本站使用指南 — 面向 AI、机器人与数据科学家

本站为人类与机器同时设计。每个页面都有机器可读的对应资源，可通过内容协商或显式 URL 获取，整站知识图谱亦可查询。下文给出可直接复制运行的范例。

内容协商

本站各主页支持基于 Accept 头的内容协商——同一 URL，按需返回相应表示形式：

curl -H "Accept: application/ld+json"   https://blackcatinformatics.cn/
curl -H "Accept: text/turtle"           https://blackcatinformatics.cn/
curl -H "Accept: application/n-triples" https://blackcatinformatics.cn/
curl -H "Accept: text/markdown"         https://blackcatinformatics.cn/

每个页面（不仅是主页）亦可通过显式 URL 获取：

curl https://blackcatinformatics.cn/index.jsonld
curl https://blackcatinformatics.cn/index.ttl
curl https://blackcatinformatics.cn/index.md
curl https://blackcatinformatics.cn/llms.txt

/index.jsonld → JSON-LD · /index.ttl → RDF Turtle · /index.nt → N-Triples
/index.md → Markdown · /llms.txt, /llms-full.txt → LLM context (text/plain)

主页在边缘进行透明协商（Vary: Accept）；按页的显式 URL 始终可用。

知识图谱

本数据集当前公开 31 个 SKOS 概念、3 篇出版物与 2 项专利，多数以 Wikidata QID 锚定。主要实体均从根 JSON-LD 文档链接。公司节点为 #bii，人物节点为 #paudley。

使用的词汇表: Schema.org · FOAF · SKOS · DOAP · BIBO · vCard · PROV-O · OWL · Dublin Core · Wikidata.

SPARQL

整站知识图谱可通过 SPARQL 端点查询，并以 VoID 描述数据集元信息。示例查询——列出每个概念及其 Wikidata 锚定：

PREFIX skos: <http://www.w3.org/2004/02/skos/core#>
PREFIX owl:  <http://www.w3.org/2002/07/owl#>
SELECT ?concept ?label ?wikidata WHERE {
  ?concept a skos:Concept ; skos:prefLabel ?label .
  OPTIONAL { ?concept owl:sameAs ?wikidata }
}

curl -G https://blackcatinformatics.ca/sparql \
  --data-urlencode query@query.rq \
  -H "Accept: application/sparql-results+json"

/sparql — SPARQL endpoint
/.well-known/void.ttl — VoID dataset description

MCP

本站以 MCP（模型上下文协议）形式公开自身。将 MCP 客户端指向描述符，即可发现并调用只读工具查询本站结构化数据：

https://blackcatinformatics.ca/.well-known/mcp.json

/.well-known/mcp.json — MCP server descriptor
/webmcp.js — in-page WebMCP bridge
/.well-known/agent-policy.json — agent usage policy
/.well-known/agent-skills/ — published agent skills

运行模式

调用示例

/mcp 是一个有状态的 streamable-HTTP JSON-RPC 端点：会话先以 initialize 握手并进行能力协商，随后在后续每个请求中复用服务器返回的 Mcp-Session-Id 响应头，并回传协商所得的 MCP-Protocol-Version 头。最简单且正确的客户端是 MCP Inspector——规范推荐用于 Streamable HTTP 服务器的首选调试工具，它会替你处理握手、能力协商、会话与 SSE 传输：

# Recommended — the Inspector manages initialize, capabilities, the
# Mcp-Session-Id, the MCP-Protocol-Version header, and the SSE transport:
npx @modelcontextprotocol/inspector      # then connect to https://blackcatinformatics.ca/mcp

# Raw JSON-RPC, for reference. The session is stateful, in order:
#   1. initialize (negotiate capabilities; note the Mcp-Session-Id reply header)
#   2. notifications/initialized
#   3. tools/list      4. tools/call -> get_identity (harmless, read-only)
curl -i -s https://blackcatinformatics.ca/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-11-25","capabilities":{},"clientInfo":{"name":"curl","version":"0"}}}'

# ← server reply (headers + result, elided):
#   HTTP/1.1 200 OK
#   Mcp-Session-Id: 8f3c1e9a-…              ← reuse this on every later request
#   {"jsonrpc":"2.0","id":1,"result":{
#     "protocolVersion":"2025-11-25",
#     "capabilities":{"tools":{"listChanged":true}},
#     "serverInfo":{"name":"blackcatinformatics.cn site agent","version":"0.2.0"}}}

# Every request AFTER initialize MUST echo BOTH the session id and the
# negotiated protocol version:
curl -s https://blackcatinformatics.ca/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Mcp-Session-Id: 8f3c1e9a-…" \
  -H "MCP-Protocol-Version: 2025-11-25" \
  -d '{"jsonrpc":"2.0","method":"notifications/initialized"}'

# then list the tools (same two headers):
#   -d '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'
# ← {"jsonrpc":"2.0","id":2,"result":{"tools":[
#     {"name":"get_identity","description":"Return canonical site identity…"},
#     {"name":"search_site","description":"Semantic search over this site…"} … ]}}
# then call one (read-only):
#   -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"get_identity","arguments":{}}}'
