OMNA PUSH Message Header Code Registry

OMNA maintains a registry of field codes that are assigned to OMA Push message headers. OMA Working Groups and other SDOs (Standard-Developing Organizations) can register OMA Push message extension headers in this registry. The assignment of field codes to the OMA Push message headers is done by OMNA.

  • A form for submitting a request may be found here.

Extension header names conform to the following structure:


FullHdrName = 'X-Oma-' [SDOName '-'] HdrName ; OMA is the default SDO name
SDOName = 1*VCHAR
HdrName = 1*VCHAR
; (RFC 5234 defines VCHAR as any visible character
; i.e. any character with ASCII value in the range
; 0x21 through 0x7E)

Header field code assignments, made by OMNA, are specified in the following table:
