Subject RE: Renaming node property
Date Thu, 17 May 2007 06:27:18 GMT
We've found Node type modifications a little tricky to resolve.

If you're changing a property name from X to Y then one solution is to:

 * export the affected workspace(s) to XML using exportsysview
 * empty the workspace(s)
 * update the types used by your JackRabbit install which can be achieved by
replacing the custom_nodetypes.xml file
 * do a search and replace in your exported XML replacing X with Y.
 * reimport.

Another alternative could be to update your type so that X & Y temporarily
co-exist. Create a script to copy X values to Y, and then remove property X.
Modify your types to remove X. This would require some simple Java code to
be written.

Hope this helps,

It depends, if the node definition allows free choice of property names you
could follow the steps that you described by deleting and re-adding it with
a new name.

But if the property name is defined by the node definition I think you're
out of luck. At least I don't think there is a simple solution.
You might be able to change the node type by removing all nodes of that type
and have some script re-add the data using the new node structure but I'm
not sure this is implemented yet in JackRabbit. So surely one of the gurus
here will correct me :-)
