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

E.g. http://infra.clarin.eu/cmd/example/collection/collection_root.cmdi has 2 child collections:
- http://infra.clarin.eu/cmd/example/collection/collection_lrt_inventory.cmdi, this file contains in turn links to files like:
- http://infra.clarin.eu/cmd/example/collection/collection_olac.cmdi
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 1.1. The same principles apply to CMDI 1.2 in which hierarchies can be constructed in the same matter.
Below is a graphical representation (as shown by Arbil) of the CMDI file hierarchy used above as an example.
