3 3  SciCat stands for “Science Catalogue” and is generally used as a metadata catalogue for finding back data, addressing thereby the needs of a growing photon and neutron science community. It is used at many large European facilities before it came to DESY in January 2022, like PSI, ESS, MaxIV.

5 5  The challenge in photon and neutron science is to find a standard way of naming characteristics for a huge variety of experiments at beamlines, interconnecting several fields like chemistry, material science, biology, medicine, etc – covering many aspects that influences daily life. Apart from the "normal" physics research there are various other types of research depending on the purpose one can perform at DESY: inhouse, commissioning, industries. In additon, there are differences from PetraIII and FLASH within photon science. All this is reflected in the different treatment of the data taken.

7 -One of SciCats strengths is that technically one can impose your own schema, the fields to describe your use case. These pages describe the current state of SciCat. The ultimate goal is to have a production system of SciCat that serves all beamlines.
7 +One of SciCats strengths is that technically one can impose your own schema, the fields to describe your use case. Many efforts were made at the European scope to use standardised vocabulary such that scientific metadata can be gathered and made findable, accessible and interoperable at first and ultimately reusable, eg. in NFDI and EOSC framed projects. DESY's SciCat system follows those standards.

9 +To gain experience so-called _demonstrator beamlines_ where chosen, in 2021 when SciCat was chosen at DESY to be tested. These were: P08 and FLASH. In the next two following years, serveral other have been added, see [SciCat Instances](https://xwiki.desy.de/xwiki/bin/view/IT/SciCat/CICD%20Setup/). These helped to identify missing features and adopt SciCat to DESY needs.
