W3C announces today a Workshop on Linked Open Data and Multi­lingual­Web-LT Requirements, 11-13 June in Dublin, Ireland. Organized by the MultilingualWeb-LT Working Group, the purpose of this workshop is two-fold: first, to discuss the intersection between Linked Open Data and Multilingual Technologies, and second, to discuss Requirements of the W3C MultilingualWeb-LT Working Group. Participation is free. We welcome participation from both speakers and non-speaking attendees. However, whereas future MultilingualWeb workshops will continue the wide-ranging format of previous MultilingualWeb events, and will aim again at a larger audience, attendees for this workshop are required to participate actively in discussions and will need to submit a position statement for the workshop registration. There are limited spaces available. Learn more about Internationalization at W3C.
