URI

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The URI specification defines a Uniform Resource Identifier (URI) as a compact string of characters for identifying an abstract or physical resource.

user

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The principal using a client to interactively retrieve and render resources or resource manifestations.

user session

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A delimited set of user clicks across one or more Web servers.

web client

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A client that is capable of accessing Web resources by issuing requests and render responses containing Web resource manifestations.

web collection

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A portion or section of a Web site , consisting of two or more Web pages, that represents a non-trivial, self-contained resource, but is still maintained by the same publisher of the overall Web site .

web core

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The collection of resources residing on the Internet that can be accessed using any implemented version of HTTP as part of the protocol stack (or its equivalent), either directly or via an intermediary.

Notes: By the term "or its equivalent" we consider any version of HTTP that is currently implemented as well as any new standards which may replace HTTP (HTTP-NG, for example). Also, we include any protocol stack including HTTP at any level, for example HTTP running over SSL.

web neighborhood

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The collection of resources directly linked from a Web resource.

web neighborhood

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A resource, identified by a URI, that is a member of the Web Neighborhood .

web page

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A collection of information, consisting of one or more Web resources, intended to be rendered simultaneously, and identified by a single URI. More specifically, a Web page consists of a Web resource with zero, one, or more embedded Web resources intended to be rendered as a single unit, and referred to by the URI of the one Web resource which is not embedded.

Note: The components of a Web page can reside at different network locations. The location of the Web page, however, is determined by the URI identifying the page.

Note: The scope of a Web page is limited to the collection of Web resources which are displayed simultaneously by requesting the Web page's URI. The components of a Web page actually rendered in a page view is client-dependent.

web periphery

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The collection of resources on the Web which is not part of the Web Core or the Web Neighborhood.

Concepts relating to the process of accessing Web resources and render Web resource manifestations.

web request

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A Web request is a request issued by a Web client. A Web request can be described as either:

Explicit Web request:

A request that is initiated manually by the user.

Implicit Web request:

A request that is initiated transparently by the Web client, without manual intervention on the part of the user, as an ancillary event corresponding to an explicit Web request.

and as either:

Embedded Web request:

A request for dereferencing a URI embedded within a Web resource manifestation: e.g., following the link in an HTML document, etc.

User-input Web request:

A request for dereferencing a URI supplied by the user directly to the Web client: e.g., typed into the address window, bookmarks, history, etc.

web request body

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

web request header

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The request header contains information about the request, information about the client itself, and potentially information about any resource manifestation included in the request.

web resource

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A resource, identified by a URI, that is a member of the Web Core.

Note: The URI identifying the Web Resource does not itself have to be found within the Web Core. That is, a URI written on a bus identifying a resource that is a member of the Web Core identifies a Web Resource.

web resource

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A resource manifestation generated by a Web resource.

web response

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A Web response is a response issued by a Web server.

web response body

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The response body (if any) of an HTTP response is used to carry the payload of the HTTP message.

web response header

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

The response header contains information about the response, information about the server itself, and potentially information about any resource manifestation which may or may not be included in the response.

web server

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A server that provides access to Web resources and which supplies Web resource manifestations to the requestor.

web site

From Web Characterization Terminology & Definitions Sheet (1999-05-24)

A collection of interlinked Web pages, including a host page , residing at the same network location. "Interlinked" is understood to mean that any of a Web site's constituent Web pages can be accessed by following a sequence of references beginning at the site's host page ; spanning zero, one or more Web pages located at the same site; and ending at the Web page in question.

1. http://www.w3.org to http://www.w3.org/WCA/, and
2. http://www.w3.org/WCA/ to http://www.w3.org/WCA/1998/12/aut_char.html

Notes: It is not uncommon for Web sites to be duplicated, or mirrored, on multiple physical host machines (e.g., for load balancing purposes). Typically, it is immaterial to the client (or user) which host machine is used to access the Web site.In this case, it may be useful to consider this collection of "physical" Web sites, located at multiple host machines, as one "logical" Web site.This is possible in the case where a single domain name is mapped to each of the host machines; the logical Web site can then be identified using the unique domain name.If there is no unique domain name that can be applied to the collection of duplicate sites, we consider each physical host machine as a separate Web site.
