XML Proposal for NISTITL XML Workshop

XML Proposal for NIST-ITL XML Workshop

• David Rodman
• Nortel PEC Solutions

2
Summary of features

• Usage of Global Justice XML tags where
  appropriate
• Allow complete translation from EDI
  (NIST-ITL-2000) to XML translation. (forward
  translation)
• Allow for all allowable EDI tags to be generated
  when translating from XML to EDI formats, but
  also recognizing that some data or metadata
  (relationships) would be lost.
• Explicit rules for user or domain defined tags
  consistent with NIST-ITL-2000
• Enable complex relationships and attributes
  allowed by XML that cannot be expressed in EDI.

3
Use of tag attribute fields for EDI tags, groups
and unit placement

• XML has an ability to associate meta-data on
  tags.
• Syntax ltxmlTagName MyAttributeNametextgt
• GJXDM uses an ID/REF ID mechanism to associate
  tag groups that dont have a contains by
  relationship.
• XML requires all attributes to be simple types
  (e.g. string, integer, etc) complex or aggregate
  types are not allowed.
• Proposed meta-data attributes for all NIST-ITL
  200X xml tags
• _at_Tag of type string Example2.02
• _at_TagGroup of type integer Example2
• _at_TagUnit of type integer Example3

NIST-ITL 200X Data Model

• Requirements
• A parent object should be defined to allow
  inheritance of attributes and sub-properties
• Should follow the concepts of the NIST-ITL2000
  EDI model
• Required Header information encompasses the
  records Equivalent to Type 1 record
• A mandatory person (subject) record (type 2)
• Optional biometric records (types 3-18(?))

5
NIST-ITL 200X Data Model

• Requirement Continued
• The data model must, at a minimum, define XML
  tags for all required fields of the NIST-ITL EDI
  format.
• The data model must be extensible to allow user
  defined tags, and user defined organization for
  that data.
• The data model must use tag names that conform to
  the ISO naming convention standard
