This manuscript does not provide the obvious contribution as a research paper. The author has proposed the"development" of web service system for the management of VDO content at the library. The interesting point might be the process improvement which the author does not go through in detail. Further more, the evaluation of the paper is not consistent with the proposed method.
As a consequence, the author should provide the principles of the process improvement. Is it what author invented? Or is it what other people invented? Why does the author choose this technique? Unless this question has been answered in the manuscript, the paper cannot be accepted.
