Abstract :
This demonstration presents a GML specific compressor that exploits the unique characteristics of GML documents to achieve better compression performance than the existing XML compressors. We call this compressor GPress, an abbreviation of "GML comPressor". To the best of our knowledge, GPress is the first compressor developed specifically for GML documents. Experimental results show that GPress outperforms the best existing XML compressor XMill evidently in compression ratio.
