So, move author into ascii? Most 30040s won't be cohesive documents, like an original book, but rather someone's personal compilation of  documents or snippets. A sort of remix. They won't have an author, but the 30041s might and they'd probably have author in the ascii or the form would get really messy.

Right now, these are the mandatory tags (we need "d" and we need "title" to make "d"): 
	    [ "d", "<identifier>" ],
	    [ "title", "<full_index_title>" ]

And these are the optional ones:
	    [ "author", "<author_name>" ],
	    [ "i", "isbn:9780765382030" ],
	    [ "t", "<topics about which the event might be of relevance>"],
	    [ "published_on", "<date in the format YYYY-MM-DD>" ],
	    [ "published_by", "<publisher of the source material>"],
	    [ "image", "<URL pointing to an image to be shown with the title>" ],
	    [ "summary", "<human readable description of the work>" ],
	    [ "version", "<the volume, edition, or translation included>" ]
