  Data sharing is essential in the numerical simulations research. We introduce
a data repository, DataVault, that is designed for data sharing, search and
analysis. A comparative study of existing repositories is performed to analyze
features that are critical to a data repository. We describe the architecture,
workflow, and deployment of DataVault, and provide three use-case scenarios for
different communities to facilitate the use and application of DataVault.
Potential features are proposed and we outline the future development for these
features.
