http://www.w3.org/Bugs/Public/show_bug.cgi?id=11379 Summary: 2.6.1 - definition of hierarchical URL inconsistent with rfc 3986 Product: HTML WG Version: unspecified Platform: All OS/Version: All Status: NEW Severity: normal Priority: P2 Component: HTML5 spec (editor: Ian Hickson) AssignedTo: ian@hixie.ch ReportedBy: glenn@skynav.com QAContact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-wg-issue-tracking@w3.org, public-html@w3.org Section 2.6.1 defines a hierarchical URL thus: "An absolute URL is a hierarchical URL if, when resolved and then parsed, there is a character immediately after the <scheme> component and it is a U+002F SOLIDUS character (/)." However, RFC3986 Section 3 defines all URIs as containing a hierarchical part as follows: URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ] and, further, does not require the hierarchical part to start with "/". In particular, it defines hier-part as: hier-part = "//" authority path-abempty / path-absolute / path-rootless / path-empty Which, when expanding these components into their definitions, corresponds to: hier-part = "//" authority | "//" authority 1*( "/" segment ) | "/" [ segment-nz *( "/" segment ) ] | segment-nz *( "/" segment ) | 0<pchar> Note that the last two alternatives do not start with "/", yet are still considered a "hierarchical" part by RFC3986. For example, the following URIs match this syntax, with hier-part mapping to path-rootless: about:blank file:foo/bar urn:example.net:foo:bar In order to avoid confusion, it may be desirable to use a different term in HTML5 than "hierarchical URL" in this regard. Alternatively, a note could be added which distinguishes the defined usage from the like named (but different) constructs in RFC3986. I would also note that, in terms of the definitions found in 2.6.1, all "authority-based URLs" are also "hierarchical URLs". I can't tell if this is intentional or not, if it is, then perhaps a note indicating this would be useful.
