FAIRmat Community Meets Technology Partners Workshops

2nd Workshop:

January 24-25, 2024, in Berlin and online

Building a community for FAIR photoelectron spectroscopy metadata

During the first workshop on standardizing photoelectron spectroscopy data, we identified relevant questions that needed further exploration. Building on this foundation, our second workshop, held on 24-25 January, was a pivotal gathering for discussing the advancements made over the preceding seven months involving the community and our technology partners. The workshop was attended by sixty participants from diverse sectors, including corporations and academic institutions, with expertise in experimental and theoretical domains. It showcased various photoemission spectroscopy (PES) equipment from leading international manufacturers, including FOCUS, SPECS, Scienta Omicron, Thermo Fisher Scientific, and Surface Concept. Additionally, the event attracted international attendees from European institutes with a strong presence of large beamline facilities (Diamond, SLS, ALBA, BESSY).

The workshop aimed to foster a collaborative community spirit with the shared objective of refining and finalizing a general storage format for PES data and metadata. Our collective effort seeks to produce a comprehensive draft by September 2024 in anticipation of the standard's evaluation by the NeXus International Advisory Committee (NIAC). Being part of NIAC and its role in facilitating NeXus standards will encompass our photoelectron spectroscopy standard.

Our application definition, NXmpes, is poised to transition into a fully recognized standard following a one-year incubation period, with the expectation of being officially endorsed as the preferred format for data interchange and interoperability by September 2024. This milestone is a testament to our technical achievements and the vibrant interest and commitment displayed by our community.

The enthusiastic participation and feedback from the workshop participants have been incredibly encouraging. As we venture forward, we are sustained by the prospect of cultivating a robust community-driven initiative. We aim to establish the first standard that will serve as a foundational pillar for FAIR (Findable, Accessible, Interoperable, and Reusable) data principles in photoemission spectroscopy, marking a significant stride towards enhancing data handling and analysis within the field.

1st Workshop:

May 11-12, 2023, in Berlin and online

Community agrees on NXmpes

Photoelectron spectroscopy users from several research institutes and technology partners from industry came together in a workshop on 11-12 May 2023 organized by FAIRmat.

This was our second community meets technology partners workshop, after the successful ellipsometry meeting in September 2022. The hybrid event provided an opportunity to discuss FAIR data management and the specific technical solutions developed within FAIRmat for standardizing data and metadata storage and exchange in photoelectron spectroscopy experiments.

This kick-off event successfully aligned the scientific photoelectron spectroscopy community and its technology partners towards the goal of FAIR data handling. We had a broad discussion on the general process of standardization and reviewed in detail the application definition for multidimensional photoelectron spectroscopy, NXmpes, which is being developed within FAIRmat for the NeXus standard, a community standardization platform with a controlled vocabulary and defined relations between hierarchically organized entries. The application definition has already been accepted by the NeXus International Advisory Committee (NIAC) and released as a contributed definition. Following up on this kick-off meeting, suggestions for improvements are still being collected and the discussions with the technology partners will continue in September. Our technology partners are also interested in extending the scope and start collaborating in a VAMAS projects on industry standards for ISO, DIN. Future topics will include a common effort on further refinement of the NXmpes definition based on community feedback and the deveelopment of derived specialized experiment application definitions, e.g., for XPS, ARPES, liquidjet photoelectron spectroscopy, and time-resolved techniques.

It was great to see the strong interest of photoelectron spectroscopy users along with their technology partners on developing standards. FAIRmat is happy to celebrate the success of the second workshop in our “Community Meets Technology Partners” series and will promote similar interactions and discussions with the scientific and industrial communityon FAIR data management and standardisation for other experimental fields and a wider range of the German materials science community
