XMLApe

Abstract

We envision XMLApe as a complete system for the composition, sharing, and reuse of XML schemata and for the storage, retrieval, manipulation, and transmission of XML data adhering these XML Schemata.

XMLApe has the following components:

A set-oriented graphical query and data manipulation language for collections of XML documents with shared schemata. The language will be closed, i.e., the query and data manipulation statements, the data
they access, and the results they produce will all have representations as XML documents.

A powerful database generator capable of automatically generating normalized relational database schemata, database storer software, and syntax-directed query and data manipulation interface support
directly from the schemata of XML documents.

An XML schema management interface through which it is much easier to find and reuse existing schemata in the composition of new ones than it is to define them from scratch. The interface will be generated
from a self-describing XML schema for XML schemata the same way relational database schema definitions, database storer software, and syntax-directed query and data manipulation interfaces are generated for XML data from their schemata. This XML Schema management interface will help prevent proliferation of schemata for data that "mean the same".

This research represents a strong database-point-of-view on the whole XML revolution.

Dr. Leo Mark received his M.S. degree in Mathematics and his Ph.D. degrees in Computer Science from Aarhus University, Denmark. He was an assistant professor at the Department of Computer Science, University of Maryland from 1986-1992. He joined the College of Computing at Georgia Tech as an associate professor in 1992. He has taught a number of database courses and seminars at Aarhus University, The University of Maryland, Georgia Tech, and for private companies. Dr. Mark has participated in database architecture standardization efforts for ANSI/SPARC, researched a standardized communication environment for NASA, researched High Performance Engineering Information Systems for the National Science Foundation, and published over 50 journal and conference papers on database systems.
