Subject: Re: [xdi] Minutes: XDI TC Telecon Friday 2012-04-27
Markus,
bitWorld is behind on a slide deck for our Personal Data Analysis project, but you can see some of the technology components here: http://www.bitworld.us/index.php?page=pda.
Our current challenge is to test the persistence of funf-collected data as XDI graphs on the phone itself. I've heard a rumor that you might have XDI wrapper code that talks to BerkleyDB. If so, this would dramatically reduce the effort needed to evaluate this approach.

Great to hear Bitworld is using FUNF, I have worked with that myself
as well and would love to learn more about what you're doing..
Also looking forward to talking more about the test tools and OASIS
server at IIW..

Following are the minutes of the unofficial telecon of the XDI TChttp://xdi.idearpad.com/62 [1]
at:
Date: Friday, 27 April 2012 USA
Time: 9:00AM - 10:30AM Pacific Time (16:00-17:30 UTC)
ATTENDING
Cameron Hunt
Kari Lippert
Mike Schwartz
Drummond Reed
REGRETS
Joseph Boyle
THE ETHERPAD LINK FOR TODAY IS:http://seed.gluu.org/oxTestTool [2]
1) WELCOME TO BITWORLD
Bitworld has joined OASIS as a non-profit member, and Cameron Hunt,
Kari Lippert, and Phil Windley will be participating in the XDI TC
under the Bitworld membership.
Cam explained that Bitworld is using FUNF from MIT, and wants to be
able to run it on mobile devices like Android. FUNF uses SQL Lite,
and thus Bitworld wants to look at writing XDI statements directly
into the SQL Lite database.
2) TEST TOOL
Mike gave a demo of the test tool developed by the OpenXDI Project.
[3][]=features
More tests are coming next week to show the following features:
http://ox.gluu.org/doku.php?id=oxserver:listoffeatures&s* how to model so that persistence and searching is optimized
Mike suggests that we run the tests on the OASIS-sponsored server.
This coming week at Internet Identity Workshop Mike and Markus and
other TC members that are attending will be able to discuss it.
3) XDI QUERY
Mike said he was still working on putting the requirements in
priority order. This may be a subject we discuss at IIW next week.
4) MODELING DEVICE IDENTITY
Drummond shared a graph pattern for device identity that Bitworld
needs. This brought up a number of questions related to device
identity, device ownership, and graph organization.
Cam mentioned that in his experience there are three key factors
involved with graph modelling:
* how to model so the presentation layer is optimized
* how to model so other automated processing (e.g.,https://svn.gluu.info/repository/openxdi/code/docs [4]
inferencing) is optimized
The goal is to minimize the model remapping between persistence,
processing, and display.
Mike explained that the reason the trend in LDAP has been towards
"flat" is that you don't want developers to need to know where there
data is, but rather to make it easy to reference.
Drummond agreed that flat is better because that way each entity
can be as independent.
Mike then explained that the OpenXDI implementation was less
concerned about keeping the graph flat because XDI makes it easier
to make extensive use of indexing.
With regard to Bitworld's design choices, Mike also suggested
looking at the oxPlus design:
specifically https://svn.gluu.info/repository/openxdi/code/docs/oxPlus/seedOverview.ppt
[5]
Mike also said that the location of the link contracts is critical.
5) NEXT CALL
Even though Internet Identity Workshop is next week, we will still
hold the next call next week at the regular time. One agenda item
will be a summary of the XDI discussions at IIW.
