This proposal does these things:
| The tag names are textual descriptions from the existing specification. |
| Every field with a numeric tag in the existing spec has an XML representation here. |
| Every subfield in the existing spec has an XML representation here. |
| The order of records and elements exactly matches the existing specification. |
| Use of elements is maximized, of attributes minimized. |
| 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. | Has longer tag names than the "LEANER" proposal. |
| CBEFF can be included as an additional record type. | Tag names cannot strictly conform to ISO-11179 and exactly mirror the text descriptions provided by ITL-2000. |
| All rules and data definition for elements exactly conform to the ITL-2000 specification. | This is a proposal, not yet a broadly recognized body of work like GJXDM or CBEFF. |
| Tag names conform partially to the ISO-11179 naming conventions. | Existing GJXDM or CBEFF applications would have to make accomodation (wrapper?) for this model. |
| Schema will have to be developed from scratch. | |
| Needs namespace qualification. | |
| May be difficult to integrate in an enterprise or distributed environment. | |
