exactly?

Nope. Well, assuming the contributing datasets haven't been modified, the content will be the same set of records. If collections supported versioning, then perhaps one day it might be possible to always return exactly the same data...

All the system I mentioned does (will do) is assoicate an LSID with a query document (and the target datasets). Resolving the LSID actually returns the query document, which can then be resolved by the DiGIR network.

...

just be hitting on the LSID (yes, one is under construction). One could imagine simply passing the LSID to another infrastructure that say, estimated potential distribution, or highlighted relevant news reports from an AP feed mentioning the species for which the query was created. ...
