This book constitutes the thoroughly refereed post-proceedings of the Second International Conference on Topic Map Research and Applications, TMRA 2006, held in Leipzig, Germany in October 2006. The 15 revised full papers and 6 revised short papers presented together with 1 invited lecture were carefully selected during two rounds of reviewing and improvement from a total of 52 submissions. The papers are organized in topical sections headed creation and visualization of topic maps, applied topic maps in industry, administration and sciences, standards related research, leveraging the semantics, technical issues of topic mapping, and social software with topic maps.
