The Sustainable Protection of Intangible Cultural Heritage Information in Digital Era

The traditional approach has been insufficient to support the huge burden of the cultural heritage preservation and maintenance. Lots of intangible cultural heritage would disappear. In web time, Modern digital technology and network technology enhanced the protection efforts and efficiency of cultural heritage. With the popularity of digital protection methods, there were increasingly difficulties, such as the lack of funding and concept for post-maintenance; the dynamic changes in the environment, the complex format of digital file, the lack of public support and the problem of information management brought by intellectual property rights. With the current technological level and financial support, if wanted to achieve the sustainable development of digital preservation of cultural heritage, we should establish evaluation criteria on information as soon as possible and emphasize on the collaborative conservation and hybrid protection for the pursuit of cost-effective optimization, try to maintain a relatively stable environment of protection at the same time, vigorously promote the significance of digital protection, avoid or reduce the information loss and waste of resources in the process of refreshing information and avoid dilemma of using information.
