Provide modular, open-source and flexible analysis toolkit components for associated workflows to enable rapid, reproducible and scalable analysis of the large-volume and complex data products created by current, and future, radio and millimetre astronomical research infrastructures (RIs). These toolkit components will enable user exploitation of innovative techniques (such as AI/ML and Bayesian inference), translate knowledge and developments between different RIs; and provide RI science users with the elements of workflow implementations that will allow them to exploit, and contribute to, cutting-edge industry and academic-driven high-performance compute advances such as GPU, tensorcore, distributed compute and cloud environments.
