The consideration of the interoperability of an institutional repository, both with existing systems and potentially with future systems and other digital libraries, is a valid one. It will not serve us to waste our time and effort on a system with no future; and if we invite the academic community to commit their time and valuable resources to our repository, it would behoove us to be able to maintain the availability of their materials throughout future developments. We cannot afford to offend and disillusion our contributors.
