I'd like to know the names of any implementation of temporal dbms available
around. If they are open source it's better for me.

so a key features of such a database is tracking the data as it changes
over time. It can be done within a relational DMBs but I know there was

I do not recall any products, but I haven't been looking for them

look up Rick Snodgrass at the University of Arizona; he has been doing
this for a few decades now.
