After 3 years of specifying the UNL (Universal Networking Language) language and prototyping deconverters1 from more than 12 languages and enconverters for about 4, the UNL project has opened to the community by publishing the specifications (v2.0) of the UNL language, intended to encode the meaning of NL utterances as semantic hypergraphs and to be used as a "pivot" representation in multilingual information and communication systems. A UNL document is an html document with special tags to delimit the utterances and their rendering in UNL and in all natural languages currently handled. UNL can be viewed as the future "html of the linguistic content". It is only an interface format, leading as well to the reuse of existing NLP components as to the development of original tools in a variety of possible applications, from automatic rough enconversion for information retrieval and information gathering translation to partially interactive enconversion or deconversion for higher quality. We illustrate these points by describing an UNL-French deconverter organized as a specific "localizer" followed by a classical MT transfer and an existing generator.
