Digital Rights Management metadata is introduced in the paper, ODRL and MPEG-21/5, the two most popular DRM metadata, are also explored. Besides, the applications of DRM metadata in digital libraries are analyzed based on the research. The paper argues that, the DRM metadata, which is originally used in the Electronic Business area, can not yet satisfied the demand of digital libraries in contemporary phases.
XrML is a right expression language which based on XML. It describes the relative right, condition and so on when you are using a digital works. XrML currently has become an international standard and is getting more and more popular. This paper designs and implements an XrML validator, and it can be called directly by those systems which need the functionality of DRM. The advantage of this validator is that it’s developed using C++, so it’s very compact and can be used in such fields as embedded system.

This paper proposes a formal framework model for the intelligent information retrieval. It outlines the typical modeling method, knowledge representation and retrieval algorithm for instantiation of the given formal framework. It provides the statistic analysis of the modeling framework, knowledge representation and retrieval algorithm for 30 intelligent retrieval systems. It summarizes three kinds of solutions for instantiation of the formal intelligent retrieval model.
Binarization is one of the chief technology in digital image processing in library, The quality of the digital books lie on the result of the binarization. This paper introduces a new whole binarization method by using image gray statistical characteristic value as threshold. In the course of the text image processing, the algorithm can automatically realize the threshold segmentation by using the characters of the high-low pass filter based on the histograms of distinct text images. The algorithm has lower time complexity and space complexity, and has been applied in one digital library system.
Scirus is a kind of scientific search engine which aims at scientific or special information. It helps people to find what they need exactly from a great deal of information quickly and correctly. It works well, and won the honor of “the best specialty search engine” of SearchEngineWatch for three years. The paper gives an introduction to Scirus. We try to find out how Scirus could “pinpoint results” on the base of “SCIRUS White Paper: How Scirus Works”.
