We are exploring omeka and so far like it. We currently have a dspace server, and would like to harvest from there to omeka. I installed the harvester plugin and was able to use it to harvest the test set (http://vagovernmentmatters.org/oai-pmh-repository/request) with no problems. However, when I try to harvest from our dspace server, I get "String could not be parsed as XML". Our URL is http://dspace.willardlibrary.org/oai. When I do http://dspace.willardlibrary.org/oai/request?verb=ListSets, it seems to look fine to me. What am I missing?
