| Summary: | 博士 === 國立交通大學 === 資訊管理研究所 === 97 === Internet libraries have been gradually popular in recent years. The appearances of “Free Content” and “Open Content” actually affect the amounts of Internet libraries materials. However, copyright is one of the most important issues of construction of a successful Internet library. In fact, how to legally collecting works in an economic way is a great challenge for librarians. Launching software robots to automatically acquire works on the Internet is efficient but with high potential legal risks, because the robots can not automatically comprehend the real copyright authorization scope. As a result, the libraries distribute or reproduce the collected works may infringe the copyrights of authors. To solve this problem, an ideal solution is designing a scheme which can be identified by software robots and can be used to fully express copyright authorization scope.
In this thesis, we propose two mechanisms which both fulfill the two requirements above: one is an expansion of the Creative Commons license, the CCFE, and another is a revised edition of the Robots.txt and Robots Meta tags. The CCFE can reduce one of the main disadvantages of the original CC: machine-readable metadata can not be easily embedded in digital files. In addition, with some extra commands and tags, the Robots.txt and Robots Meta tags can also be used to express copyright authorization scope as well.
