|Course Description (Catalog) |

This course is a study of the concepts and applications of the Extensible Markup Language (XML), a general-purpose markup language that can be used to formally specify special-purpose markup languages. This course will be taught from a mixture of analytical and practical methods. Topics include: the history of XML, the XML language, Data Type Definition (DTD), XML Schema, eXtensible Style Sheet Language (XSL), and eXtensible Style Sheet Language Transformations (XSLT). The student will bind values to elements to render them distinct and different from its other instances of that attribute and explore the power of XML as a tool for Enterprise Exchange in both the J2EE and .NET Software Development Frameworks. Knowledge of XML will enable the student to standardize and reuse reference text, paragraphs, and chapters. (Prerequisite: WEBD121) [3 Semester Hours]

|Course Scope |

This course is a study of the concepts and applications of Extensible Markup Language (XML), which enables students to define their own “tags.” Course topics include the differences between XML and HTML. Students will learn the XML syntax, to include Data Type Definition (DTD), which will enable students to specify all the structural elements of an XML document. They will learn the Attributes to bind a value to an element so it is distinct and different from other instances of that element. Knowledge of XML will enable the student to standardize and reuse and reference text, paragraphs, and chapters.

|Course Objectives |

The successful student will fulfill the following learning objectives:

1. Examine the evolution of the World Wide Web (WWW) in terms of the need for a general-purpose markup language. 2. Draw conclusions about the power and advantages of XML that have made it the global standard for enterprise data exchange.
3. Compare and contrast Data Type Definitions (DTD) and XML Schemas.
4. Evaluate Global Elements, NameSpaces, and XML Metadata Models (XHTML, DocBook, Resource Description Framework (RDF), and Really Simple Syndication (RSS).
5. Interpret the need, the principles, and the power of XSL and XSLT to create new content, manage site layout, extract information, and for document format conversion.
6. Discuss the process for creating XML documents and apply this knowledge to develop XML and DTD documents.
7. Analyze the ability of XML to facilitate inter-application and inter-tier communications.
8. Apply XSL and XSLT to standardize the look and feel across pages and to generate multiple formats of the same page.
