Comparative Research of XML Compression Technologies

Abstract

XML is a de-facto standard for exchanging and presenting information on the Web. However, XML data is also recognized as verbose since it heavily inflates the size of the data due to the repeated tags and structures. The data verbosity problem gives rise to many challenges of conventional query processing and data exchange. The hindrance is more apparent in bandwidth-and memory-limited devices. Compression techniques are the important way to overcome the verbosity problem. This paper compares and analyzes proposed the state-of-the-art XML-conscious compression technologies, study their pros and cons, then discuss further works.
