Good news for Japanese Semantic Web researchers or Japanese people interested in the Semantic Web. Seiji Koide from the National Institute of Informatics, Tokyo has translated the entire W3C RDF semantics specification, which is the one of the foundations of Semantic Web, into Japanese! It is available at the following link.
This would be a great contribution for the Japanese people having a hard time trying to understand the specifications in English. It is even harder to translate and use those terminologies properly while doing research in Japanese and explaining them to the Japanese communities. Great job ;-)
