Happens with latest source.

Input:

FOO DEFINITIONS ::= BEGIN IMPORTS MODULE-IDENTITY FROM SNMPv2-SMI; fooMIB MODULE-IDENTITY LAST-UPDATED "200006270000Z" ORGANIZATION "Carrots Inc." CONTACT-INFO "Bugs Bunny" DESCRIPTION "Testing" REVISION "200006270000Z" DESCRIPTION "1 2 3" ::= {iso(1) member-body(2) us(840) 802dot3(10006) snmpmibs(300) 43 } fooObjects OBJECT IDENTIFIER ::= { fooMIB 1 }

Output (smidump --format=mosy FOO.my):

fooMIB snmpmibs.43 %n0 fooMIB module-identity fooObjects fooMIB.1 %n0 fooObjects object-id

The ancestry of snmpmibs is clearly stated in the input, but does not appear in the output.

I have access to a mosy descendent (still called mosy) that outputs

fooMIB 1.2.840.802.10006.300.43

(Rest of output is the same)

I don't think that smidump should necessarily produce identical output, but it ought to be possible to re-create the object ID.
