Will the Real Universal File Format please Stand Up?"
Sam Hiser, Gary Edwards & marbux
Abstract: This article compares the two solutions that are currently competing to become the universal file format standard: ODF (OpenDocument Format), from the OpenDocument Foundation, and EOOXML (ECMA Office Open XML) from Microsoft. The article analyses the two XML-based formats both from a technical point of view and in terms of their future impact on enterprises, focusing on their true interoperability and their ability to achieve maximum fidelity in the conversion of legacy files.
