UAI-1 C# Website Support Kit

This page publishes the Protocol5 NuGet package and starter ZIP for getting a working UAI endpoint onto a C# website in minutes. The package is the reference implementation path for install, load, validate, export, route, render, and test.

What the package now covers

Install the package into an ASP.NET Core site
Load canonical examples and discovery assets from the package
Validate UAI-1 JSON against the canonical schema and reference validator
Export HTML into canonical .uai.json
Route canonical machine artifacts such as /UAI-1.json and /schema/uai-1.schema.json
Route page-specific UAI endpoints such as /docs/hello/index.uai.json
Render UAI-1 back to HTML
Test endpoint output with the same parser and validator used by the package

Quick start

Install from NuGet:

dotnet add package Protocol5.UAI.CSharp

Then wire it into an ASP.NET Core site:

using Protocol5.UAI;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddProtocol5UaiWebsiteSupport();

var app = builder.Build();
app.UseProtocol5UaiWebsiteSupport();
app.MapProtocol5UaiCanonicalArtifacts();
app.MapProtocol5UaiHtmlEndpoint(
    "/docs/hello/index.uai.json",
    static () => "<html lang=\"en\"><body><h1>Hello UAI</h1><p>Ready in minutes.</p></body></html>",
    new UaiHtmlTranslationOptions
    {
        SourceUri = "https://example.org/docs/hello",
        DocumentId = "docs-hello",
        PageType = "article",
        SiteName = "Example"
    });

app.Run();

That setup gives you a working page endpoint plus the canonical embedded machine artifacts exposed by the package.

Validate

var document = new UaiDocumentParser().Parse(json);
var validation = new UaiDocumentValidator().Validate(document);
if (!validation.IsValid)
{
    throw new InvalidOperationException("UAI validation failed.");
}

Load, validate, and emit canonical JSON

var loader = new UaiCanonicalAssetLoader();
var exampleJson = loader.LoadExampleText("homepage.uai.json");
var schemaValidation = new UaiSchemaValidator().ValidateCanonicalJson(exampleJson);
if (!schemaValidation.IsValid)
{
    throw new InvalidOperationException("Canonical validation failed.");
}

var example = loader.LoadExampleDocument("homepage.uai.json");
var validation = new UaiDocumentValidator().Validate(example);
var canonicalJson = UaiDocumentSerializer.Serialize(example);

Export

var exporter = new UaiHtmlExporter();
var export = exporter.ExportToFile("Pages/hello.html", "wwwroot/docs/hello/index.uai.json", new UaiHtmlTranslationOptions
{
    SourceUri = "https://example.org/docs/hello",
    DocumentId = "docs-hello",
    PageType = "article"
});

Render

var renderedHtml = new UaiHtmlRenderer().Render(export.Document);

Test

var json = await client.GetStringAsync("/docs/hello/index.uai.json");
var document = new UaiDocumentParser().Parse(json);
Assert.IsTrue(new UaiDocumentValidator().Validate(document).IsValid);

HTML recommendation

If a page is meant to declare UAI-aware content directly, use:

<html lang="x-uai-1">

And pair the human page with the machine endpoint:

<link rel="alternate" type="application/uai+json" href="/docs/hello/index.uai.json">

Canonical formatting rule

When serializing canonical UAI values, always use InvariantCulture:

using Protocol5.UAI;

var confidence = 0.875m.ToString(UaiCultureInfo.CanonicalSerializationCulture);

Radix 63404 examples included in the kit

Radix63404.Encode(41);        // simple single-glyph id
Radix63404.Encode(5651);      // sample two-glyph id
Radix63404.Encode(267914296); // sample three-glyph id
