We also have four production repositories: o One we provide as a general IR for publishing research materials from throughout the institution. o Another embodies the online portion of our university Archives (operational stuff: minutes, nonacademic publications, course catalogs, etc.) o The third is a special collection of materials on philanthropy, donated by various organizations. o The fourth we set up in a partnership with another organization to hold a collection of public-policy materials from all over. The first is the only application on its host, while the other three DSpace instances share an instance of Tomcat and the server that runs it. The repo.s have different focuses and different administrative policies, and it was thought best to keep them separated. I may say that the decision to split them up was made when we had less experience with DSpace, back in the 1.2 or 1.3 timeframe, and we might choose differently today. In fact the public-policy collection was taken in-house by our partner and we now only hold a dark-archive copy of the materials for disaster-tolerance, so it was good that that part of our operations was readily separable. We 'tar'ed up the assetstore, dumped the database, and sent those two files to them on a portable disk drive. This was a 1.4.2+Manakin instance and I can't clearly see how else we might practicably have disgorged 20,000 Items. It also had deep third-party customizations that would have made it quite difficult to share an instance with other collections. With 1.7's much improved facilities for bulk export of entire Communities and Collections, handing over a large collection like this would have been quite do-able without giving up the entire repo. So I find that argument less compelling today. -- Mark H. Wood, Lead System Programmer [email protected] Asking whether markets are efficient is like asking whether people are smart.
