size of 15° (=60 images of 0.25°). For illustrative purposes I show an interleavin
