ontosphere

概述

Ontosphere 是一个基于浏览器的 RDF/ontology 知识图谱编辑器，可以从文件、URL 或 SPARQL 端点加载数据。它提供可视化画布来创建和编辑节点与边，执行 OWL-RL 推理，并应用多种布局算法。MCP 服务器集成为 AI 代理提供了与知识图谱交互的工具，包括加载数据、查询图谱、更新节点和链接以及运行推理操作。所有计算都在浏览器中使用 Web Workers 在客户端完成。

FAQ

如何将 AI 代理连接到 Ontosphere？

Ontosphere 通过浏览器的 navigator.modelContext API 暴露 MCP 工具。您可以使用 Claude Code 与 Playwright 进行完全自动化连接，或使用 AI Relay Bridge 连接 ChatGPT、Gemini 和 Claude.ai。

Ontosphere 支持哪些推理功能？

它使用 N3.js BGP-only Reasoner 在浏览器中运行 OWL-RL 推理。支持 rdfs:subClassOf 传递性、owl:equivalentClass、owl:someValuesFrom 限制、owl:inverseOf 等 OWL 构造，但不支持需要 EYE 推理器的完整 OWL-RL 功能。
