Ordered list support in LDAP
Hi,
I was wondering if there is a way to support ordered lists in LDAP server,
where the order of the values is always maintained and values are presented
to the clients in the same order as specified while adding these values.
One approach could be to use the option field in the attribute description {
<AttributeDescription>::= <AttributeType> [";" <options> ] } to create
attribute subtypes which can used to tag an order to attribute values. A
client can then specifically ask for <attributetype>;N where N is it's order
number or have a way to understand the ordering of the values.
e.g.: Given an attribute, say address, which can take multiple values, while
creating such an entry, clients can define multiple values for address;1
address;2 address;3 address;4 as 4 different values for the attribute
address but also implying the order 1,2,3,4 for the values. Clients can
specifically search for address;1 or address;2 or address;3 to get ordered
list of values.
Is this a reasonable thing to do or are there better ways to implement this
feature?
Thanks,
