autocreated date property

Is it possible to specify in cnd notation a date property that is  
autocreated and set to the current date and time?

Still, having an autocreated date property would be usefull.

One other property type which would be usefull would be one that  
guarrantees uniqueness among all properties of the same type/name,  
eg. when putting users into a jackrabbit repo and one wants to assign  
a unique UID.

INITIALIZE is one of the possible values of the OnVersionParent
attribute. It governs what happens to the property when its parent
node is versioned. It does not indicate anything about how the
property will be initialized upon creation.

The only initialization controllable through CND (or through the node
registration API of JR) is the setting of a static default value. In
CND this is done with the equals sign:

- my:property(string) = 'XYZ'

However nt:hierarchyNode is a special case because it is a built-in
node type that jackrabbit already knows about, and jackrabbit is free
to initialize its properties on node creation any way it wants.

For user-created node types, the application has to do the
initialization, if it is more complex than a static default.

Hope this helps,
Peeter

Then can someone explain what the CND notation for nt:hierarchyNode  
does?

http://wiki.apache.org/jackrabbit/nt%3ahierarchyNode

[nt:hierarchyNode]
- jcr:created (DATE) autocreated protected INITIALIZE

Thanks,
Steven Huey
