Creating, using and managing XML component dictionaries quick tutorials

XML Component Dictionary capabilities are provided in conjunction with the CAM Editor toolset.  These dictionaries accelerate the development of consistent XML information exchanges using standard sets of dictionary components.

The quick tutorials are aimed at showing the 'how to' of the basic capabilities to jump start use of XML dictionaries with the CAM Editor.

The collection of dictionary tutorials videos run for a total of approximately 20 minutes.  Each video can be reviewed individually also.

Learn how to use the dictionary functions to create dictionaries by harvesting data model components from existing XSD schema, SQL database table schema, or simple Excel / Open Office spreadsheets with tables of components listed.

Also included are tips and functions relating to use of NIEM exchange development, IEPD and EIEM techniques.

These videos should be viewed in conjunction with reviewing the overall concepts and techniques described in the companion video on the CAM Editor and Dictionaries overview.  The approach is aligned with OASIS and Core Components Technical Specification (CCTS) standards specifications for XML components and dictionaries.

Dictionary collections can be stored locally on the file system, or local network, or collaboratively on the web or cloud deployment, or can be shared and managed securely using the Oracle Enterprise Repository (OER) tool.

Also included are techniques relating to the use of the NIEM approach for developing XML exchange schema and IEPD packages.  This includes generating reuse scores, wantlist, and cross reference spreadsheets.

Included in the latest release of the CAM Editor is the ability to use the analyse dictionary tool to determine duplicate components, conflicting component definitions, missing component descriptions and so on.  This ensures high quality dictionary component specifications.  Using the CAM Editor you can also create MindMap models and UML physical models of your dictionary components sets.

For a complete guide to using the CAM Editor see the main YouTube video tutorials website and the CAM Editor website.

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.
