// Overview

vcpkg curated registry (ports and version baseline)

Microsoft's vcpkg C and C++ package registry publishes port manifests and versions/baseline.json, which maps every library to its current version and port revision.

Verdict

A C and C++ package index for software inventory work, alongside pypi-json-api. Licence: MIT: the repository licence file is the "MIT License", "Copyright (c) Microsoft Corporation". The libraries keep their own licences. The files are hosted on GitHub, whose Terms of Service say "these Terms do not restrict lawful access to or use of the contents of public repositories by third parties"; the Acceptable Use Policies limit excessive automated bulk activity, not ordinary reading of public files. GitHub's Access Reciprocity clause applies to automated collection for training a commercial AI system (see the licence note). Rate limits: Not stated. Signal Lab links only.

Ask your agent

Fetch https://signal-lab.qdt.ai/catalog.json, find slug "vcpkg-registry" and read its licenseNote. The files are MIT and hosted on GitHub, whose terms do not restrict lawful access to public repository contents. GitHub's Terms of Service section D.9 (Access Reciprocity) say: "By using automated means to access, collect, or otherwise use (“Access”) any publicly accessible Content from the Service for the purpose of developing or training any commercially available artificial intelligence model, machine learning system, or similar technology (a "Commercial AI System"), you hereby waive any and all policies, terms, conditions, or contractual provisions governing products, services, websites or datasets you own or operate that would otherwise prohibit, restrict, or place conditions upon GitHub's Access to any publicly accessible data, information or content associated with your products or services, including for the purpose of developing or training any Commercial AI System." So if I use these files with automated means to develop or train a commercial AI system, tell me that clause applies. Otherwise, write code that downloads the vcpkg versions/baseline.json (for example https://raw.githubusercontent.com/microsoft/vcpkg/master/versions/baseline.json) when I run it, keep request volume modest, and keep the licence notice with any copies.
