1. Provide a convenient mechanism for directing (ordinary) collected or declared resources to a different aggregate than the target node's catalog. One could use such a mechanism to divert resources of any type away from the catalog, so no new flavor of resource would be required. This supposes that the data associated with such resources would still be available during catalog building, to inform declaration of resources that do go into the catalog. 2. If the need is for a repository of dynamic node data, and especially if those data are expected to often not correlate directly to target-node resources, then sit down and design that thing from the ground up.
