Overview

W3C Standard XML Namespaces

These namespace classes represent the standard W3C-defined XML namespaces that have special semantics and reserved prefixes.

Per W3C specifications:

  • xml: prefix is ALWAYS bound to www.w3.org/XML/1998/namespace

  • xsi: prefix is conventionally used for XMLSchema-instance

  • These prefixes should never be overridden

Instance Method Details

#const_missing(name) ⇒ Object

Automatically register types when a constant is accessed via const_missing. This ensures symbol-based type access works even if autoload order causes w3c.rb to load before lutaml-model’s Type module.

def const_missing(name)
  register_types!
  const_get(name)
end

#register_types! ⇒ Boolean

Register all W3C types with the Type registry. Called lazily when types are first accessed.

Returns:

  • (Boolean) —

    true if registration succeeded or already done

def register_types!
  return true if @types_registered && registered?

  if defined?(Lutaml::Model::Type)
    W3C_TYPES.each do |symbol, type_class|
      Lutaml::Model::Type.register(symbol, type_class)
    end
    @types_registered = true
  end
  @types_registered
end

#registered? ⇒ Boolean

Check if W3C types are actually registered in the Type registry.

Returns:

  • (Boolean) —

    true if all W3C types are registered
