How can I create a hierarchical collection with CMDI?

Link from the parent .cmdi file to the child .cmdi file with a ResourceProxy that has the ResourceType Metadata.

The recommended profile to use for collection description is clarin.eu:cr1:p_1345561703620 (“Collection”).

All files of this example collection can be accessed and explored via http://infra.clarin.eu/cmd/example/collection/

Notice that this example is based on CMDI 1.1. The same principles apply to CMDI 1.2 in which hierarchies can be constructed in the same matter.
