An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints. XML Schema, published as a W3C recommendation in May 2001, is one of several XML schema languages. By attending this training you will learn how to write complex XML Schema documents and how to make the most out of its syntax. You will learn how to define elements, attributes, define groups of elements and attributes as building blocks and reuse them multiple times in the document design. You will then get to know the data type system which a standard of its own and to select suitable data types for elements and attributes - or to declare specifically derived new types. For complex documents, this training will show you how to define global complex types which may even be used for derivation (inheritance) and other more object-oriented techniques. The training finally shows how to bind Java and .NET classes to XML Schema structures or how to generate corresponding classes or XML Schema defintions.

Marco Skulschus (born in Germany in 1978) studied economics in Wuppertal (Germany) and Paris (France) and wrote his master´s thesis about semantic data modeling in XML, shortly before any of the current Semantic Web standards had been adopted. He started working as lecturer and consultant in 2002.
He works as an IT-consultant and project manager. He developed various XML-based applications with his team in India and is regularly involved in complex import/export scenarios / data integration projects and in XML-based reporting solutions.
He led several research projects for business partners concerning expert systems, ontology-based software, and also online questionnaires. Nearly all of these projects were based on a complex XML-data model or made use of XML-based rule sets.
