1) SPECIAL GUEST: PHIL WINDLEY

Phil
 is co-founder and CTO of Kynetx and author of the new book, The Live 
Web. He explained his interest in doing an XDI server implementation and
 using XDI together with KRL (Kynetx Rules Language). Kynetx has been 
focused on Personal Event Networks, where events can be shared against a
 set of personal devices and personal data. Being able to connect a 
collection of personal event networks, and how to do trusted links 
between them, is a good fit for XDI.

In
 particular, XDI link contracts are good for describing event channels 
and the permissions and notifications that go with each channel.

Phil
 explained that the technology that his company Kynetx brings to the 
table, KRL, fits well with the kind of rules processing required to 
efficiently process events. He said that KRL is just one choice of rules
 language -- the model he is advocating is not specific to any one rules
 language.

We
 discussed dynamic channels, which may be put up and torn down very 
quickly depending on other conditions. This fits well with modeling 
channels as data structures in the XDI graph. 

What
 is most compelling about XDI when it comes to event networks, however, 
is the ability to federated event networks at scale just like SMTP 
permits federated email messaging at scale. An example is the idea of 
"intentcasting" in VRM (Vendor Relationship Management), where for 
instance a parent travelling to Disneyland arrives and finds their 
stroller has been lost by the airline. Rather than all the work of 
renting a car, finding a store, and finding a stroller, the parent could
 just "cast" their intent to buy (or rent) a stroller, and relevant 
merchants in the area can respond. That requires a federated event 
network where the event messages have matching semantics so publishers 
and subscribers can find each other's intents.

It
 also clearly requires trust and permissions, as Phil pointed out, 
saying that "All you need to do is tweet '#macbookpro problem' and see 
all the junk you get back to understand the trust issue."

Drummond
 also mentioned a conference he had recently been sent an invitation too
 called SmartData that wants to explore ways of sharing personal data 
via "autonomous agents" who can protect the privacy of that data.

2) IDTRUST BUDGET PROPOSAL

Update.

3) OPEN SOURCE PROJECT UPDATES

Markus provided an update on XDI² ("XDI-Squared"). This is the new Java code base that he has recently packaged up and published. It is a new effort that is independent of the earlier XDI4j library (a component of the Higgins project). Supported
 features right now include a basic implementation of the XDI graph 
model, (de-)serialization, several storage mechanisms, and an XDI client
 and server. It doesn't yet have link 
contracts but Markus is going to continue to evolve it as a general 
purpose reference implementation of the specs. It also includes a set of XDI-related web tools, such as the XDI Converter or XDI Messenger.

6) RESCHEDULING WEEKLY CALL

Bill asked if the TC would consider moving the weekly call to 9AM PT/noon ET on Friday. 

#
 DRUMMOND to send an email to the list checking with everyone about 
this. If there is agreement, we will move to that call schedule next 
week.
