HOMER (HPMC Tool for Ontology-based Metadata Extraction and Re-use) is presented in this video as a service for researchers working in high-performance measurement and computation (HPMC). Developed within the NFDI4ING archetype DORIS, HOMER automatically extracts research metadata from script-based HPC workflows and supports standardized, ontology-based documentation and publication of research data. The video also demonstrates how HOMER can support the work of a typical HPC user by simplifying metadata extraction and research data documentation.
