 So, my name is Jingbo. I'm the data manager at National Computational Infrastructure. To address the data accessibility, I'm going to talk about the legal social aspect about how to control the data access. Also, I'm going to present the persistent identified implementation to manage persistently access the data. Then I'm going to address how do we provide the data through various types of data services, OGC standards, and eventually I'm going to touch base simply about data version and our quality. Thank you very much.
