Thanks!

Yes. I already adjusted the default metadata templates for the metadata 
components that we developed for Triplify [1], for D2R Server [2], and for 
Pubby [3]. Each of these new default templates will replace the current 
default template (which uses the previous version of the Provenance 
Vocabulary) when a new version of the respective Linked Data publishing tool 
is released. For instance, for D2R I know they are planning a new release in 
the coming weeks.

For Pubby I don't know when a new release is planned. However, if you're 
running one of the latest versions (0.3.2 or 0.3.3) you may simply replace the 
default metadata template that comes with this release by the new default 
metadata template that you find attached. Notice, in case you have adjusted the 
default template for your server, you obviously have to adjust the new default 
template in the same way.

Cheers,
Olaf
