New Course for Fall, LSC653-Data on the Web

The department is pleased to announce a new course, LSC653 Data on the Web, to be offered every fall semester in support of the Data Science Course of Study.

The course description:

Information professionals encounter a variety of data on the web from finding aids to APIs (Application Programming Interfaces), metadata, catalogs, and social media archives. Some questions would arise with this trend, for example:

  • How can metadata records be processed on the Web?
  • What kinds of data can be structured with XML?
  • What would be various applications of XML technologies?
  • How can APIs be used to access data and use results locally and on web applications?

LSC653 Data on the Web is designed to help you find answers to these questions and acquire skills and knowledge to understand, manage, manipulate and analyze data. Topics of the course include introduction to structured text formats (e.g., XML and JSON), introduction to JavaScript, processing of XML and JSON using JavaScript and XML-related technologies (XSLT, XPath, and XQuery), and introduction of use-case scenarios of APIs in information settings.

The course will include discussion of practical use of web-based data in information settings, demonstrations and examination of case studies, and hands-on activities. No prior programming skills are necessary for this course. However, prerequisite of LSC555 or prior experience with HTML is required.

Upon completion of the course, students will be able to: understand structured text formats and their use, query and process structured formats and serve results locally and on web applications, have basic experience writing web scripts in JavaScript, read and understand API documentation, understand the advantages of using APIs and structured data in information settings, and apply computational thinking to using programming languages and APIs in information scenarios.

Students who are interested in becoming data librarians, web librarians, metadata librarians, digital librarians, digital archivists, and other similar professions are encouraged to take the course. If you have any questions about the course, please feel free to contact Dr. Sue Yeon Syn (
