        IFC data may be associated with an authoring application to identify
        which application was responsible for editing or authoring the data. An
        application is defined by the developing organisation, as well as a full
        name and identifier. This is akin to how web browsers have an
        identification string.

        :param application_developer: The IfcOrganization responsible for
            creating the application. Defaults to generating an IfcOpenShell
            organisation if none is provided.
        :type application_developer: ifcopenshell.entity_instance.entity_instance, optional
        :param version: The version of the application. Defaults to the
            ifcopenshell.version data if not specified.
        :type version: str, optional
        :param application_full_name: The name of the application
        :type application_full_name: str, optional
        :param application_identifier: An identification string for the
            application intended for computers to read.
        :type application_identifier: str, optional
