Research On Open Access Policies Of Astronomical Science Data And The Popular Science Education Based On Scientific Data

Astronomy in the new century is stepping into a data- intensive and data-driven era. Data-intensive scientific discovery becomes the forth paradigm for modern scientific research. With the continuous development of the economy in China, astronomical community and facilities are under fast developing. Data resources from Chinese astronomical projects and facilities are just at the starting point of explosive growth. It is crucial for the long-term development of Astronomy in China to build an open data access environment.First, this paper investigates open data access laws and policies of different governments and international organizations. Following the principle of "full and open access to data". Policies and rules about astronomical observation data of various astronomical projects, telescopes and data centers are introduced. Several related aspects, including data resource specifications, priority period, archiving rules, publication policies, data citation and acknowledgment, are sMajor astronomical datasets from telescopes and research projects in China and their open data access situation are discussed in the second part of the paper. Difficulties and challenges facing astronomers in China to provide full and open data access for astronomical data archives are summarized.Six specific recommendations to improve open data access are suggested, including definition and improvement of laws and specifications on open data access, establishment of effective management framework on astronomical data archiving and access in governments and institutes, building astronomical data center(s) for the nation or for the whole community, research on key technologies covering full astronomical data lifecycle (creating-processing-analyzing-preserving-giving access-using), training data scientists and data engineers, popularization of data archives and scientific data based applications.Perfect astronomical data sharing policies can promote the effective use of scientific data, the positive role of the scientific data in astronomy research and education, will supervise and promote the development of the science data of astronomy open and sharing policies, they are promote each other, complement each other.WWT software is a good crystallinity of astronomical data sharing policy. The WWT integrate the world’s best astronomy data resources for seamless transparent, promotes the development of popular science education in national astronomy. In this paper introduces some work and achievements in science education based on the scientific data, and analysis, sums up the experiences. Focuses on the construction of astronomical curriculum system of elementary and middle schools based on the WWT, WWT- based astronomy teaching practices, as well as traditional Chinese stars three of WWT integration and sharing of data resources. According to practice, we know that the advantage of science education based on the scientific data in WWT platform is mainly reflected in its interactive, collaborative, exploratory and situational. In short, in the era of big data, science education based on the scientific data in response to the reform of educational information, and promotes domestic science education reform and innovation.
