About physical hyperlinks and web/id (see also Cooltown)
The term internet of things has arisen in the past couple of years, for what in the Cooltown project we termed the Real World Wide Web: the systematic linkage from physical entities to web resources. We should have used Physical World Wide Web, but that didn't sound as good! A related term we used was physical hyperlink. Sometimes physical hyperlinks take the form of URLs physically bound to the physical entities &mdash for example, in the form of a Cooltown beacon that broadcasts the entity's URL to handheld devices nearby. But other times entities bear identifiers rather than URLs. web/id is the system that resolves identifiers such as tag URIs printed on or attached to physical entities, in order to link them to web resources.

- Tag URIs (RFC 4151, Tim Kindberg and Sandro Hawke) &mdash a new type of URI that enables anyone who currently holds an email address or a domain name to construct a resource identifier that is unique for all time. This page has a unique tag URI at the end and in the title. You can find this page via a search engine from its tag. It turns out Leslie Lamport had a similar idea - see his "Archival References to Web Pages".
