+| [OKF v0.1](https://github.com/GoogleCloudPlatform/knowledge-catalog/tree/main/okf) (Open Knowledge Format) | Google Cloud's engineering spec for the "LLM Wiki" idea. A KB is a directory of Markdown files with YAML frontmatter. Emphasizes structured, portable, tool-agnostic knowledge units. WikiLoop bundles are OKF-conformant. |
+| YAML frontmatter schema | Knowledge unit identity card: `type` (sop / metric / template / case / decision / risk / glossary), `title`, `description`, `source`, `tags`, `updated_at`, `status` (active / outdated / draft). |
+| Knowledge unit + relations | Each unit is a standalone Markdown file; relations expressed as Markdown links — forms a navigable knowledge map for agents. |

+| [OKF v0.1](https://github.com/GoogleCloudPlatform/knowledge-catalog/tree/main/okf)（Open Knowledge Format，开放知识格式） | Google Cloud 对 "LLM Wiki" 想法的工程化规格。知识库是包含 YAML frontmatter 的 Markdown 文件目录，强调知识的结构化、可携带性和工具无关性。WikiLoop 知识库与 OKF v0.1 兼容。 |
+| YAML frontmatter Schema | 知识单元的"身份证"：`type`（sop / metric / template / case / decision / risk / glossary）、`title`、`description`、`source`、`tags`、`updated_at`、`status`（active / outdated / draft）。 |
+| 知识单元 + 关联 | 每个知识单元是独立的 Markdown 文件；关联关系用 Markdown 链接表达而非文件夹层级——形成供 Agent 导航的知识地图。 |
