Johannes Demer enhanced the GAIA-X4PLC-AAD/ontology-management-base repository by developing and refining ontologies for marketplace data contracts and asset metadata. Over two months, he restructured data and contract semantics, improved SHACL validation, and standardized naming conventions to support reliable integrations and onboarding. His work introduced new classes and SHACL shapes for file metadata and asset dimensions, enabling richer and more consistent asset descriptions. Using technologies such as RDF, SHACL, and Turtle, Johannes focused on reducing ambiguity and improving data quality. The depth of his engineering addressed both domain modeling and validation, resulting in a more robust and maintainable ontology management system.

Dec 1, 2024In December 2024, the team delivered a major enhancement to the ontology-management-base by introducing a comprehensive Asset Metadata Schema and Validation Enhancements. The changes establish new classes for file metadata and dimensions, add SHACL shapes for file properties, and introduce a DimensionsShape to describe asset dimensions. The LinkShape was refined to include file metadata and validation rules for URI, IPFS CID, MIME type, size, and filename, enabling more accurate and consistent asset descriptions. The updates are tracked in GAIA-X4PLC-AAD/ontology-management-base with commit 9bbb3262a0188e8e6d3a62f0989b203cec0a0233 ("update domain").
