“All things data” Webinar: Pitschi – Particle Image depoT using Storage Caching Infrastructure by Dr Rubbiya Ali and Dr Hoang Nguyen
Scientific imaging instruments with modern fast CMOS detectors are generating increasingly large datasets, and hence, data management becomes more critical. This is particularly true in the context of large multiuser facilities such as the Center for Microscopy and Microanalysis (CMM) at UQ as it operates a wide range of microscopes and many of them are big data producers. A central data repository to store, index, annotate data not only allows its researchers to search, browse and retrieve their data easily but also has the potential to harvest metadata to enrich these datasets.
Pitschi is a central data repository for CMM scientific instruments that adheres to FAIR data principles. This is part of the Australian Characterisation Commons at Scale project, which is funded by the Australian Research Data Commons. Pitschi is based on the opensource Clowder data management framework from the National Center for Supercomputing Applications in the US, and it is fully integrated with the instrument booking system and the storage infrastructure at UQ. Pitschi provides end-to-end process data management, from capturing raw data to transferring them to storage collection and finally ingesting/indexing the data into the repository. As part of the ingest process, metadata of supported file types are extracted automatically. These metadata are then used to facilitate search and discovery. Once the data are ingested in Pitschi, they are available in various platforms such as HPCs, personal computers, and processing platforms such as CVL. Data transport is arranged transparently using the Metropolitan Data Caching Infrastructure (MeDICI).
In March 2021, we presented our evaluation of data repositories to Microscopy Australia's Data Management and Informatics Committee. In this follow-up webinar, we would like to share our experience in the development and operation of Pitschi.
