Re: syntax for 2 dimensional multivalued attributes?
I remember such question is usually responded with
"your question is not specific to openldap. It is out-of-topic, go ask
ldap@umich.edu instead"
but I waited a night and no one responds. Either people are more tolerant
these days, or that openldap became so unimportant that no one bother to
cleanse the mailing list;)

I'm trying to store some attributes with a bit more structure than simple

I think it is much needed. I have a lot of different needs of rich-data
attribute values. Examples:
# These need special ordering rule so that you can pick out the product that
# is large enough.
myResolution: 1024x768
myFormatSize: 21mmx23mm
myDisplayArea: 15inx20in
# These too, need special ordering rule, so that you get the equipment that
# fits your shelf:
myDimension: 21x23x23
myStorageCapacity: 50x38x23
myShipmentContainDimension: 100x320x310
# This one is a key-value structure, it requires a numeric qualifier:
# it means this person won 3 Silver Medals and 4 Gold Medals
myAwards: dn=Silver Medal,ou=awards,dc=my,dc=co $ 3
myAwards: dn=Gold Medal,ou=awards,dc=my,dc=co $ 4
All these requires some overlay, and, it looks very much like IO-logic, thus
feasiable to overlay the ldap server instead of overlaying the appliation
business logic.
There seems to be a bit of a precedent in the Cosine otherMailbox
attribute, but I don't really understand what's going on
Following this lead, I looked up the attribute, and is much surprised, that
it has its own syntax. The SYNTAX 'otherMailBox' seems to be created for
just one attribute to use. I would have designed the SYNTAX to be
'labeledMailbox', and leave the meaning of the label to be defined by
attributeType.
I feel that otherMailBox designer extends LDAP only to solve his / her
problem with least system change. Perhaps when you do make your module, you
can design it general-purpose, and share it with others? Or maybe we can
work it out together :)
