Standardization of massive data from various telescopes at Xinglong Observatory

Abstract

Xinglong Observatory of the National Astronomical Observatories, Chinese Academy of Sciences (NAOC) has accumulated various and massive observational data, and new data are continuously being generated. However, an archive to effectively manage these data has not been established. We plan to create a data archive system designated as the Xinglong Data Sharing Platform (XDSP). The bottleneck for creating the XDSP is the collection of metadata, which are mainly derived from the FITS (Flexible Image Transport System) headers. To overcome this bottleneck, we have established a Xinglong Observatory Public FITS Header Standard (XPFHS). We then created flexible Information Acquisition Software (IAS) for collecting metadata according to the XPFHS. Based our successful collection of metadata, we built an XDSP test version, and we popularized and applied the standard XPFHS and the IAS tool to other observatories.
