NIEM Java Binding Tool

An open source Java tool that uses Maven and JAXB to implement NIEM-based exchanges. The functions within the tool can generate consistent bindings to Java objects for NIEM schema subsets and extension schema documents. It contains example REST services with XML, and can:

  • Generate binding configuration files based on an IEPD
  • Generate Java binding classes at compile time for NIEM schema documents and package into a reusable jar
  • Accommodate updates to an IEPD through unit testing in the project
  • Run sample tests of bindings that generate random data for the IEPD, verifying correctness of the exchange implementation

Crossflo CDX ExchangeBuilder

CDX ExchangeBuilder is a COTS design-time tool that automates the processes and reduces the time associated with creating NIEM MPDs, IEPD’s and LEXS Digest messages. It provides full lifecycle management of all exchange artifacts, built upon a pure XML semantic metadata registry. The CDX registry contains a comprehensive canonical model of all the data elements, definitions, and relationships for creating business models, logical models, and physical schema packages for information exchanges. ExchangeBuilder contains a notation-neutral GUI and includes an automated, wizard-driven tool that allows users to create their own repository to build IEPDs using NIEM objects. The CDX ExchangeBuilder has been granted a U.S. Patent for its novel approach to both the creation of NIEM IEPD’s (using an ISO 11179-compliant XML Registry and Repository) and it’s unique and powerful platform for the management of enterprise exchange artifacts, which can be either hosted locally or accessed via secure cloud-based SaaS.

CAM Editor Toolkit

The CAM editor is an open source toolkit for building and deploying information exchanges and Open Data APIs using NIEM and XML or JSON with SQL. The CAM toolkit provides an intuitive approach using a WYSIWYG visual structure editor to dramatically simplify the process of developing and managing XML business information exchanges and schema. This gives developers control, insights and analysis that are needed for consistent, interoperable and reliable exchanges. The CAM toolkit also automates the tasks of generating supporting artifacts such as NIEM IEPD business documentation, cross-reference spreadsheets, component dictionaries, models, XML Schema, XMI, JAXB data bindings and test XML instances generation including SQL data extracts. Visual SQL data mapping to existing SQL databases and Open Data web service generation is also provided. Runtime exchange validation services integration with middleware is delivered with the CAMV Java engine including XPath business rules. Complete lifecycle delivery for NIEM exchanges and IEPDs and associated web services and data integration is also available.
