idempotent

From Web Services Glossary (2004-02-11) | Glossary for this source

Property of an interaction whose results and side-effects are the same whether it is done one or multiple times. [RFC 2616]

Safe interactions are inherently idempotent.

identical

From Namespaces in XML 1.1 (2004-02-04) | Glossary for this source

image

From User Agent Accessibility Guidelines 1.0 (2002-12-17) | Glossary for this source

This content type label refers to all of the requirements related to images (excluding animated images) for the following checkpoints: 3.1 and 3.6. When this label is part of a conformance profile, the user agent must implement at least one image format. Furthermore, when this label is part of a profile, the user agent must satisfy these requirements for all implemented image formats, not just those identified in a conformance profile. The image requirements apply to image content that is recognized as distinct and that, according to the encoding format, may be rendered as a coherent unit.
This document uses the term "image" to refer (as is commonly the case) to pictorial content. However, in this document, term image is limited to static (i.e., unmoving) visual information. See also the definition of animation.
image

From Web Content Accessibility Guidelines 1.0 (1999-05-05) | Glossary for this source

A graphical presentation.An image that has been divided into regions with associated actions. Clicking on an active region causes an action to occur.When a user clicks on an active region of a client-side image map, the user agent calculates in which region the click occurred and follows the link associated with that region. Clicking on an active region of a server-side image map causes the coordinates of the click to be sent to a server, which then performs some action.Content developers can make client-side image maps accessible by providing device-independent access to the same links associated with the image map's regions. Client-side image maps allow the user agent to provide immediate feedback as to whether or not the user's pointer is over an active region.
image data

From Portable Network Graphics (PNG) Specification (Second Edition) (2003-11-10) | Glossary for this source

1-dimensional array of scanlines within an image.

From QA Framework: Specification Guidelines (2005-08-17) | Glossary for this source

Implementation-defined indicates an aspect that may differ between implementations, but must be specified by the implementor for each particular implementation.
implementation dependent

From XQuery 1.0 and XPath 2.0 Data Model (XDM) (2007-01-23) | Glossary for this source

Implementation-dependent indicates an aspect that may differ between implementations, is not specified by this or any W3C specification, and is not required to be specified by the implementor for any particular implementation.

From Voice Extensible Markup Language (VoiceXML) Version 2.0 (2004-03-16) | Glossary for this source
