OmegaWiki is self-described as a "collaborative project to produce a free, multilingual resource in every language, with lexicological, terminological and thesaurus information." In other words, "information on all words of all languages," a multi-lingual dictionary whose entries have definitions translated to as many languages as possible and which provides synonyms and translations for the word in even more languages. Significantly, the Omegawiki data is available in a relational database, making it is possible to use the wiki's data for many purposes.
As of March 29, 2009, Omegawiki had portals in 292 languages, representing the theoretical number of languages a word could be defined in. In its paging structure, Omegawiki differentiates between ''expressions'' and ''defined meanings'' (which correspond in a printed dictionaty dictionary roughly to entries or words and to numbered definitions). The number of expressions in various languages is [http://www.omegawiki.org/extensions/Wikidata/util/stats.php readily accessed] at Omegawiki page. The most recent check of this information showed 10 languages with more than 10,000 expressions, another 54 languages with 500 or more expressions, 105 with fewer than that but still more than five expressions, and 64 languages with five or fewer expressions.:
