I've been trying to find some information on what kind of workflows are out there for metadata creation. Let me tell you, it is harder than you think. But I did stumble across a new piece of software that will hopefully be coming out soon: Rutger Libraries' Workflow Management System (inventive title, no?). Code4Lib did an article about it awhile ago, so it's not like super-new news, but I've noticed that not everyone and their mom reads Code4Lib. No offense to the C4L guys--you all seem quite awesome.
Anyway Grace Agnew and Yang Yu wrote an article about it, and it's pretty interesting stuff. WMS is really just like Archon or Archivists Toolkit, except that it's for anyone that's creating metadata, not just archives. I like that aspect very much, since here at our instiution, most of the digitization projects are actually hybrid projects that use staff from archives, the library, and the digital people. I imagine it's probably at least a little more user-friendly than the archives software, mostly because of who created it. Archivists can be....not so user-centered sometimes. Again, no offense (I'm offending lots of people today!).
