Normalization theory for XML

Normalization Theory for XML

Specifications of XML documents typically consist of typing information (e.g., a DTD), and integrity constraints. Just like relational schema specifications, not all are good – some are prone to redundancies and update anomalies. In the relational world we have a well-developed theory of data design (also known as normalization). A few definitions of XML normal forms have been proposed, but the...

XML Document Normalization Using GN-DTD

RDF syntax normalization using XML validation

Basing the Semantic Web stack on XML promised to introduce a lot of advantages by reusing tools and expertise. In general, these promises have not been fulfilled. In this paper we describe a method that re-uses existing standards creatively in order to provide a guaranteed serialization of an RDF graph that can again be used easily with widely spread XML tools and techniques like SAX, DOM, or X...

Conceptual Model Based Normalization of XML Views

As the popularity of XML as a format for data representation grows the need for storing XML data in an effective way grows as well. Recent research has provide us with effective solutions based on storing XML data into relational databases and with new technologies based on storing XML data in the native form. However, design of XML databases has not been studied sufficiently yet. In this paper...

Towards An XML-Based Normalization for Healthcare Data Exchanges

Problem statement: Most of healthcare data exchanges are textual, poorly structured and often not accessible by clinical professionals. Otherwise, the variety of medical applications and medical standards makes difficult sharing and communicating healthcare data in a highly heterogeneous environment. Approach: XML and related standards (XML schema, XSL) provided an infrastructure that might cha...
