Comparison of Wordprocessing Document Format in OOXML and ODF

OOXML (Office Open XML) and ODF (Open Document Format) are the world's two major document format standards. The structure and some main components of the word processing document in OOXML and ODF are analysed and compared in detail. The results are the base of document interoperability between OOXML and ODF. Some valuable conclusions can be gotten that 1) Most components of the word processing document in one format have the logical counterpart in the other one, 2) Some components have no counterpart or some corresponding relationships between OOXML and ODF are very complicated. The latter point is one of the most important obstructions in the interoperability between OOXML and ODF.
