Hi Robin, Again I had the same problem to specify the different metadata for different document types within one collection. I'd say this is the limitation of DSpace that doesn't allow you to do so. In my project, we need to handle six different document types, conference paper, journal articles, book, book chapter, working paper and thesis & dissertation. In our special case - a small organization with only one collection but multiple document types, I decided to represent collections as document types so that from end user's view, it looks like they are submitting different document types to one collection, but at the back end, the documents actually have been organized into different collections. This way, you can specify different metadata for different document types in collection level. However, if you want to preserve the collection use, this maybe not a feasible way. Or if your client doesn't mind, just define each document type as a collection (my client doesn't like this idea). The other way around? My investigation was a lot of work needs to be done on DSpace.
