Can't find mod34 and OpenURL10 metadata plugins after upgrade

I’ve upgraded from 3.2.1.2 to 3.3.0.8. When I compare the plugins/metadata folder from the two versions, I see that 3.2.1.2 had 3 subfolders (dc11, mod34, openurl10), while 3.3.0.8 only has dc11. I looked on the Installed Plugins and Plugin Gallery tabs, but can’t find neither mod34, nor openurl10. Have they changed names or were they retired?
