XML Rules Engine and Validation Tutorial with NIEM
- by drrwebber
Our new XML Validation Framework
tutorial video is now available.
See how to easily integrate code-free adaptive XML validation services into your
web services using the Java CAMV validation engine.
CAMV allows you to build fault tolerant content checking with
XPath that optionally use SQL data lookups. This can provide warnings as
well as error conditions to tailor your validation layer to exactly
meet your business application needs.
Also available is developing test suites using Apache ANT scripting of validations. This allows a community to share sets of conformance checking
test and tools .
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.
