Herbie is developed at the Helmholtz-Zentrum Hereon as an open-source and modular ELN to interlink heterogeneous process chains in research. It is ideally suited for labs with fabrication and characterization processes that are standardised or performed repetitively, e.g. for materials sciences. To achieve comparability, quality assurance, and reusability, users enter data in wellstructured, pre-defined webforms for each process or entity type. These webforms are automatically generated from ontologies, defined in OWL (Web Ontology Language) and SHACL shapes (Shapes Constraint Language). Through the integration of ontologies, all inserted data is semantically annotated and the webforms are thoroughly interconnected, reflecting the complete lifecycle of a sample. Thus, all entered information is easily accessible in various contexts, such as in a chronological journal, filtered for the linking entities like projects or equipment, or in a tabular database. Users can create, view, update or delete entries via the graphical web interface or its REST API. File export, file import and the API embed Herbie conveniently into linked-data software ecosystems.
