Altova and NIEM (the National Information Exchange Model)

In February this year I was invited to give the keynote address at the NIEM Town Hall meeting in Washington, DC, to talk about how Altova tools can support projects that facilitate the National Information Exchange Model (NIEM). In particular, I covered the use of Altova tools in the life cycle of developing the Information Exchange Package Documentation (IEPD). The slides from that speech are now available on slideshare and a recap of the NIEM town hall meeting is also available on the NIEM website.

Since then we’ve been working with NIEM to add new features to the Altova product line that further support the NIEM development cycle and in particular our recent release of XMLSpy 2010r3 adds two features that are very important for NIEM:

  1. NIEM defines a set of Naming and Design Rules (NDR) that specify how XML Schemas for a NIEM-conformant information exchange have to be constructed. XMLSpy now includes an extended schema validation function that allows a developer to validate a schema against naming and coding conventions, and in particular XMLSpy ships with a set of extended validation rules that allow validation against the NIEM NDR.
  2. Another important step during the development for an IEPD for a NIEM-conformant information exchange is the production of example XML files that demonstrate the data that can be exchanged. To provide better example files, XMLSpy now lets developers specify user-defined example values for each element, attribute, or type in an XML Schema. During the generation of example XML files XMLSpy then uses these user-defined example values to produce meaningful example documents that are immediately suitable for documentation and testing purposes.

Further details about Altova tools for NIEM can be found in the Solutions Center on the Altova website and also in today’s article Altova adds to NIEM support in v2010r3 on the Altova Blog.
