The data of the ZEUS experiment at HERA and their usage have been converted to "preservation mode" in 2012, and new physics results have continuously been published from these data since then.
A description will be given of the original plan, its implementation, the latest status of data, software and knowledge access, some corresponding results, and the related challenges.
I will give a quick update on the FAIR and Open Data portal public-data.desy.de to outline how we employ metadata schemata for validated ingestion before community curation and finally show that we can mint DOIs that resolve data locations directly
Data access is an essential component of the scientific process, as is the storage system where that data resides. There is no one-size-fits-all solution, which makes selecting the right storage system a non-trivial task.
In this presentation, I will briefly overview the file and storage systems used at DESY and offer guidelines for matching different workloads to appropriate storage solutions.
