General Information

SCOPE     This page contains information about the registration process and configuration management.

APPLICABLE DOCUMENTS     Documents can be obtained through the NITF Register Library.

DEFINITIONS     Acronyms used in this page.

  • RE           -     Registered Extension
  • RETAG   -     Registered Extension unique extension type identifier
  • CE           -     Controlled Extension
  • CETAG   -     Controlled Extension Tag unique extension type identifier
  • DES        -     Data Extension Segment
  • GWG       -    Geospatial Intelligence Working Group
  • NGA        -     National Geospatial-Intelligence Agency
  • NTB        -     NITFS Technical Board
  • TRE        -     Tagged Record Extension
  • Registered Extension (RE).  Those tagged record extensions for which the extension type identifier (six character RETAG field) and the user-defined data (REDATA field) structure is registered with the NTB.   The user-defined data (REDATA field) structure is not controlled by the NTB.
  • Controlled Extension (CE).  Those tagged record extensions which are submitted for approval by the NTB and are then maintained under formal configuration management control.  Both the extension type identifier (six character CETAG field) and the user-defined data (CEDATA field) structure is under configuration management control.
  • Encapsulated Extensions.  Each encapsulated extension must be in its own DES and follow the DES structure in table A-9 of MIL-STD-2500C.  Only those extensions which are accepted and registered by the NTB should be used.
   

REGISTRATION     TRE's, DES's, and Field Values must be registered with the Geospatial Intelligence Standards Working Group (GWG) NITFS Technical Board (NTB) before use within NITF files.

Registrar     The National Geospatial-Intelligence Agency (NGA) is the designated registrar.  The NITFS Technical Board (NTB) is the designated Focus Group (FG) for approval of all NITF registration items including TRE, DES, and Field Value activities.  The Joint Interoperability Test Command (JITC) serves as the executive agent to NGA for oversight of registration activities and maintenance of the register.  Contact us for registration questions.

Developmental Procedure:

  1. Submit to NTB for approval/registration if experimental/under development.
  2. If final form, submit for approval/technical review.
  3. Be prepared to have implementation lifecycle, maintenance guidance documented, and suggested test/implementation criteria available.
  4. Upon approval by NTB, register on JITC website along with copies of documentation.

Registration Submissions Must Contain:

(Note: Before using on-line submission, implementers and acquiring agencies should contact the NTB registrar to identify the current issues regarding the tagged record extensions and associated documentation applicable to their specific requirements.)

CONFIGURATION MANAGEMENT:     The NGA registrar exercises configuration management control of the register.  The register identifies the approved issue(s) and version(s) of tagged record extensions and associated specifications and documentation allowed for use within NITFS.  Although another agency may be the proponent, author, and/or configuration manager of tagged record extension specifications and documentation, only those issue(s) and version(s) identified and authorized in the register managed by NGA are allowed for use within NITFS.

TWO-YEAR REGISTRATION PERIOD OF 'RE':     Nominated RE will be recorded in the 'Register' upon approval by the NTB.  At that time, an RE expiration date (typically two years from registration) will be established by the NTB and recorded.  An RE(s) proponent may submit a request for registration renewal to the NTB, or a request for the RE(s) to become "Controlled," prior to expiration of the tag's registration.  Otherwise, the RE(s) will be marked as "expired" in the Register.
