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.
