An interactive tool to traverse and search XML schemas - similar to NIEM wayfarer but it works with any schema. It contains the LEXS 3.1.4 and NIEM 2.0 standard schemas.

The Conformance Testing Assistant (ConTesA) is a tool for validating & viewing instances based on the specification. If you have written any code to perform a LEXS submission, you can submit your generated XML instances at ConTesA and receive feedback on whether or not your instances are actually valid, according to the rigorous business rule requirements of most LEXS-based IEPDs. If you have a custom IEPD, you can submit it to the ConTesA team and have ConTesA validate instances of your IEPD as well.

If you are in a secure or firewalled environment and/or have sensitive data that you cannot upload to an Internet site, ConTesA provides a downloadable command line client and a Linux-based bootable DVD for running on your local PC.

Tools that assist in creating and managing IEPDs for NIEM. There are actually several tools here, from navigating the entire NIEM model, subsetting it, mapping to it, and validating your own exchanges, so take your time and look around carefully at this wonderful site.

The LEXS 3.1 Sample Implementation includes web services and clients based on both JDOM and JAXB. Testers can utilize the sample clients to test their own web services, or the sample web services to test their own clients. The code is available for use by developers as a template for their own development or as an example that can be used for reference purposes. The sample implementation also includes a stylesheet that converts LEXS 3.1.4 instances to LEXS 3.1.3 instances, which may be of use to developers who want their applications to be compatible with multiple versions of the specification.
