We've been twitting new resources for a while now at @ubcnewbooks and I
added annotations when the topic came up last time. Until just now the
annotation was:

{
	subject:	"LC subject",
	isbn:		"ISBN13",
	call_number:	"(local) call number",
	author:		"Author",
	title:		"Title",
	alternate_title:"(from MARC 880 if available)",

// And since just now I've added these to closer align with the
recommendations:

	type:		"book|ebook|music|map|video|...",
	year:		"20xx",
	url:		"http://url.of.ebook/if_available"
}

It's hardly MARC, but it's something. One thing I haven't decided is
whether the 'url' should point to the item's catalog record or to the
ebook url, since the catalog url is in the actual tweet.
