Description
When gathering your analog research data and metadata, including challenging-to-digitize experimental parameters, aiming at creating a knowledge graph, we suggest the following pipeline for achieving high data quality: agreeing on a shared vocabulary, expanding it to an ontology and eventually semantically annotating the recorded data.
To facilitate this pipeline we developed and use the following tools: The first one, VocPopuli, is the entry point for domain experts. VocPopuli enables the collaborative definition and editing of metadata terms and assigns a PID to each term in the vocabulary, as well as the vocabulary itself. After the export as a SKOS vocabulary or OWL classes, these can be completed to a full ontology by adding relationships. Examples are PolyMat and PolyLab, two domain ontologies for membrane research. Extending ontologies with SHACL shapes creates forms in the Electronic Lab Notebook (ELN) Herbie which automatically make the recorded research data globally understandable and meaningful by semantic enrichment, and ensuring local conformance and completeness of the data by running validations. Managing RDF graphs makes Herbie a platform for collaborative editing of a shared knowledge graph.
However, interdisciplinary research institutions often employ various ELNs systems, creating barriers to metadata exchange. Addressing this interoperability gap, we have developed ELNdataBridge, an API-based data exchange, to enhance interoperability between ELNs, in our case Herbie and Chemotion. ELNdataBridge handles the mapping of the ELN entry fields, as well as the synchronization routine, which can be configured via a user-friendly web interface. An extension to other ELNs can be easily achieved.
Completing the pipeline from vocabulary terms to data exchange between ELNs enables semantically linked and FAIR research metadata and data management, ready for future exploration.
