Discussion towards reliable and productive astronomical data archives

Astronomical data archives are recognized as an essential infrastructure for astronomical activities. They are also indispensable records of every single moment of the universe -- a heritage for the human beings. Despite the consensus on their importance, it has been a long-lasting issue to secure human and computing resources for maintaining and improving functionality of the data archives. Recently, the situation has been getting more challenging, as each community is required to accommodate forthcoming big projects within a limited budget frame. To overcome this difficult time, it is quite important to define solid missions of the data archives and consolidate efforts with commitments towards prioritized goals. Specifically in the Japanese community, we have started to investigate demands and optimal ways of operation for reliable and productive Optical-NIR data archives. Our objectives include to identify 1) what to archive, 2) necessary functions, and 3) roles of individual teams involved in data flow. The current discussion indicates importance of understanding achievements and strengths of the data archives, making data available to public, and defining responsibilities of both data providers and archivers. We aim at putting the results into a proposal of data management in the Japanese community. To learn situations in oversee archives, we also made an unofficial survey for several archive people. It seems that in the US and European archives, stably and successful achievements with archival data have convinced the local community, which leads to proper valuation and financial support. This poster describes the current outcomes from the ongoing discussion.
