SPring-8 experimental Data Repository system (SP8DR) is an online storage service, which is built as one of the infrastructure services of SPring-8. SP8DR enables experimental user to obtain his experimental data, which was brought forth at SPring-8 beamline, on demand via the Internet. To make easy searching for required data-sets later, the system stored experimental data with meta-data such as experimental conditions. It is also useful to the post-experiment analysis process. As a framework for data management, we adopted DSpace that is widely used in the academic library information system. We made two kind of application software for registering an experimental data simply and quickly. These applications are used to record metadata-set to SP8DR database that has relations to experimental data on the storage system. This data management design allowed applications to high bandwidth data acquisition system. In this presentation, we report about the SPring-8 experimental Data Repository system that began operation in SPring-8 beamline.
