XML and Semantic Services
‘Rise of the internet age’ is something which explains the 21st century in one short phrase. This advent has paved way for innumerable programming languages and technologies. One such language is the XML, an acronym for Extensible Mark-up Language. XML is a set of rules which make up for a syntax which is both human readable and machine readable. This exclusive support the language provides is the reason behind the extensive use of this language for almost all computing activities. XML is primarily used in writing codes for the internet and several computer programmes. Microsoft office applications use the XML scripts and encoding for most of its utility applications. Internet services also use the XML encoding for web pages and other such web applications. Which such wide applicability and prospective career, a course in XML and Semantic Services might just be the thing for anyone.
The course on XML and Semantic looks at XML from the perspective of data management. A student looks at structured data and semi structured data models and contrast it with relational data model and unstructured data. After completing the course a student is generally able to author XSLT style sheets to transform documents into XHTML and other mark-up languages; create well-formed XML documents; create DTDs and simple Schemas, and check validity of XML documents with respect to these schemas; understand and contrast the semi-structured data model with the relational data model and unstructured data; have some knowledge of assorted mark-up languages; understand and contrast DOM and SAX parsers; translate English language query statements to XPath and XQuery expressions; understand the use and challenges of XML-based databases; understand and use the concepts behind web services and the Semantic Web. Thoroughly covering the dynamics of the field, this course enables one to work in a professional and challenging where he or she would need the in-depth knowledge about the field, which is covered in details in the course.
The course is spread in different units which significantly cover more or less the entire curriculum which comes under the umbrella, the topics are: Schema Languages for XML; Parsing with SAX and DOM; XML Transformations; Markup Languages; Native XML Databases; Web Services and Semantic Web. The curriculum is designed in such a way that extensive study of the same will make the student aware about the topic exhaustively. The course also requires some assignment by the student to be submitted, in order for the student to be awarded. Upon successful completion of the assignments the student undergoes a written exam which tests the student’s skills based on what he has leant previously.
This course helps the student in multifaceted ways empowering him or her to work in a dynamic role leading the progress of his or her organisation. Universities all over the world provide a course in XML and semantic services, such as the University of Southern Queensland which offers the course by the same name and with ‘CSC8409’ as the course code, Columbia University provides a similar course by the name Introduction to Semantic Web and the course code being ‘COMS4995’.
