Identifier

(What is the attribute that identifies this thing?)

Characteristic

(what is the size, composition of the identifier?)

Universally Unique

(is this identifier unique across the domain in which it is used?)

Locally Unique

(is the identifier unique within a local domain such as a communication hub?)

Mutable

(can the identifier be changed?)

Transferable

(can the identifier be transferred to another thing?)

Discover-able

(does the thing provide a way to find the identifier by query?)

Relation to Owner

(does the identifier have a relationship with the owner?)

Applicability

(what is the industry, vertical, or other describer of the domain in which this applies?)

Secure

(is the identifier stored in a secure element or location?)

Controlling Body

(is there a formal body that controls the format and use of the identifier in the domain?)

URIs are a standard for identifying documents using a short string of numbers, letters, and symbols. They are defined by RFC 3986 - Uniform Resource Identifier (URI): Generic Syntax. URLs, URNs, and URCs are all types of URI. There are a number is URI schemes outlined at http://www.iana.org/assignments/uri-schemes/uri-schemes.xhtml
