Open Document Format

Open Document file standard was proposed in 2005 by a technical committee in the Organization for the Advancement of Structured Information Standards (OASIS) consortium. Open Document Format (ODF) is based on XML specification. Originally it was developed for Sun StarOffice as an open standard for office documents.

Open Document file format uses XML to describe its structure and store content. This makes it easier for developers and users to view how this document is stored and make changes just by using text edit.

ZIP compression is used to compress Open Document files. Since XML is a text format, ZIP is very efficient in compressing it.

Open Document Format is supported by several software packages. Some of the most popular ones are:

  • Microsoft Office (supports certain ODF features depending on the version)
  • OpenOffice (free software)
  • TextEdit editor for Mac OS
  • LibreOffice (free software)
  • Calligra Office Suite by KDE

Following file extensions are used by files in Open Document format:

  • ODT and FODT for word processing files
  • ODS and FODS for spreadsheet files
  • ODG and FODG for graphics files
  • ODP and FODP for presentation files
  • ODF for formulas and equations
