OmegaWiki

OmegaWiki was a free, collaborative, multilingual dictionary project that aimed to describe words from all languages with definitions in all languages. It operated as a relational databased dictionary built on MediaWiki with a concept-focused model (DefinedMeaning) rather than being centered on individual words (Expressions). The project collected data at OmegaWiki.org and carried a history of development and collaboration among contributors such as Gerard Meijssen, Erik Möller, and Sabine Cretella. In later years, OmegaWiki’s status is described as defunct or inactive in Wikimedia-related references, with its data and history documented on Meta-Wiki and related Wikimedia pages.
