It does these things:
| The n: prefix is namespace for NIST-ITL extensions to the model |
| the j: prefix is namespace for GJXDM data elements |
| Some elements from the model have been removed. |
| The Type-09 record example is probably an illegal mix of n: and j: element |
| All of the necessary NIST-ITL extensions aren't yet represented by this example. |
| PRO's | CON's |
| GJXDM is now widely embraced by the criminal justice community as a preferred XML data representation model. There are over 40 projects in justice and law enforcement committed to use GJXDM. | Abandons the structure of a well-understood ANSI-NIST standard, adopting a largely-unproved model -- unproved, especially for the representation of biometric data. |
| Increasing familiarity with GJXDM will make it easy for new implementers to understand and implement biometric exchange using GJXDM. | Will be conceptually difficult for those familiar with ITL-2000 to understand. Although ITL and GJXDM elements have many one-to-one correspondences, the arrangement and sequence of elments are very different. |
| GJXDM conformance is today a requirement of many federal justice grants. | Will be difficult to migrate (reprogram, or translate) from existing implementations. |
| Complex data relationships are expressed, leveraging the power of XML. | In most cases, the ITL-2000 textual definition of elements is much more precise than the GJXDM element definition. |
| Most ITL-2000 elements can be readily mapped to GJXDM elements, and the remainder can be added by extension. GJXDM can add elements in future versions. | GJXDM will introduce new content and data elements not part of the ITL-2000 standard. |
| GJXDM user data will fit neatly into a structure that is primarily GJXDM to begin with. | "Extension" will be required to incorporate existing ITL-2000 content that is undefined by GJXDM. |
| Tag names conform to the ISO-11179 naming conventions, and are universally unique across multiple organizations. | Has longer tag names than the "LEANER" proposal. |
| CBEFF can be included by extension. | Does not adopt the biometric model defined by CBEFF. |
| GJXDM is a product of extensive effort by the Georgia Tech Research Institute. It is supported by existing schemas, and a toolset for generating subset, extension, and proxy schemas. | |
| GJXDM has a a namespace which is increasingly recognized by the justice user community, and used for defining other transmission packages. | |
