Usage

Parse a schema:

var schema = JsonSchema.FromText(content);

Load one from a file:

var schema = JsonSchema.FromFile(filename);

Directly deserialize it:

var schema = JsonSerializer.Deserialize<JsonSchema>(content);

Or build it explicitly in code:

var schema = new JsonSchemaBuilder()
    .Comment("a comment")
    .Title("A title for my schema")
    .Type(SchemaValueType.Object)
    .Properties(
        ("foo", new JsonSchemaBuilder()
            .Type(SchemaValueType.String)
        ),
        ("bar", new JsonSchemaBuilder()
            .Type(SchemaValueType.Number)
        )
    )
    .Build();

Use the schema to evaluate and annotate data:

var instance = JsonNode.Parse("{\"foo\":\"a value\",\"bar\":42}");
var results = schema.Evaluate(instance);
