No, it would work similarly to how it does now but each aggregator would not hold its own cache. The cache would be centrally managed (and funded 
) and would be used by all aggregators as their data repository. Aggregators could then display a subset of the data based on any geographic or taxonomic requirement (Vertnet - only vertebrates, iDigBio - only US collections, etc.) much like GBIF-hosted portals work now. This would simplify the publishing process in that, as a provider, I would simply publish to the central cache and not to each aggregator. There could be a mechanism for publishers to decide which aggregators they wish their data to appear in - simple checkboxes would do.
