Syntactical Compression of XML Data

One of the most palpable drawbacks of XML can be seen in its excessive storage requirements. In this paper, we address this problem by proposing a syntactical XML compression scheme which makes use of probabilistic modeling of XML structure. Our compression scheme works sequentially and makes on-line processing of the data possible. We describe the current state of development of the prototype compressor and present some preliminary performance evaluation results. The compressor is designed to be extensible, and intended to serve as a platform for further research in the field of syntactical XML data compression.
