RFXFreeze: A non-queriable compressor for RFX storage structure

XML has gained wide popularity for specifying and exchanging data on the WWW. XML is also used to store large amounts of bibliographic and scientific data. However, XML is by nature verbose and this contributes to the fact that XML databases are much large in size, thus increasing the cost for storing and retrieving data in smaller handheld devices which do not have large memory capacity. In order to address this problem, many XML-specific compression systems, such as XMill, XGrind, XQueC, XMLPPM, etc, have been developed. Recently, a work on storing the XML compactly has been developed, which proposes a non-tree based structure called RFX (redundancy free XML). In this paper, we propose a non-queriable compressor for the existing RFX structure which attains a high compression ratio at the cost of time for efficient retrieval of data.
