Data from Data Commons can come from multiple resources. Provide mechanisms to let users choose which of those resources are used for the returned data.
Selections might be made in advance, e.g., via prioritization of data sources to use for a particular request, or for all requests, from the list of all data sources (or at least the ones used to service the current request).
Or the user could be prompted once the data is retrieved, though this requires returning all the data from all sources.
