bkn-foundry

BKN Foundry is the technical backend of OpenBKN, an ontology-driven business knowledge network platform. It provides unified data access, safe execution, and governance for AI agents operating in real business environments. The repository includes deployment scripts, a CLI-based administration interface, and a Markdown-based modeling language (BKN Lang). It is backend-only, with no web UI; interactions are via CLI, SDK, or API. Key components include the BKN Engine (context loader and ranker), VEGA (data virtualization), Exec Factory (tool/MCP/skill orchestration), BKN Safe (access control and auditing), and BKN Trace (evidence chain tracing). The project claims improvements in context accuracy, token cost reduction, and safe execution through explainable decisions and traceable evidence chains. The README provides quick-start instructions for deploying on Linux (with optional macOS dev setup), including preflight checks, installation, and post-install bootstrap. It also documents the OpenBKN SDK (CLI and TypeScript SDK) and authentication methods for headless environments. Benchmarks compare BKN Foundry against other RAG platforms on accuracy, latency, and token usage, with ablation studies on retrieval depth, schema preloading, tool curation, and path guidance.
