With the rapid growth of information technology and the internet. the physical contents are transformed into digital contents at a fast rate. With the change. accessing the digital contents, toe service methods and the identifier used for the digital contents are not systematic and limited for use. The DOI identifier system used for the URN is also limited to academic journals or magazines and are not adequately applicable for non-academic journal or digital contents. Therefore. we have developed a unique identifier based on the analysis made on the system adopted by foreign digital contents service institutes. two types of academic journals 3 types of non-academic journals owned by KISTI that can be adopted by non-academic journals. The identifier is to be used to design and implement a digital contents service system.

Upon the growing popularity of knowledge information and paid digital content, the Internet knowledge exchange market had emerged. A Internet knowledge exchange market consists of general characteristics of a market where a wide variety of knowledge is exchanged at market-appropriate prices, the Internet knowledge exchange market is recently gaining momentum with specialized knowledge items such as design, program source, patent information, consulting service, multimedia, or resumes, as it seeks to secure competitive advantage over its peer markets. Considering the immense influence that these Internet markets will exert on the existing system of knowledge circulation including libraries and information centers, this study aims to contribute to a better understanding of Korea's knowledge circulation structure by analyzing the current standing of the Internet knowledge exchange market.

Despite the fact that the mobile environment has favorable conditions for using data contents, it is not easy to implement enhanced data services for mobile broadcasting based on MPEG-4 BIFS. With a structure inherited from VRML, BIFS targets different types of content with a development approach that is not very compatible with broadcasting contents. Furthermore, it is not easy to implement BIFS because the standard is too complicated for the mobile broadcasting environment. Accordingly, this study proposes an enhanced mobile TV contents model that provides interactive 3D objects and GUI for the viewers to interact with the broadcasting contents. By applying the model to the DMB environment, this study suggests a direction for future developments of mobile broadcasting contents. In order to represent 3D graphics on mobile TV, we analyzed MPEG-BIFS 3D nodes and composed a subset of VRML profile, and defined new nodes that can efficiently represent GUI at the content development level. If this study helps facilitate expression of 3D graphics and interactions in data contents composition, enhanced efficiency of contents development is expected to promote the development of various contents suitable for the mobile broadcasting environment.
