another question on CompactNodeTypeDefReader

Hi Tobias,

just another question on the CompactNodeTypeDefReader, please see my CND 
file components below:

[cm:aclEntryNode] > nt:base
-cm:uid (string) mandatory copy
-cm:permission (string) mandatory multiple copy
<'1','2','4','8','16'

/* the node names of aclNode's children are the common name of the aclEntry 
Nodetype's id property */
[cm:aclNode] > nt:base
+cm:* (cm:aclEntryNode) = cm:aclEntryNode
  copy

What I'd like to have is a node hierarchy that reflects an ACL object. But 
the parser throws an ParserException saying "Error while parsing 'cm:'".
It seems that the parser doesn't like expression "cm:*", which I expect to 
tell the system "the subnode can have any name, as long as it is of NodeType 
cm:aclEntryNode".

Any advice on this?

Thanks,
Dan

Hi Torgeir,

First, thanks for responding. It reminds me of the error of using "cm:*" 
insteand of "*". This fixes my problem.

Second, I understand that your model would work well if you are to implement 
access control on multiple node types since they "mix-in" :)

My scenario is a bit different: I'd like to have a Workspace-wide acl which 
is evaluated against any attempt to access the workspace. As for node level 
access control, I intend to use special properties like "editors", "readers" 
to support low level access control.

Any suggestions?

Regards,
Dan

What about having a mixin nodetype that denotes a protected node? The 
mixin node would 0..N ace children, eg:

[nen:protected] mixin orderable
- nen:owner (string) mandatory multiple
+ nen:ace(nen:ace)=nen:ace multiple

[nen:ace] > nt:base
- nen:principal (string) mandatory
- nen:action (string) mandatory multiple
- nen:negative (boolean) mandatory

These are the nodeTypes I'm working with at the moment.
