Description
The Advanced Photon Source Data Management System (DM) now provides a web-based user interface. DM is responsible for managing experiment data for facility users by providing capabilities related to storage, access, transfer, metadata, and processing. Previously, users interacted with DM through a command line interface, Python API, or PyQt desktop GUI available locally on workstations at each beamline. The new DM web portal is built on the existing Python API and the Django Globus Portal Framework (DGPF). It introduces role-based access so APS users can only interact with their own experiments while providing access to all experiments and additional features for beamline staff. The web portal includes features available in the GUI to create and edit experiments, edit user access, start and monitor data transfers, view file statistics, and monitor processing jobs. The web portal expands on these features with additional improvements of the ability to view file metadata, start new processing jobs, monitor status of DM services and HPC resources, and archive or restore datasets from tape. Each experiment page links to Globus for more convenient data sharing. Future developments will include a live view of data streams, interactive data visualization, and a monitoring dashboard for local PBS queues.
