An XML-based specification describing the content and formatting of a document. The open standard developed by a multi-vendor committee at OASIS and an ISO standard. The default document format in prominent office suites including OpenOffice.org, Google  Docs, IBM Lotus Symphony and IBM Productivity Tools in Notes 8. The option that gives the most choices for interoperability and future- proofing information.

The Challenge : Need of programming frameworks Programming the ODF as XML DOM elements requires mastery of ODF specification. There is need of an ODF API that exposes a higher level abstraction of ODF to application developers Odf4j in ODFToolkit intends to provide programming framework in Java  for creating and processing ODF document. Odf4j is still in early stages. Initial prototypes of ODF based emitter are based on Odf4j with added extensions.
