XML Rules Engine and Validation Tutorial with NIEM
By drrwebber on Nov 05, 2012
On the technical XML side the video introduces XPath validation rules and illustrates and the concepts of XML content
and structure validation. CAM validation templates allow contextual
parameter driven dynamic validation services to be implemented compared
to using a static and brittle XSD schema approach.
The SQL table lookup and code list validation are discussed and examples presented.
Features are highlighted along with a demonstration of the interactive generation of actual live XML data from a SQL data store and then validation processing complete with errors and warnings detection.
The presentation provides a primer for developing web service XML validation and integration into a SOA approach along with examples and resources. Also alignment with the NIEM IEPD process for interoperable information exchanges is discussed along with NIEM rules services.
The CAMV engine is a high performance scalable Java component for rapidly implementing code-free validation services and methods. CAMV is a next generation WYSIWYG approach that builds from older Schematron coding based interpretative runtime tools and provides a simpler declarative metaphor for rules definition.
