Hi all!

Some of you might have noticed that I started "Community Projects" with 
the W3C semweb Education and Outreach IG, and submitted a proposal 
myself, about using FOAF-based trust networks for whitelisting email. 
And blacklisting too. 

The project overview is at 

Importantly, I want to build it using the most basic data, really 
identifying people, context-dependant trust, etc, will need to be added 
as we go. I just want to make this useful as quickly as possible.

If no-one objects, I intend to use foaf-dev as the project mailing list. 
After all, it should be the core topic of this list. Of course, I have 
other options as well, I even have a mailman install of my own, but I 
hope to engage people here, and besides, it isn't that much activity 

I've started to write some code, as plugins for Qpsmtpd and 
SpamAssassins are the main deliverables on the road-map. 

I've created some untested code, now at 
They should be functional, though, except for one little fact, that the 
trust metric is now just a random number... :-)

Chris Prather has started coding the trust module, though, and we'll see 
what we can get out of this. Chris now has write access to my SVN repo, 
we'll be accepting patches. 

I hope people will be interested in getting involved. I hope this can be 
big, I mean, we allready have like 17 million FOAF profiles out there, 
and if this becomes useful, we could persuade others to support it.
