| On April 20, 2007, the ANSI Board of
Standards approved the new Data Format for the Interchange of
Fingerprint, Facial, & Other Biometric Information -- Part 1
This standard is published at http://fingerprint.nist.gov/standard. On July 31, 2007, the production version of NIEM 2.0 was published. It contained several changes that affected the 7/6/07 draft NIST-ITL XML proposal (in another box below). Technical materials for a Part 2 XML proposal, using the 7/31/07 production version of NIEM 2.0 as a data model, is available here: XML Draft NIST-ITL 1-2007 Part 2. Posted 05/29/2008.

This standard is published at http://fingerprint.nist.gov/standard. An XML version (to be called Part 2) is under development. A draft of the XML version, using NIEM 2.0 as a data model, is available here: XML Draft NIST-ITL 1-2007 Part 2. Posted 07/06/2007.

History:
| On October 19, 2006, Mike McCabe from NIST published a draft of the "2006" revisions to the standard. That
material has been converted into an XML specification which is posted here:
XML Representation of the proposed NIST-ITL 1-2006. Posted 1/12/2007.
|
Everything below is information and material produced
in 2005 to model the
NIST-ITL 1-2000 Version of the specification.
Workgroup Materials
| Documentation The schema and example
XML files have been moved to MS-Word documents for ease of reading and
printing. The spreadsheet has been formatted for printing. Presentation The MS-PowerPoint
presentation has been created in two versions: a printer-friendly version
for paper reproduction, and a graphics-loaded version for actual presentation to
the workshop audience. |
On December 5, 2005 the participants at the NIST Workshop (http://www.nist.gov/public_affairs/confpage/051205.htm) voted to move forward on the proposal above as an alternate representation of the biometric interchange standard. They asked to have the materials updated to include other revisions proposed for a 2006 version of the standard. That work will happen in early 2006, and a complete revised package will be published and visible to the ANSI canvass process.

Conference call participants reviewed and discussed materials below. There was substantial agreement that the "draft model proposal" is suitable for further refinement and presentation to the December, 2005 workgroup meeting scheduled to be held at NIST in Gaithersburg. Next call will be 11/8/05 and will focus on specific presentation materials for the meeting. Cherie Morgan produced a detailed set of notes describing this conference call available here. Thanks, Cherie!

Conference call (hosted by FBI/CJIS) had about 14 participants from the above list. The discussion focused on the content and advantages/disadvantages of four main options (see below). A straw vote was taken with the following outcome: (1)LEAN - 6 votes, (2)LEANER - 4 votes, (3)GJXDM - 2 votes, (4)CBEFF - 1 vote. There were several who voted for multiple options, and many who abstained or weren't ready to commit to anything in particular. Given that a strong majority seem favor a direct XML mapping from existing ITL-2000 structure and content (LEAN and LEANER), we will visit a more detailed example of the LEAN model at our next meeting.
To assist those still undecided, the pros and cons of each proposal will be published. Please send suggestions to coleman@doj.state.wi.us.
Next conference call will be 11:00 am Eastern US time, September 22, 2005.
Participants held a conference call to discuss procedural and content issues.
Among the comments and issues discussed were these:
| The resulting product should be easy, lean. |
| To what extent should this product facilitate convergence with M1 and CBEFF ? |
| To what extent should this product conform to the Global Justice XML Data Model (GJXDM) ? |
| To what extent should this product conform to ISO 11179 XML standards ? |
| How should binary data be handled? Base-64 encoding (See MIME spec section 6.8)? |
| Don't hurt the existing user community. What about backwards compatibility, stylesheet conversions? |
A sizable percentage of participants (and others who have submitted comments to me) are recommending that we develop an XML representation of the existing standard, mapping as closely as possible the existing records and numeric tags to XML tags. The tag names in this example are descriptive of the element content, using the language of the text of the current standard.
Aware, Inc. and Smith Heimann have offered examples that use XML to replace the NIST-ITL record, field, and subfield delimiters. This keeps the current structure. It does not create tag names that are representative of the element content.
GJXDM defines a process for extracting a sub-set of elements from the larger dictionary, and then extending that subset to create a particular specification.
OSS Nokalva has offered an example that uses "BIR"s (biometric information record) from the CBEFF specification.
