Since the very first SWORD project, there have been two demonstration SWORD servers provided. These were funded by the original SWORD project. They have been in existence for a number of years, and have served as excellent demonstration servers for SWORD clients. However, they have now had to be retired.
http://dspace.swordapp.org/ used to provide a demonstration DSpace system. Instead, it is possible (thanks to Duraspace for making this available) to use the http://demo.dspace.org/ server. http://fedora.swordapp.org/ has not been replaced, but if anyone knows of a public test instance of Fedora that could be used, we’d be happy to update this page.
