UniformResourceIdentifiers

http://www.ietf.org/rfc/rfc2369.txt (RFC)

웹에서 리소스들을 구별하기 위한 간단한 문자열. 이것을 이용하여 문서와 다운로드할 파일들, 이미지들, 서비스들, 그리고 다른 공유된 정보의 리소스들을 구별한다.

예를들어

인터넷에서 논리적인 이름으로 영구정보를 식별하는데 URN을 사용한다.

The basic picture, specified in section 1.2. URI, URL, and URN of RFC 2396, looks like this:

         _______________________________________________________
        |         ________________                              |
        |        |  ftp:          |                             |
        |        |  gopher:       |                             |
        |        |  http:       __|____________                 |
        |        |  etc        |  |  urn:      |                |
        |        |_____________|__|            |                |
        |                URLs  |               |                |
        |                      |_______________|                |
        |                             URNs                      |
        |_______________________________________________________|
                               URIs
  • URI : Uniform Resource Identifier. The generic set of all names/addresses that are short strings that refer to resources.
  • URL : Uniform Resource Locator. An informal term (no longer used in technical specifications) associated with popular URI schemes: http, ftp, mailto, etc.

  • URN : Uniform Resource Name.
    1. An URI that has an institutional commitment to persistence, availability, etc. Note that this sort of URI may also be a URL. See, for example, PURLs.
    2. A particular scheme, urn:, specified by RFC2141 and related documents, intended to serve as persistent, location-independent, resource identifiers.
