StoreValueOfLink
From OpenCog
The StoreValueOfLink is a form of ValueOfLink that writes the indicated Value to storage. It then returns the current Value. It has the format:
StoreValueOfLink SomeAtom PredicateNode "some key" StorageNode "some://url"
On execution, it writes Value to the StorageNode, and then returns it just as ValueOfLink would.
Dual to this is FetchValueOf, which will fetch the Value from storage, and return that.
