Hear, hear. Having correct, complete machine-readable metadata in the document itself is a Good Thing. Researcher: if you do this yourself, it's in your interest to ensure that you do it well. If you have an assistant to take care of such things, it's in your interest to ensure that your assistant knows how to do it well. If you depend on Google Scholar or something like it, you (all) get out of it what you (all) put into it. The notion of a repository doing this automatically, whether machine-readably or by generated cover pages, leads to some interesting corner cases. If the title page, repo. metadata, and document metadata disagree, which one is correct? If the document contains poor-quality metadata, but it does contain them, then should the repo. *replace* them with corrected values? On the other end of the ingestion process, what if we *extract* metadata from the document and then have to correct them? do we fix the document? And regardless of how much we trust our own process, will search engines trust our repo., the document metadata, or their own heuristic fishing in the first page? To gather some ideas, we might want to see what commercial publishers do about these issues. (Oh, boy: what if an academic repo. and a publisher make *different* adjustments to document metadata? Can we get repo.s, publishers, and researchers to agree on priorities and a process for polishing and harmonizing document metadata?) I think that, in the end, all parties want "the best we can reasonably do." But how do we get there? -- Mark H.
