security service

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

A processing or communication service that is provided by a system to give a specific kind of protection to resources, where said resources may reside with said system or reside with other systems, for example, an authentication service or a PKI-based document attribution and authentication service. A security service is a superset of AAA services. Security services typically implement portions of security policies and are implemented via security mechanisms. [RFC 2828]

selected

From XML Inclusions (XInclude) (2004-12-20) | Glossary for this source

An information item is said to be selected by a range if it occurs after (in document order) the starting point of the range and before the ending point of the range.
selected sub-expression (of an maction element)

From Mathematical Markup Language (MathML) Version 2.0 (2001-02-21) | Glossary for this source

The argument of an maction element (a layout schema defined in Section 3.6 [Enlivening Expressions]) that is (at any given time) `selected' within the viewing state of a MathML renderer, or by the selection attribute when the element exists only in MathML data. Defined precisely in the abovementioned section.
selection, current selection

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

In this document, the term "selection" refers to a user agent mechanism for identifying a (possibly empty) range of content. Generally, user agents limit the type of content that may be selected to text content (e.g., one or more fragments of text). In some user agents, the value of the selection is constrained by the structure of the document tree. On the screen, the selection may be highlighted in a variety of ways, including through colors, fonts, graphics, and magnification. The selection may also be highlighted when rendered as synthesized speech, for example through changes in speech prosody. The dimensions of the rendered selection may exceed those of the viewport.The selection may be used for a variety of purposes, including for cut and paste operations, to designate a specific element in a document for the purposes of a query, and as an indication of point of regard.The selection has state, i.e., it may be "set," programmatically or through the user interface.In this document, each viewport is expected to have at most one selection. When several viewports coexist, at most one viewport's selection responds to input events; this is called the current selection.See the section on the Selection label for information about implementing a selection and conformance.Note: Some user agents may also implement a selection for designating a range of information in the user agent user interface. The current document only includes requirements for a content selection mechanism.
semantic

From RDF Semantics (2004-02-10) | Glossary for this source

(adj.) , (n.). Concerned with the specification of meanings. Often contrasted with syntactic to emphasize the distinction between expressions and what they denote.
semantic requirement

From W3C QA - Quality Assurance glossary (2003-09-06) | Glossary for this source

Same as test assertion
semantic web

From Glossary of "Weaving the Web" (1999-07-23) | Glossary for this source

The Web of data with meaning in the sense that a computer program can learn enough about what the data means to process it.
semantically transparent

From Hypertext Transfer Protocol -- HTTP/1.1 (1999-06-15) | Glossary for this source

A cache behaves in a "semantically transparent" manner, with respect to a particular response, when its use affects neither the requesting client nor the origin server, except to improve performance. When a cache is semantically transparent, the client receives exactly the same response (except for hop-by-hop headers) that it would have received had its request been handled directly by the origin server.
sender

From Composite Capability/Preference Profiles (CC/PP): Structure and Vocabularies 1.0 (2004-01-15) | Glossary for this source

A system component (device or program) which transmits a message.
separation of form from content

From Glossary of "Weaving the Web" (1999-07-23) | Glossary for this source

The principle that one should represent separately the essence of a document and the style with which it is presented. An element in my decision to use SGML and an important element in the drive for accessibility on the Web.
sequence

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

A sequence is an ordered collection of zero or more items.
sequence

From XQuery 1.0: An XML Query Language (2007-01-23) | Glossary for this source

A sequence is an ordered collection of zero or more items.
sequence

From XML Path Language (XPath) 2.0 (2007-01-23) | Glossary for this source

A sequence is an ordered collection of zero or more items.
sequence constructor

From XSL Transformations (XSLT) 2.0 (2007-01-23) | Glossary for this source

A sequence constructor is a sequence of zero or more sibling nodes in the stylesheet that can be evaluated to return a sequence of nodes and atomic values. The way that the resulting sequence is used depends on the containing instruction.
sequence type

From XQuery 1.0: An XML Query Language (2007-01-23) | Glossary for this source

A sequence type is a type that can be expressed using the SequenceType syntax. Sequence types are used whenever it is necessary to refer to a type in an XQuery expression. The term sequence type suggests that this syntax is used to describe the type of an XQuery value, which is always a sequence.
sequence type

From XML Path Language (XPath) 2.0 (2007-01-23) | Glossary for this source

A sequence type is a type that can be expressed using the SequenceType syntax. Sequence types are used whenever it is necessary to refer to a type in an XPath expression. The term sequence type suggests that this syntax is used to describe the type of an XPath value, which is always a sequence.
sequenceType matching

From XQuery 1.0: An XML Query Language (2007-01-23) | Glossary for this source

During evaluation of an expression, it is sometimes necessary to determine whether a value with a known dynamic type "matches" an expected sequence type. This process is known as SequenceType matching.
sequenceType matching

From XML Path Language (XPath) 2.0 (2007-01-23) | Glossary for this source

During evaluation of an expression, it is sometimes necessary to determine whether a value with a known dynamic type "matches" an expected sequence type. This process is known as SequenceType matching.
serial access, sequential navigation

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

In this document, the expression "serial access" refers to one-dimensional access to rendered content. Some examples of serial access include listening to an audio stream or watching a video (both of which involve one temporal dimension), or reading a series of lines of braille one line at a time (one spatial dimension). Many users with blindness have serial access to content rendered as audio, synthesized speech, or lines of braille. The expression "sequential navigation" refers to navigation through an ordered set of items (e.g., the enabled elements in a document, a sequence of lines or pages, or a sequence of menu options). Sequential navigation implies that the user cannot skip directly from one member of the set to another, in contrast to direct or structured navigation (see guideline 9 for information about these types of navigation). Users with blindness or some users with a physical disability may navigate content sequentially (e.g., by navigating through links, one by one, in a graphical viewport with or without the aid of an assistive technology). Sequential navigation is important to users who cannot scan rendered content visually for context and also benefits users unfamiliar with content. The increments of sequential navigation may be determined by a number of factors, including element type (e.g., links only), content structure (e.g., navigation from heading to heading), and the current navigation context (e.g., having navigated to a table, allow navigation among the table cells).Users with serial access to content or who navigate sequentially may require more time to access content than users who use direct or structured navigation.
serialization

From XSL Transformations (XSLT) 2.0 (2007-01-23) | Glossary for this source

A frequent requirement is to output a final result tree as an XML document (or in other formats such as HTML). This process is referred to as serialization.
