    [ https://issues.oasis-open.org/browse/CAMP-196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=60359#comment-60359 ] 

Tom Rutt commented on CAMP-196:
-------------------------------

I would like to point out the single case in our Model which could cause difficulity if we allow the consumer to change the link attribute of a collection:

The assembly resource has a component_collection attribute (down pointers) and the component resource has an assembly_collection attribute (up pointers).

To add an existing component to another assembly the consumer would have to (in separate http invocations) update the links in both a down pointing collection resource and a different up pointing collection resource.

Between these two invoctions, the system state is out of synch.

It could introduce inconsistencies in cases of http failures.

> The resolution to issue 192 has the links attribute of the collection resource as Mutable true.
> However it does not make a requirement for it to be consumer mutable true or false.
> In cases of shared components, the administrative user may need to update the collection member links
