Ok. This clarifies the situation. That is:
* when deleting target resources the default behaviour is to automatically delete links (pointing to them) as well. However
Correct.
* a specific OCCI implementation might enforce its special policies before deleting target resources.
You can enforce your own policies on Resources and Links which have been subclass (subtyped) from the OCCI model Resource/Link.
Ops, no:) What I tried to mean is the following. Taking your example: if I have a Compute (the source) linked by an IPAddressLink (the link) to a Network (the target) then
* when deleting the Compute (the source) it is natural that the IPAddressLink (the link) is deleted automatically as well, since the network link (which in fact represents a NIC) is "owned" by the compute. However
Indeed.
* when deleting the Network (the target) it might not be natural to delete the IPAddressLink as well, since the link (a NIC) is not "owned" by the network.
I see what you mean but I disagree. If you require your NIC to exist without an associated Network it is not a Link you need. You should instead model your NIC as a Resource. regards, Ralf
