Abstract

The paper deals with the problems of businessrules implementation into the Web-based document management system. XML document storing, retrieving, querying, and transformation methods are analyzed. Different active methods based on ECA (event-condition-action) model have been discussed. An Active XQuery language is recognized as the most promising, but it lacks implementation means. A specialized XML extention is created and corresponding interpreter is developed to implement business rules into the document management system of the project MOCURIS. The method proposed can be used to solve similar tasks.
