 ARC is a community-driven initiative that mirrors the flexibility required to manage research data effectively in real-world scenarios.
 To support the agility needed by developers and to enable them to concentrate on creating specialized tooling for their respective research domains, the ARC core team — supported by the NFDI DataPLANT — offers a comprehensive development library tailored for a wide range of ARC-related operations.
 [ARCtrl](https://github.com/nfdi4plants/ARCtrl) is a robust software library designed to standardize and simplify the handling of ARCs.
