CTMinfo is an ontology-based system designed to achieve 100% verified and reliable data across industrial, trade, and engineering domains.Unlike Big Data approaches that accumulate unverified information, CTMinfo introduces the concept of SmallData — a model built exclusively from verified and logically consistent entities. The system establishes a structural ontology ensuring the full traceability of each object, its origin, and transformation throughout the production and supply chain. This approach eliminates ambiguity, duplication, and corruption in data management. CTMinfo also introduces the principle of OpenTech, emphasizing open, structural, and transparent technological development as an alternative to opaque “deep-tech” systems. The project demonstrates how a precisely defined ontological framework can serve as a universal infrastructure for verified industrial information, creating a foundation for trustworthy AI, automation, and sustainable economic systems.
