Data Quality assurance is an essential task to provide consistency, accuracy, reliability and reproducibility of scientific results [C1], [C2], [C3], [C4].

DQuality is a python toolbox to asses the quality of raw and processed data collected at the Advanced Photon Source (APS).

DQuality verifies that all experiment components EPICS Process Variables (PVs) like motor positions, storage ring parameters etc. are valid and their values are within a predefined range.

DQuality verifies that the raw data files saved in the Data Exchange hdf5 file format contain a valid data and meta-data structure and that existing dependencies between the data and meta-data structure are correct.

DQuality provides live monitoring of the above functionalities for all raw data created in the active directory.
