We're going to need to do some more work on how we document the xDD Cyberinfrastructure as source. We are potentially pulling a pretty massive amount of value-added processing information back for claims through a combination of APIs and background processing through custom pipelines. We want to represent that at an appropriate level of granularity to establish a clear provenance trace to show how we get to particular values and pieces of information so that we avoid the whole black-box problem.
