原文外掛簡介
NV oOS Content Graph transforms your WordPress content into a visual knowledge graph — organized, searchable, and interactive. Every post, page, category, tag, and author becomes a node; every relationship becomes an edge.
No API keys. No AI required. The core graph engine runs entirely on your WordPress server using your existing content. Optional remote sources (like Wikidata) are opt-in — see External services below.
What You Get
One-Click Graph Builder
Click “Build Graph” and ~10-30 seconds later, your entire site becomes a visual graph. Supports incremental rebuilds and scheduled cron updates.
Interactive Graph Explorer
Explore your content visually using Cytoscape.js. Search for nodes by label, click for details, zoom and pan. Color-coded by content type (posts, pages, terms, users).
Content Gap Analysis
Discover orphan content (no internal links), thin topic clusters, and missing link opportunities. Generate actionable content strategy recommendations.
Six Export Formats
Download your graph as JSON (NetworkX), GraphML (Gephi/yEd), CSV, Neo4j Cypher, Obsidian vault, or standalone HTML page.
Schema.org JSON-LD
Automatic structured data injection for SEO — taxonomy terms as about and internal links as relatedLink.
Related Content Widget
Appends graph-neighbor posts to your content based on knowledge graph proximity.
REST API
Full programmatic access with 14 endpoints. Read endpoints require the read capability (all logged-in users) or a valid guest token (guest tokens are provided by the NV oOS base plugin when installed); write endpoints require manage_options.
Extensible Tool System
14 built-in tools for graph operations: query, search, traverse, analyze, export. Addon plugins can register their own tools.
Addon Ecosystem (all optional)
nvoos-content-graph-ai — AI chat assistant with 13 AI providers, AI tools, embeddings, RAG, and agent memory
nvoos-content-graph-ai-platform — agents, skills, slash-commands, professions, A2A, ACP, and federation
Privacy Notice
This plugin does not collect, store, or transmit any personal data by default. The core graph engine runs entirely on your WordPress server using your existing content.
Remote Sources (opt-in only): When you explicitly configure a remote source driver (e.g. Wikidata, REST API, RSS feed), the plugin sends HTTP requests to the URLs you provide. No data is sent off-site without your explicit setup. Remote source credentials (API keys, tokens, passwords) are stored in the database encrypted with AES-256-GCM via the OpenSSL PHP extension, falling back to base64 encoding with an admin warning when OpenSSL is unavailable.
Optional AI Addons: The companion plugin nvoos-content-graph-ai (not included in this plugin) sends content to third-party AI providers (OpenAI, Google Gemini, etc.) when configured. Refer to that addon’s documentation for its privacy policies.
External services
This plugin does not require any external service for its core functionality. All graph data is computed and stored on your own WordPress server.
Wikidata (wikidata.org)
The optional “Resolve External Entity” tool and the Wikidata remote-source driver query the Wikidata API (https://www.wikidata.org/w/api.php) — only when you explicitly request an entity lookup by QID (e.g. Q42) or configure a Wikidata source.
What is sent: the QID or entity identifier you provide, plus standard HTTP request metadata (your server’s IP address, user agent).
When: only on your explicit request; never automatically or in the background.
What it is used for: fetching the entity’s label, description, and sitelinks so it can be ingested as a graph node.

User-configured remote sources (opt-in only)
When you configure a remote source driver (REST API, RSS/Sitemap feed, SPARQL endpoint, webhook receiver, etc.) in Settings, the plugin sends HTTP requests to the URLs you provide. What is sent depends entirely on the endpoint you configure. These requests happen only when you manually trigger a sync, schedule one, or receive a webhook. Remote source credentials (API keys, tokens, passwords) are stored in the database encrypted with AES-256-GCM via the OpenSSL PHP extension.
