The document discusses lessons learned from the Smithsonian Institution (SI) about using data management plans (DMPs) to meet internal data management needs. Specifically, it notes that SI requires DMPs at multiple levels, including for each museum/unit, intra- and extramural projects, and grant-funded research projects. It also emphasizes that DMPs should be living documents, have assessment potential, utilize APIs to share data, and be fluid enough to work in different locales. The overall lessons focus on applying a tiered, adaptable approach to DMPs tailored to an organization's unique structure and needs.
