In the present report, we show current status of mathematical journals in Japan. Because most of their electronic edition have been loaded on various digital repositories with support of OAI-PMH, we have been able to design a subject based portal website and visual user interface which consists of harvested metadata of the journals. The outline of the portal website is reported also.
In this paper the authors show an overview of Virtual Digital Mathematics Library in Japan (DML-JP), contents of which consist of metadata harvested from institutional repositories in Japan and digital repositories in the world. DML-JP is, in a sense, a subject specific repository which collaborate with various digital repositories. Beyond portal website, DML-JP provides subject-specific metadata through OAI-ORE. By the schema it is enabled that digital repositories can load the rich metadata which...
The exchange of preprints and journals plays an important role to communicate new research ideas and results in many academic fields. Distribution of preprints and journal articles by electronic file via the Internet has become a primary method in addition to paper publication. Electronic preprints and articles in the paperless era should be certified in terms of existence proof and tamper resistance because they are easily modified by their site administrator. We developed a secure preprint and...
