Development of DIAS Metadata System

We are developing a metadata system in the Data Integration and Analysis System (DIAS) project sponsored by Japan Ministry of Education, Culture, Sports, Science and Technology. A major goal of the DIAS metadata system is to collect all metadata of earth observation data produced under the projects sponsored by Japanese government. The DIAS metadata system is comprised of metadata registration system, metadata retrieval system, and download system.Cooperation with other data centers is also an important goal of the DIAS metadata system. We have imported metadata from JAMSTEC (Japan Agency for Marine-Earth Science and Technology) data catalog and JaLTER (Japan Long Term Ecological Research Network) database, and supported integrated metadata search through the DIAS retrieval system. On the other hand, by exporting DIAS metadata, DIAS is now listed in the Earth Observation Catalogs of GEOSS Portal. We are developing a metadata coordination system to make it possible more comprehensive exchange of metadata among data centers.

The international society is increasingly agreeing with the idea of sharing scientific data openly between society and scientists, as stated in "The Future We Want" at RIO+20 2012, and the Open Data Charter agreed by G8 in UK June 2013. Data is also one of the most important multidisciplinary issues for JpGU. Significant research areas in The Union stand on research data which are substantially important in its sciences and cannot be obtained and/or be produced again. In international context, ICSU-WDS (World Data System) is proceeding for goals of open data sharing and long term preservation. DIAS (Data Integration and Analysis System) is under development as Japanese contribution to GEO/GEOSS. New actions are starting including Future Earth, re-forming global environmental science enterprises, and also Belmont Forum's discussion of e-infrastructure development whose targets include a support of Future Earth's data activity. Furthermore academic publishers like Thomson-Reuters and WDS started collaboration for data publication and data citation (use e.g. DOI or Digital Object Identifiers attached to datasets for citation in scientific articles). Discussions and exchanges of ideas, difficulties and challenges will be covered for future international data framework.
