Besides the huge burden on the providers, subsetting is only one part of the workflow. Scientific papers need to describe the work they did including subsetting, mathematical operations, assumptions, et cetera, so merely capturing the subset information is nearly worthless. If the workflow is to be captured in a machine-readable fashion, then a service-neutral language such as (but not necessarily) the OGC Web Coverage Processing Service grammar should be referenced in the paper using a URL maintained by the author or publisher of the paper.

One approach (this appears to be the RDA group's working assumption) is for the provider to take on the burden of permanently storing queries, and from there it can issue PIDs for those queries by whatever means it has available.  Another approach is for the provider to support a query API of some kind, e.g., query URLs (think http://dataset?query=this+that+and+the+other).  This may result in lengthy URLs, but an external identifier system can be used to assign short, opaque PIDs that redirect to those query URLs.

It would be beneficial to record the relationship between these identifiers, particularly in the case when an external identifier system is being used.  The DataCite metadata schema (http://schema.datacite.org) lists a number of possibilities, but none quite fit:

This is intentionally a pretty vague relationship (as vague as publication citations, right?), whereas a cited subset has a very specific relationship to the whole.

"A IsCitedSubsetOf B" would mean that a reference to A is really a reference to B, but only a subset of B was actually used.  Note that I didn't call it IsSubsetOf, for that would bring up the same issues that IsPartOf has.  It seems important to record that the purpose of these query PIDs is for citation and nothing else.
