OiO MetaData-Model Engine is a core modeling platform for oil & gas. Built on patented “Minimum Business Node” and “Business Coordinate” concepts, it standardizes and unifies workflows with structured modeling. By bridging business logic and data flow, it improves efficiency and consistency, serving as a foundation for intelligent, integrated operations.
The OiO Node Definition Standard Library is a standardized knowledge framework for oil & gas, built on the meta-model engine. Covering exploration, development, production, and drilling, it defines over 80,000 business nodes and 20,000 minimum work nodes in detail. As an extensible framework, it enables unified modeling, data governance, and intelligent decision-making—key to digital transformation.
OiO-KG is a knowledge graph system built on the meta-model engine and node standard library, following a standards-driven approach. It models complex workflows into structured, visual representations for centralized, traceable, and shareable knowledge. By automatically transforming standard definitions into graph structures, it ensures consistency and lays the foundation for semantic search, reasoning, and intelligent decision support.
