 **Q:** Explain the difference between an URI and a URL. (context: sample URIs look a lot like a URL.  What makes it a URI?)
 
-**A:** The distinctions among URIs (Uniform Resource Identifiers), URLs (Uniform Resource Locators), and URNs (Uniform Resource Names), relate to differentiating the functionalities of *identifying* a Resource, as opposed to *locating* a Resource, or doing both. URLs are all URIs (with some edge case exceptions subject to argument), and URNs are also URIs.  In many cases, URIs serve both to name and locate a Resource.  Within the vision of the Semantic Web, URIs are ideally unique, persistent URNs identifying some Web Resource, that can also serve to locate and retrieve (dereference) a representation of that Resource (URLs). The formal specification for these terms and what they mean is found in the Internet Engineering Task Force's (IETF's) *Request for Comments* RFC 3986, section 1.1.3 (<https://tools.ietf.org/html/rfc3986#section-1.1.3>). Another acronym one may encounter with increasing frequency is IRI (Internationalized Resource Identifier) that simply extends the concept of a URI to include full Unicode character set, rather than just ASCII in its construction (<https://tools.ietf.org/html/rfc3987>)
