[Zope-CMF] Proxy Roles for Filesystem objects

[Peter Simmons]

Hi,

I was wondering if anyone knew of a way to give proxy roles to 
filesystem objects. Specifically we need this to allow editing of some 
vocabularies in the metadata but not others. The current permission for 
editing vocabs is Manage Portal not only will the other vocabs be 
editable but a bunch of other things if we give the user rights to 
access this.

I know we could not use the portal metadata tool to stored this stuff or 
customise the portal metadata tool and add some permissions or something 
but it seems that giving a proxy on  a filesystem python script is a 
good solution and is secure enough because the object isn't editable and 
presumably a customised object wouldn't get the proxy role and at any 
rate only trusted users would be able to do that.

Cheers,
Pete
