UD, like many other research universities, is beginning to consider the need for geospatial data repository resources. In some cases the best repository may be cloud-based, and in others, local.
Here are some links that may be useful, if you are considering geospatial data preservation, both to the end user and to UD research resource staff.

DSpace Futures (this alludes to the fact that is a future feature set, also MANAKIN is a DSpace project that seems to move towards this goal)
