NVIDIA GitHub Pages is a hub for hosting project documentation and sitemap data for NVIDIA's open source initiatives. The site serves as a central point where each project can publish its own documentation, sitemaps, and fallback redirects. By consolidating these resources under a single domain, the site keeps access predictable and consistent for developers working on AI factories, robotics, and autonomous vehicles.

The page is designed to be convenient for project maintainers who need to publish sitemap files that list the canonical URLs for their documentation. A project documentation site can create a sitemap such as `https://nvidia.github.io/ProjectName/sitemap.xml`, and the main index will reference it with an XML `<sitemap>` entry. The index itself is an XML sitemap index following the sitemaps.org schema, containing only `<sitemap>` entries that point to the individual project sitemaps. All URLs must be absolute HTTPS links with exact capitalization. The site also requires that the project's sitemap use a `<urlset>` section that lists the page URLs. This structure ensures Google's sitemap crawler can discover all relevant pages without additional configuration.

Fallback redirects are handled by editing a JavaScript object in the `404.html` file. The key of each entry is the first path segment after the domain (e.g., `OldProject`), and the value is the full destination URL (e.g., `https://nvidia.github.io/NewProject`). When a user requests a nonexistent path under the old project segment, the browser receives the redirect mapping and appends the rest of the path, query string, and fragment to the new base URL. This method does not generate HTTP 301 or 308 responses; instead, the redirect logic runs client‑side. The site also maintains a `robots.txt` that points to the root sitemap index, so adding new projects requires no changes to that file.

Key features

• Central repository for managing sitemap indexes for all NVIDIA projects.
• Simple XML structure that lists `<sitemap>` tags referencing individual project sitemaps.
• Client‑side redirects defined in `404.html` to map old project paths to new ones.
• Requires HTTP 200 responses and valid sitemap XML for all referenced files.
• Supports nested path elements, query strings, and fragments in redirect handling.
