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.

In addition serveral other have been added, see [SciCat Instances](https://xwiki.desy.de/xwiki/bin/view/IT/SciCat/CICD%20Setup/). These help to identify missing features and adopt SciCat to DESY needs.

15 +* Introduce standardised way of defining meta data, FS-EC (under Linus Pithan).
16 +* Use SciCat to help book keeping of what was measured which also helps planning new research studies.
17 +* Use SciCat to issue DOIs: Together with the DESY library develop detailed workflow to help the user make data publication.
18 +* Use SciCat to provide access to experimental data that comply with DESY photon science data Policy and can be made available through DESY resources.

26 +The system is set up such that an internal and public, outward facing SciCat is provided. Into the internal, several PETRA beamlines ingest directly their metadata during beamtime that are P08, P05, P65. The URL is

30 +It is connected to the external catalogue, fsdata.desy.de, on which DOIs can be minted for selected datasets from the internal catalogue.
