What globally unique, persistent, resolvable identifiers do you use for datasets?

I keep confusing findability and discoverability. It seems that findability is often equated to known-item search, and discoverability to exploratory search.

Is an ontology “better” than a relational data model? “More expressive power” doesn’t always mean “better”.

Leave beacons in your code. I would have avoided a silly error if a variable named xgb_train_data would have been named, for example, xgb_train_data_filepath instead.
