The DFLD Storage Media should also beannotated with the originator identification and quality/conformity markings.The Electronic Distribution of DFLD should recognise these points andprovide an equivalent level of control agreed by the Director-General. Theresponsibility of obtaining appropriate confirmation of the authenticity,performance specification and accuracy of the DFLD rests with the operator.It is also recommended that a "confidence" check of the received data beaccomplished to ensure that the new data satisfies the intended use. TheDFLD should be subjected to a configuration control process acceptable to theDirector-General.
