Principle 2: WIS 2.0 uses Uniform Resource Locators (URL) to identify resources
BENEFIT:
URLs uniquely identify a resource and describe the primary mechanism for retrieving or interacting with it (i.e. the network 'location' and the communications protocol to be used).
[1] URL is a subtype of URI - see RFC 3986 URI generic syntax, §1.1.3. URI, URL, and URN https://tools.ietf.org/html/rfc3986#section-1.1.3
