The W3C is jointly hosted by the Massachusetts Institute of Technology Laboratory for Computer Science [MIT/LCS] in the United States; the Institut National de Recherche en Informatique et en Automatique [INRIA] in Europe; and the Keio University Shonan Fujisawa Campus in Japan.Massachusetts Institute of Technology Laboratory for Computer ScienceInstitut National de Recherche en Informatique et en AutomatiqueKeio University
