This volume constitutes the selected papers of the 5th International Conference on Metadata and Semantic Research, MTSR 2011, held in Izmir, Turkey, in October 2011. The 36 full papers presented together with 16 short papers and project reports were carefully reviewed and selected from 118 submissions. The papers are organized in topical sections on Tracks on Metadata and Semantics for Open Access Repositories and Infrastructures, Metadata and Semantics for Learning Infrastructures, Metadata and Semantics for Cultural Collections and Applications, Metadata and Semantics for Agriculture, Food and Environment.

This unique collection examines the man Utne Reader has called "the greatest social critic of the twentieth century." The essays—all by people Illich has influenced personally—discuss how his life and thought have affected conceptualization, study, and practice of psychotherapy, notions about education, ideas concerning the historical development of the text, perceptions of technology, as well as other topics. All of Illich's books are discussed and his ideas on education, theology, technology, anarchism, and society are examined in relationship to those of René Girard, Karl Polanyi, Emmanuel Levinas, and Jacques Ellul. Illich's previously unpublished paper offering a new view of conspiracy in European history is included.
