Google Cloud has released the Open Knowledge Format (OKF), an open standard for passing context to AI agents that models knowledge bases as a directory of Markdown files with YAML metadata. The format requires only a single mandatory field (type) and links files via standard Markdown links to form a unified knowledge graph. It is platform-agnostic and readable by both LLMs and text editors. The specification and reference implementations—including an HTML visualizer and a BigQuery dataset parsing agent—are available on GitHub, with OKF support also announced for Google Cloud Knowledge Catalog.
