Description
The increasingly large volumes of data generated at different synchrotron sources, such as PETRA III and the European XFEL, require a crucial shift from traditional bulk data transfers toward remote and slice-based selective data access. As part of the PHOTONIC (Photon Science - Harmonized Online Tools for Open, Navigable, Interactive Computing Framework) project, this work focuses on developing client-side libraries to integrate a unified API with established scientific software pre-existing at the photon sources. This project represents a framework that would enable researchers to perform real-time data slicing and the corresponding ad-hoc analysis directly within familiar environments such as H5Web and silx-kit [1]. Using the Liquid Interface Scattering Apparatus (LISA) instrument at the beamline P08 (DESY) as a primary use case, we aim to demonstrate how this integration facilitates the rapid evaluation of X-ray reflectivity (XRR) and grazing-incidence X-ray diffraction (GIXD) datasets [2]. The developed client library would include the Tiled data access service in the backend and would be utilized for transparent interoperability between different research facilities [3]. This would enable users to overlay and compare experimental datasets regardless of the underlying storage format. This contribution represents the architectural design of the client-side modules and discusses the implementation of FAIR (Findable, Accessible, Interoperable, and Reusable) data principles through professionalized software standards, including automated testing and standardized metadata handling. These developed tools would eventually lower the barrier for non-expert users and provide a scalable solution for remote scientific collaboration. This work complements the efforts of DAPHNE4NFDI [4] in advancing metadata catalogues and interoperability by enabling practical, fine-grained access to data that has been made findable.
