Developing a Repository Lifecycle Model and Metadata Description: Modeling and Describing Changes

In the past decade a wealth of data repositories and open datasets across all disciplines have been created. Registries of repositories have also been established, mostly by discipline (medical, social sciences) or by ownership (academic, governmental).nbsp; We have reached a point where a lifecycle model should be constructed for these resources, as well as a set of agreed-upon metadata to describe them. We will present our repository lifecycle model, and propose the most likely existing metadata schemas for constructing an overall description for repositories.
