The name part of the tuple is normalized and typed as :class:`NormalizedName`. The version portion is an instance of :class:`~packaging.version.Version`. The build number is ``()`` if there is no build number in the wheel filename, otherwise a two-item tuple of an integer for the leading digits and a string for the rest of the build number. The tags portion is a frozen set of :class:`~packaging.tags.Tag` instances (as the tag string format allows multiple tags to be combined into a single string).
