Research in science and technology fields today generates large quantities of data. This data not only needs to be processed and analyzed, it needs to be managed.
Funding agencies such as the NSF now require Data Management Plans to be submitted with grant proposals. These plans must explain how the researcher plans to manage the data generated by the research, addressing issues like security, version control, documentation, ownership and access, preservation, and sharing. If long term preservation and sharing is desired, the researcher must choose an appropriate repository to host it.
