X.400 Body Part: ODA
MIME Content-Type: application/oda
Conversion: None
Comments:
The ODA body part is defined in the CCITT document T.411 [T.411],
appendix E, section E.2, "ODA identification in the P2 protocol of
MHS"
An abbreviated version of its ASN.1 definition is:
oda-body-part EXTENDED-BODY-PART-TYPE
PARAMETERS OdaBodyPartParameters
DATA OdaData
::= id-et-oda
OdaBodyPartParameters ::= SET {
document-application-profile [0] OBJECT IDENTIFIER
document-architecture-class [1] INTEGER {
formatted (0)
processable (1)
formatted-processable(2)}}
id-et-oda OBJECT IDENTIFIER ::= { 2 8 1 0 1 }
Mapping from X.400 to MIME, the following is done:
The Parameters.document-application-profile is mapped onto the MIME
parameter "profile" according to the table below.
Profile OBJECT IDENTIFIER
Q112 { iso (1) identified-organization (3) ewos (16)
eg (2) oda (6) profile (0) q112 (1) }
