workspace<br />

A container for file-based geographic data. A workspace can be a<br />

folder that contains shapefiles, an ArcInfo workspace that<br />

contains coverages, a personal geodatabase, or an ArcSDE<br />

geodatabase.<br />

World Wide Web Consortium (W3C)<br />

An organization that develops standards for the World Wide<br />

Web and promotes interoperability between Web technologies,<br />

such as browsers. Members from around the world contribute to<br />

standards for XML, XSL, HTML, and many other Web-based<br />

protocols.<br />

eXtensible Markup Language (XML)<br />

Developed by the World Wide Web Consortium (W3C), XML is a<br />

set of rules for designing text formats, designed to facilitate more<br />

standardized and structured documents. XML is a subset of the<br />

Standard Generalized Markup Language (SGML), the standard<br />

markup language for creating a digital document structure. XML<br />

is similar to HTML in that it uses markup symbols (tags) to<br />

encode information. But while HTML tells browsers how to<br />

display information on a Web page, XML defines values for the<br />

information. Also, users can create their own XML tags.<br />

eXtensible Style Language (XSL)<br />

A set of standards for defining XML document presentation and<br />

transformation. An XSL stylesheet may contain information about<br />

how to display tagged content in an XML document, such as<br />

font size, background color, and text alignment. An XSL<br />

stylesheet may also contain XSLT code that describes how to<br />

transform the tagged content in an XML document into an output<br />

document with another format. The World Wide Web Consortium<br />

(W3C) maintains the XSL standards. See also stylesheet, World<br />

Wide Web Consortium (W3C).<br />

eXtensible Style Language Transformations<br />

(XSLT)<br />

A language for transforming the tagged content in an XML<br />

document into an output document with another format. An XSL<br />

stylesheet contains the XSLT code that defines each<br />

transformation to be applied. Transforming a document requires<br />

the original XML document, an XSL document containing XSLT<br />

code, and an XSLT parser to execute the transformations. The<br />

World Wide Web Consortium (W3C) maintains the XSLT<br />

standard. See also stylesheet, eXtensible Style Language (XSL),<br />

XPath<br />

XML Path Language. XPath provides a way to address and<br />

match parts of an XML document and provides basic functions<br />

for manipulating values. Path notation, like the notation for<br />

defining a URL or the location of a file on disk, is used to<br />

navigate the hierarchical structure of an XML document and<br />

identify the part of the document that is of interest.<br />
