We present an archive system named "Adria", which have been developed and maintained by ALMA project team of National Astronomical Observatory of Japan (NAOJ). Adria aims to store and open to the public various science data. Adria is composed of an object storage to store the observation data, the access control by "ticket", JSON format metadata, JavaScript APIs and html documents. The combination has the advantages of flexibility and solidity, which are important to store various telescope data in the same platform and to be maintained with small cost for a long time. Firstly, we have applied Adria to the observation data (since July 2013) of Nobeyama Radio Observatory (NRO) 45m, and then we have added the data (since June 2019) of Atacama Submillimeter Telescope Experiment (ASTE) to the same platform.
The current status of IRIS imager at NAOJ is reported. IRIS (Infrared Imaging Spectrograph) is a first light instrument of TMT (Thirty Meter Telescope). IRIS has just passed the preliminary design review and moved forward to the final design phase. In this paper, optical and mechanical design of IRIS imager and prototyping activities conducted during the preliminary design phase are summarized.
