# Introduction
With the fundamental problems of open data and data sharing which are huge handle to many researchers and research communities, it is therefore in need of bringing those issues on the table for APAN community to discuss and find out possible solutions together. In this working group, good practices will be shared, obstacles and standards will be presented and discussed toward feasible suggestions and solutions. Of course, those issues are not easy to solve, but toward sustainable development, climate change mitigation, adaptation and resilience, we need to over come those and find a common ground together to open as possible and to close as necessary.
