It is used at many large European facilities before it came to DESY in January 2022, like PSI, ESS, MaxIV. 4 4 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. 6 6 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. 8 8 9 - Togain experience so-called _demonstrator beamlines_ where chosen, in 2021 when SciCatwaschosen atDESY to be tested.

Useful means - among others - 14 14 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 access experimental data that comply with DESY Policy and can be made available through DESY resources. 19 -* Provide technical support. 21 +* introduce standardised way of defining meta data, FS-EC (under Linus Pithan) 22 +* use SciCat to issue DOIs: in agreement with L start setting up a workflow (involved IT-RIC Tim W) 23 +* provide technical support for instances (IT-InFa) 20 20 21 -### MilestoneachievedbyJanuary2026:25 +### Step by Step DOI minting for Photon Science 22 22 23 -Set up of the system to mint DOIs. 24 - 25 -## Step by step guide for the Photon Science DOI minting Service 26 - 27 -The system is set up such that provide an internal and public, outward facing SciCat.
