New CAM v3.0 ships with JSON support and significant performance enhancements

Today we released the new and significantly improved CAM editor toolset along with 3 new companion 'How to' quick videos (see here to view).

The main focus is integrating JSON handling alongside the existing XML capabilities to provide developers with the ability to use either or both from the single set of infrastructure.

This provide JSON developers with the ability to quickly build visual data models, use robust XML content validation services and generate XSD schema and JAXB bindings without having to do all those tasks by hand or know the nuances of complex XSD schema or XML handling.

For XML developers it provides a rapid ability to use JSON as an option in their information exchanges and web service integration for supporting mobile and web-based application needs.

In addition to these new JSON capabilities the existing functionality has significantly improved performance and capability.  The CAMV validation engine now runs up to 20 times faster for large XML validation input and with templates containing setChoice() rules.  For comparison a 500+ rules validation template with large 15MB sample COBie CAD/CAM smart building XML export now runs in 19 seconds instead of previously taking over 9 minutes.

Then the drag and drop dictionary components handling has similarly been significantly improved.  Large sets of components now are inserted in real time with low memory overhead thus dramatically improving the user experience and ability to quickly build information exchanges from XML dictionaries of predefined domain components.  The video shows using the Education domain to rapidly build a StudentDetails report with grades, achievements and student data.

For the Open-XDX open data API toolset we have added bi-directional support.  This means using the same CAM template and the SQL drag and drop interface you can design Update/Insert SQL database web services along with the query services.  Again the focus is on providing simple and rapid application development support.  Example code and resources can be found at our GitHub site while on line demonstrations are available from the VerifyXML.org site.

Further enhancements include a new Dictionary Evaluation report.  This tool analyzes the XML components in a dictionary and highlights design issues, omissions, duplicates and more that would be extremely tedious to detect by hand.  This allows a development team to collaboratively improve the quality of their core components and their reuse across a project implementation.

Last but not least we have improved the XSD schema importing and exporting resolving a range of complexity nuances not previously handled allow improved accuracy and compatibility with XSD schema.

In summary the new release provides:

o All new JSON capabilities and template type
o Bi-directional data processing using Open-XDX for open data query and update
o Dramatically improved Dictionary components drag and drop
o New report for Dictionary evaluation and analysis
o Significant CAMV rules engine performance improvements
o Better XSD schema importing and exporting

We look forward to seeing the enhanced solutions this helps people deliver to their customers.

XML Rules Engine and Validation Tutorial with NIEM

.

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.

NIEM / LEXS starter kit now available with JAX-WS and JDeveloper examples

The Oracle NIEM team is pleased to announce the availability of a starter kit to assist in rapidly developing NIEM solutions using Java. The kit uses the LEXS 3.1.4 Search/Retrieve schema as examples.

You can find out more and download the how to step by step guides along with sample source code from this link here.

About

Not all XML is created equal. XML Orb looks at the challenges of creating information exchanges with XML and NIEM and how this can be made simpler, comprehensible, consistent and reliable.
