An open file format is a published specification for storing digital data, usually maintained by a standards organization, which can therefore be used and implemented by anyone. For example, an open format can be implementable by both proprietary and free and open source software, using the typical software licenses used by each. In contrast to open formats, closed formats are considered trade secrets. Open formats are also called free file formats if they are not encumbered by any copyrights, patents, trademarks or other restrictions (for example, if they are in the public domain) so that anyone may use it at no monetary cost for any desired purpose.
Famous quotes containing the word open:
“Outside the open window
The morning air is all awash with angels.
Some are in bed-sheets, some are in blouses,
Some are in smocks: but truly there they are.”
—Richard Wilbur (b. 1921)
