General Question related to object containment
Hi all,
i am quite new to LADP and Apache Directory Server. And i really hope
you can help me with a containment question.
I have created a new Schema, which defines just two object-classes (lets
call them Product and ProductProperty).
Of course ProductProperty is a child of Product, i.e. Products consist
of ProductProperties.
Therefore i need to ensure, that instances of ProductProperty may only
be created below instances of Product.
Does anyone know how to define such rules / restrictions? Is it defined
in some RFC?
Thanks in advance, Andreas
AW: DITStructureRules (was: General Question related to object containment)
Posted by "Eternach, Andreas (EXT)" <an...@siemens.com>.
Hi guys,
I finally found a good explanatation about the DIT structure rules:
https://www.opends.org/wiki/page/UnderstandingDITStructureRules
If we would go for an implementation of DIT-Structure-Rules in ApacheDS, then the algorithm could look as follows (please correct me if I am wrong):
0. If a DIT-object is going to be created, then following steps should be performed:
1. Find the according Structure-Rule for the new objects type, if no Structure-Rule has been found, then create the object
3.a If SUP is empty, then check whether the parent object class is the DIT-Root, otherwise reject creation
3.b If a SUP has been specified in the Structure-Rule, then find the SUP-Structure-Rule. If no SUP can be found then (what to do, throw an exception, user-error, schema-error ?)
4. Check whether the SUP-Structure-Rules name-form corresponds with the new object parents object-type. If not, then user error, otherwise create the object.

Yep you're looking for dITStructureRules which constrain which structural
objectClasses can be subordinate to another structural objectClass. I
really wanted to implement this (badly) but not much time for it these days.

Yes, it was not very clear in your previous mail that you wanted to
enforce entry to be confined in some part of the DIT ( 'below' was quite
ambiguous :).

ADS does not support DITStructureRules - nor NameForms - atm. This is
definitively something we are working on :
https://issues.apache.org/jira/browse/DIRSERVER-850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
However, I don't know when it will be available...

DITStructureRules (was: General Question related to object containment)
Posted by "Eternach, Andreas (EXT)" <an...@siemens.com>.
Hi Emmanuel ,
Thank you for the reply, but I guess you are talking about object-inheritance (I was talking about object-containment).
However, the link you posted gave me some more information:
It seems that I need to define DITStructureRules.
But how to accomplish this? The Schema-Editor of the "Apache Directory Studio" does not provide the
functionality to generate DITStructureRules.
In the meantime I figured out that there exists an objectClass metaDITStructureRule.
I can create instances of this class within my schema, but its just trial and error.
Anybody has more information?
Best regards and thanks in advance,
Andreas

If those two objectClasses are related by an inheritance relation, then
there is no way you can use the child without using the parent. In order
to describe this inheritence relation, you simply define the
ProductProperty objectClass as the child of the Produc ObjectClass using
the 'SUP' keyword.

How about modeling product properties as attributes of a product? I do
not know your specific requirements. In case that you have to search for
products with specific properties, this will perhaps lead to better
response times.
