A Perspective from Digital Preservation on Sustainability of E-Infrastructures 
Much effort is expended on assuring sustainability of e-infrastructures and the services within them. Some of these services have a dimension of long-term preservation, in particular the infrastructure around persistent identifiers (PIDs). It is therefore worth asking whether established approaches to long-term digital preservation can offer insights into planning for sustainability. This paper examines some aspects of the OAIS Reference Model and their applicability to sustainability planning for e-infrastructures.
