Abstract

Starting with Microsoft Office 2007, the Office Open XML file formats have become the default file format of Microsoft Office. As each day a lot of office documents have to be stored and transferred, reducing the document size will yield a benefit when storing and transferring these files. We present a compressed format for XML-based office documents that omits that data from an office document that is already defined by the Office Open XML format. Our evaluation shows that our compressed format reduces the – already compressed – office documents to a data size down to 41% of the original document size. Furthermore, for search operations tested in our evaluation, searching is faster on our compressed office documents than it is on the original documents.
