The York University Libraries upgration project identifies collections that cover the range of object models that the repository uses. The conservative goal is to perform an upgration on the collections listed below. The stretch goal is an upgration all of all objects in the repository.

By upgration, we mean upgrating and migrating objects and datastreams, along with security restrictions (XACML), in Fedora 3.8.0 to Fedora 4.x. Moreover, we will develop a strategy for upgrading and migrating our content models, including inline XML datastreams, managed datastreams, and external datastreams.

York University Digital Library (YUDL) is an Islandora repository that run on the HEAD version of all Islandora Foundation modules. The repository is run as close a stock/generic Islandora instance where possible. Therefore, this upgration pilot can serve as a basis for a generic Islandora Fedora 3.x to Fedora 4.x upgration.
