What is ODF, the OpenDocument Format?

• 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.

Why ODF SpreadSheet Emitter• Standardized XML file format : Provides control over documents

• Multi Platform Support - Supported on Windows, Linux and Mac

• Better interoperability : Separation of document from application Document can be processed by other applications

• Provides choice, freedom of action, cost effectiveness, access to innovation and greater control over the use of documents

• Once the data is in Spreadsheet, it can be manipulated using Spreadsheet functions/formula's.

ODF SpreadSheet Emitter for BIRT

• Implementation of ODS (Open Document Spreadsheet) custom BIRT emitter.

• Creates ODF Spread-Sheets from BIRT reports

• Prototype supports extraction of data and basic styles into spreadsheet.

• Work in progress to match original layout of the report and output images.

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.
