URI

Abbreviation · Development

Definitions

  1. Uniform Resource Identifier — a compact string defined by RFC 3986 that identifies a resource either by location (a URL), by name (a URN), or both. Every URL is a URI, but not every URI is a URL; for example, 'urn:isbn:0451450523' identifies a book without telling you where to fetch it.

    In plain English: A standardized string that names or points to a resource, like a web address or a book's ISBN in a special format.

    Example: "The OAuth spec says 'redirect_uri' but in practice it's always a URL — nobody uses URNs for redirects."
