Identifying discrete objects using the dnid scheme

I've been working with Sebastian Heath at the American Numismatic Society on a scheme for referring to discrete objects with unique identifiers.
The fundamental idea is very simple. Since internet domain names already provide a means of uniquely identifying a namespace (think of XML namespaces), we can apply domain names as qualifiers to ensure the uniqueness of existing, stable IDs for many kinds of materials that humanists cite.
I'll have more to post on this topic in the future, but for now, you can see where we're headed at http://www.dnid-community.org.
