Conclusion & Future Direction
    Improving related laws and policy for efficient collections and
    preservation

    Developing and disseminating national standard models

    Apply and develop the standardization of metadata on the digital
    resources (DCMI, PREMIS, OAIS 14721, DCF-TTA ,..)

    Assigning a digital identification system to protect intellectual
    properties of the collected digital resources and to facilitate their
    distribution

    Researching & Developing the Digital Legal Deposit System

    Research of search technology for the copyright-cleared resources
    should be followed.
