Hi Ben, Joel and others,

IIRC, Ben's recollection is right. I've implemented AtomVersionHandles stuff
based on the first wiki doc/link Ben cited bellow, for the exception of
"Indexing" for search based on VHs, which was not implemented yet, AFAIK
(though AtomSpace methods that filters by VH are also available).
For details on how to use VersionHandles in the code, I suggest you to read
the related unit tests (specifically, CompositeTruthValueUTest.cxxtest and
tests in AtomSpaceUTest.cxxtest that uses VersionHandles, of course).
I don't remember someone has used this in some specific NM module yet, but
at least unit tests gave that implementation some reliability for those
(like you) decide to use it now. I think  it's worth giving it a chance ;-)

regards,
Welter
