a precise, context-rich definition of each dictionary component. Schema Subset Generation Tool The Schema Subset Generation Tool (SSGT) enables users to search through the NIEM data model, view information about NIEM elements and types, and build a custom XML Schema subset of a NIEM release. The NIEM data model contains over 12,000 elements and represents over a dozen domains; subsets allows users developing an IEPD to select only what they need based on the specific requirements of the exchange. With this tool users can: Search and explore the NIEM data model. Build a schema subset containing the components required by the exchange. Download the current subset as a zip file (go to Generate Documents -> Save Subset Schema to a file). Resume editing a previous subset (go to Options -> Load Wantlist and upload the wantlist.xml file contained in a previously downloaded subset). Switch between any NIEM release (go to Options -> Change Release to). Download already generated subsets from each domain. Conformance Testing Assistant The Conformance Testing Assistant (ConTesA) enables the user to test NIEM XML schemas against the automated rules from the NIEM Naming and Design Rules (NDR). This is an important first step in verifying NIEM conformance. Users can upload a single NIEM XML schema or a zip file (typically representing an IEPD) and view or download the results as a conformance report. Movement Movement enables the user to search and explore the content of the latest NIEM release. It provides a user friendly interface and smarter search results. It is also open source: the community who inspired its creation can contribute to it. Migration Tool The Migration Tool enables the user to upgrade a NIEM XML Schema release subset generated by the SSGT to the next release. Multiple migrations can be run to upgrade to a non-consecutive release. Tools Catalog See the NIEM Tools Catalog for other tools developed by the NIEM community.
