S Hodson and S Tykhonov - Building Trustworthy AI with Semantic Croissant and CDIF Framework

Semantic Croissant is an AI-ready research data infrastructure designed to connect distributed data sources such as research archives, statistical repositories, government databases, and international collections. It combines multiple data layers built on machine-readable metadata, ontologies, controlled vocabularies, and policy frameworks. Instead of centralizing data, it creates a federated knowledge network in which data remains with its original providers while becoming more interoperable and easier to use, with using Croissant for Machine Learning specification as navigation layer. The semantic layer of the system is the Cross-Domain Interoperability Framework (CDIF), which ensures consistent semantic alignment, standardized data exchange, and interoperability across domains.
