Hi Charles,
Just to follow-up on James' comment, and perhaps speak more directly to the kind of functionality you're describing, would it be reasonable to suggest a function wherein, when editing an article's metadata (either in submission or editing), an author/editor could search the system for additional authors based on email address (as suggested in the thread James references)? This would provide limited access to the user database, but in instances where: a) the submitting author knows the email addresses of additional authors; and b) those authors are registered in the OJS system under the same email addresses, it would simplify editing somewhat.
I should also add that the issue of managing author metadata, and unique identity / name authority, is a much larger and very common problem in the world of scholarly publishing in general -- and there are a number of efforts underway by various publishers and organizations to attempt to address via author IDs, etc. Martin Fenner has some interesting discussion of these on his blog (
http://network.nature.com/tags/authorid), although I can't see us supporting author IDs within OJS any time in the near future, at least until they're well-established and many of the existing concerns have been addressed.
Hope this helps,
MJ
