[plt-scheme] dissapearance of "dot-scheme"

I may need to call a single hook in microsoft access in the future.  I
assume thats what the ".net" thing is about.  So I did a web search on
".net" and scheme, and found references to "dot-scheme" being ".net"
for plt, however I could not find any download.  Does it still exist?
