The OpenTaal project (Dutch for “OpenLanguage”) has published the first open source word list to be certified by the Dutch Language Union as corresponding to official spelling. Simon Brouwer, project leader of OpenTaal, says, “This is a milestone. Users of open source software can trust their Dutch spell checker now. They have the guarantee that their word list is consistent with the official spelling.”
Other products that have received certification include Microsoft’s spell checker and the dictionaries of publishers Sdu, Spectrum, Van Dale, and Wolters Plantyn.
