| DIME
is a specification for packaging records together. DIME has the
ability to capture binary information. It also uses a fixed-length
header and pre-identified record lengths, enabling random-access
to the record of choice.
Messages that are DIME format can be attached
to a SOAP call via the WS-Attachments
specification.
Many view DIME as a successor to MIME-multipart.
It’s ability to utlize fixed-record lengths to jump ahead
is faster than MIME’s use of a separator (which needs to
be parsed for).

From Microsoft:
“DIME is a packaging mechanism that allows multiple records
of arbitrarily formatted data to be streamed together. Records
are serialized into the stream one after the other and are delineated
with an efficient binary header.
The first record in a DIME message has the MB (Message Begin)
flag set in the header and the last record has the ME (Message
End) flag set. The header also includes a fixed length-portion
that allows for the easy computation of the absolute length of
the record. Determining record lengths in an efficient manner
is important for quickly moving from one record to the next in
the data stream.”
Here is the Internet
draft for DIME.
