论文中 Data availability 是 not applicable 意味着数据不可用。根据文章，Data availability 是指制造商或数据持有者应根据用户的要求提供数据访问权限。当数据访问请求无法通过用户账户或产品或服务提供的配套移动应用程序等自动执行时，制造商应告知用户如何访问数据。此外，用户有权授权数据持有者向第三方服务提供商（如售后服务提供商）提供数据访问权限。对于微小型企业，这些义务将被豁免。第三章规定了适用于数据提供义务的一般规则。当数据持有者根据第二章或其他规定有义务向数据接收者提供数据时，应适用附件中规定的数据提供条件。当数据接收者认为数据提供条件具有歧视性时，数据持有者应证明不存在歧视。数据持有者不得在未经用户要求的情况下，向数据接收者提供排他性的数据访问权限。
