It is important for an office suite to use standards where possible, especially for the file format. The OASIS OpenDocument file format specification is an open standard for office applications. This format is spreading more and more, it is also the same file format OpenOffice.org uses, which means that file exchange with any user of this office suite is easily possible.

Adhering to official standards is always a good thing. For business environments it is even vital to exactly know about their documents.

KOffice has more components to offer than what is covered by the OASIS specification. Still, all components covered by the specifications actually use the OASIS OpenDocument file format.
