NISTITL XML Workgroup Recommendation

ANSI/NIST-ITL 1-2007
Data Format for the Interchangeof Fingerprint,
Facial, Other Biometric Information
XML Workgroup
Gerry Coleman, chair coleman_at_doj.state.wi.us
Recommendations to the NIST Workshop September
18, 2007 Gaithersburg, MD
2
Objectives
A complete XML representation of the 1-2007
specification. Field/subfield mapping of Part 1
to Part2 XML elements. Preserve backward
compatibility. Conform to NIEM extension
rules. Use, where possible, NIEM 2.0
objects. Define a NIST-ITL namespace. Conform
to NIEM IEPD requirements. Recommend additions
and repair content in the ANSI-NIST namespace of
NIEM.
3
Part 1 and 2 Differences

• No Logical Record Length
• No field identifiers or mnemonics
• Different element ordering
• There are no binary records or content
• Images are expressed in Base-64 coding

4
Part 1 and 2 Similarities

• Every record is represented, in the same order
• Part 1 fields map to Part 2 element(s)
• Except Logical Record Length
• Some repeat (09.008 CRP) ltMinutiaeFingerCorePosi
  tiongt
• Some are split (01.002 VER)
  ltTransactionMajorVersionValuegt
  ltTransactionMinorVersionValuegt
• Package content is summarized in the first record
• Each record carries an image ID pointer

NIEM ansi-nist content requiring correction

• ltMinutiaQualityValuegtltMinutiaCategoryCodegtltMinut
  iaRidgeCountgt move from MinutiaeNISTStandardType
  to MinutiaDetailType
• GCACodeSimpleType has only numeric
  ennumerations needs text abbreviations, like
  JPEG. E.g., see 10.011 CGA.
• ltPatternCodeSourceCodegt is typed as a Pattern
  type like PW, but should be T or U

8
NIEM ansi-nist content requiring extension

• To FingerprintImageType add ltFingerprintFingerM
  issinggt ltFingerprintImageNISTQualitygt ltFingerpri
  ntImageSegmentPositionPolygongt ltFingerprintImageS
  egmentPositionSquaregt
• To IrisImageType add ltIrisDiameterPixelQuantity
  gt
• Add RecordImage substitution group

9.1.6 Element ltTransactionPriorityValuegt When
this element is used, it shall contain a single
information character to designate the urgency
with which a response is desired. The values
shall range from 1 to 9, with "1" denoting
the highest priority. The default value shall be
defined by the agency receiving the
transaction. The comment line displaying FieldID
and mnemonic is optional. Example lt! FieldID

NIST-ITL XML Workgroup Recommendations
1. Adopt this XML proposal as a PART 2
alternative version of ANSI/NIST-ITL
1-2007. 2. Endorse error corrections and
extenstions to the ansi-nist domain within
NIEM. 3. Register at OJPs IEPD Clearinghouse
(http//it.ojp.gov/iepd/).
