XSL Transformations
(XSLT) [top]
Australian Government Architecture Reference Models Version 3.0
A XML-based declarative language used for the transformation of XML
documents. The original document is not changed; rather, a new XML
document is created based on the content of the original document. The new
document may be serialised (output) by the processor in standard XML syntax
or in another format, such as HTML or plain text. XSLT is most often used to
convert data between different XML Schemas or to convert XML data into web
pages or PDF documents. It can also be used to extract portions of an XML
document. (More: W3C XSL page)
Note: ‘XSL’ stands for Extensible Stylesheet Language, which includes XSLT,
XSL-FO (XSL Formatting Objects), and XPath.
XSLT Stylesheets [top] A transformation expressed in XSLT is called a stylesheet. A stylesheet
contains a set of template rules. A template rule has two parts: a pattern which
is matched against nodes in the source tree and a template which can be
instantiated to form part of the result tree. This allows a stylesheet to be
applicable to a wide class of documents that have similar source tree
structures. (More: W3C XSLT 1.0 Recommendation).
Z39.50 [top] National Information Standards Organisation (NISO) Z39.50 Information
Retrieval Protocol (ANSI/NISO Z39.50 or ISO 23950). A computer protocol that
can be implemented on any platform and defines a standard way for two
computers to communicate for the purpose of information retrieval. A Z39.50
implementation enables one interface to access multiple systems providing the
end-user with nearly transparent access to other systems. (NISO Z39.50
Resource Page)
Notes:
Despite a common misconception to the contrary, Z39.50 is not simply used by
libraries. The standard specifies a client/server-based protocol for searching
and retrieving information from remote databases. (More: Z39.50 Maintenance
Agency Page at the US Library of Congress)
1. Sources are indicated in parentheses. The phrase ‘(DRM usage)’ denotes either a term
that is unique to the DRM or that has a slightly different connotation when used in the
context of the DRM.
2. Many of the context-related definitions are taken from the Z39.19-200x document,
Guidelines for the Construction, Format, and Management of Monolingual Controlled
Vocabularies. The glossary starts on page 172 of the PDF version of the document.
