In this course we will implement an interpreter for Onyx, a subset of the XQuery data base query language. The interpreter will be built in stages: first a scanner, then a parser, and finally a semantic engine for Onyx.
The XQuery language is an active project in the World-Wide-Web Consortium ( w3c.org ). It is a rich language with many features and a flexible syntax. For the class project assignments, we will be using a simplified version of the full XQuery language, specifications for which will be distributed with the assignment descriptions.
