The URI microformat takes advantage of OpenURL and existing link resolver solution.It defines a convention of plugging URI metadata in HTML page. If it is adopted and widely used,now a microformat-aware application (be a greasemonkey script, or a web service) can grab the identifier and point to your local OpenURL resolver, you immediately get the copy from local library. It is very similar to COINS, but it's much simpler and cleaner, anyone can understand and use it, and its aplication can be beyond traditional research library. e.g. in a public library, you can use amazon as catalog and immediately check if it's available in local collection. COinS provides a great number of additional capabilities that URI microformat can't support. Since COinS can't be dismissed for this reason, it doesn't make sense to me to create yet another standard that does the same thing with so little savings.I will grant that the COinS is less intuitive.....
