1.  (LEANER)  CURRENT ITL STRUCTURE AND CONTENT

This proposal does these things:

bulletThe tag names are structure and delimiters from existing specification.
bulletEvery record, field, and subfield has a direct representation.
bulletThe order of records and elements exactly matches the existing specification.

 

PRO's CON's
Easy to conceptually understand and map XML elements to ITL-2000 elements (forward translation, and reverse translation). Complex data relationships that can be expressed in XML are not so expressed. 
Easy for existing implementations to migrate from ITL-2000 to XML (minimizing reprogramming effort). Elements are represented as a "row," not a "tree."
Does not abandon the proven ANSI/NIST-ITL standard that has been operational for many years. Does not adopt new biometric models defined by CBEFF or GJXDM.
GJXDM can be included as "user data" -- especially the content of the Type-2, User-defined Descriptive Text record. Tag names are undescriptive of content, do not conform to ISO-11179.
CBEFF can be included as an additional record type.  
All rules and data definition for elements exactly conform to the ITL-2000 specification.  
Of the four options, will create the "smallest" instance records.
