Institutions And Practical Research On The Long-Term Preservation For The Periodical Resource Of Open Access

Open access as a new and free scholarly electronic resource, promoting shared vision of academic and publishing mechanism, is concerned and supported by various academics. In order to make the open access periodical resources effective and permanent, the long-term preservation of digital resources which introduced into the the movement of open access effectively promote the development of open access. The long-term preservation which based on the periodical resource of open access has become a hot research direction of this field. Even somebody thinks that the long-term preservation of digital resources is the key to the success of the development of open access. The emergence of long-term preservation of the open access periodical resources will promote further the development of open access movement and avoid the losses caused by the loss of open access periodical resources caused by uncontrollable factors.Firstly, this paper describes the cooperation model, the accountability system, preservation mode, technology strategy and OAIS model of the long-term preservation of digital resources which has been appeared. Secondly, it analyses simply the current situation of the open access movement and highlights the OAI protocol and access platform of open access periodical. Lastly, it comes up with the problems now of open access periodical resources’long-term preservation on the basis of the above-mentioned:there has not been a architecture of open access periodical resources’long-term preservation; there has not been a long-term and accessible mechanisms which replace the work of manual data acquisition in the process of resource database’s construction.In response to these problems, the author has been built the frame of open access periodical resources’long-term preservation by analyzing the process of the changing role of the responsible for long-term preservation and the changing of long-term preservation mode and save accountability system. The frame which includes periodical resource database, access mechanism of resource, access platform based on resource, the corresponding interface providing access to local resources for remote off-site public platform which is achieved by OAI protocol and so on is based on OAIS model and is supported by cooperative model, accountability system and save model.On the basis of the architecture of open access periodical resources’long-term preservation, the author constructs the mechanism to access the metadata of resource library by analyzing the fault of access platform with no steady source of data which has been finished by Shumei Zhu. In the last, the author has achieved the long-term accessibility of more than70kinds of agriculture-related open access periodical and obtained the results of the implementation of access mechanism. There is a small number error in the final data results. But the way to download is better than the manual. The date is just updated regularly by the relevant officers.However, the perfection and maturation of the architecture of open access periodical resources’long-term preservation need to be further studied. In this paper, the author has not finished the corresponding interface providing access to local resources for remote off-site public platform which is to be achieved.
