URIs [RFC3986] very often include structured application data. This might include artifacts from filesystems (often occurring in the path component) and user information (often in the query component). In some cases, there can even be application-specific data in the authority component (e.g., some applications are spread across several hostnames to enable a form of partitioning or dispatch).

Internet Engineering Task Force (IETF)                     M. Nottingham Request for Comments: 7320 BCP: 190                                                       July 2014 Updates: 3986 Category: Best Current Practice ISSN: 2070-1721

                         URI Design and Ownership


   Section 1.1.1 of RFC 3986 defines URI syntax as "a federated and    extensible naming system wherein each scheme's specification may    further restrict the syntax and semantics of identifiers using that    scheme."  In other words, the structure of a URI is defined by its    scheme.  While it is common for schemes to further delegate their    substructure to the URI's owner, publishing independent standards    that mandate particular forms of URI substructure is inappropriate,    because that essentially usurps ownership.  This document further    describes this problematic practice and provides some acceptable    alternatives for use in standards.
