We had a guest presentation from Travis. See more at http://spaciousness.org/.

 

Also available is a step by step diagram of messaging in Spaciousness, the basic
use case that illustrates more general data interchange:

http://spaciousness.org/spaciousness-messaging.svg

 

Spaciousness is a graph database for recording user data in
any way that users see fit. It provides a single UI paradigm for navigating all
types of data. Where the name "Spaciousness" comes from is that it
provides a single shell for
navigating all graphs in a radial, spatial way according to the user's shifts
in attention. The goal is universal data
management. In order to do that and retain all the structure, Travis has built
this graph database where every edge is itself is a first-class document. What
Spaciousness is doing is defining a standard format for a graph edge. It will
enable all of a user's tools to apply to all of their data. 

 

Markus pointed out that it is a binary format, so it can be
very efficient. Also, in Spaciousness, everything is content-addressable. This
is like Bittorrent, which generates cryptographic hashes of content to divorce
the data from the location. This allows you to trust that you have the right
data no matter where it comes from.

 

The binary format for Spaciousness produces a fixed address
length than can be concatenated to navigate the graph. This is much better than
URL shortners, which introduce indirection and other potential problems.
Working with content addresses avoids this problem. 

 

In Spaciousness, the base paradigm wraps a BLOB in a map
that links other metadata, such as an icon and a scaling algorithm so  you
can see a representation quickly. 

 

In Spaciousness, users can interface via a graph server. A
sender can upload a graph with a send predicate. The message itself is an edge
document. The recipient does a query for graph edges with the send predicate.
The receipient gets the edge and dereferences the content address to get the
actual body of the message directly from the sender.

 

Travis's goal is to bring content addressability to the
world of user-centric data management, so a user can manage all of his/her
data.

 

The code is on BitBucket and linked to from
baseparadigm.org. It's not stable yet. Travis believes he's about 100 hours out
from the baseparadigm code base being stable. By Q4 2012 he plans for it to be
ready and stable.

Travis is interested in XDI because it's a binary format,
and XDI is a human-readable text format. This has various uses, such as
scripting. 

 

Spaciousness.org has a form to enter information to get
updates.

***** NEWS & UPDATES *****

 

--- Markus gave an update on the demo server

 

https://wiki.oasis-open.org/xdi/IdTrustProposal 

http://108.166.94.39/

 

Markus deployed OpenXDI components (oxServer, oxGraph, OxTestTool), as well
as the Project Danube XDI
Squared (XDI2) server there, and sent an email to the list. XDI TC members who would like access to
the server should contact Markus.

 

We then discussed a domain name for the server. We'd like
to use an OASIS domain,
e.g. under the oasis-open.org or oasis-idtrust.org domain.

 

# Drummond will emaill Robin Cover about setting up http://xdi.oasis-open.org.

 

--- Drummond, Phil, Kari, and Markus reported on insights
coming out of XDI dev meetings at Kynetx this past week.

 

Kari explained that she is working on a mobile personal
informatics app that has some reasonably advanced modelling patterns in it.
They were an excellent test of the proposed XDI multiplicity and dictionary
semantics. 

 

 

***** DECISION POINT QUEUE REVIEW *****

 

We still need to complete the prioritization of proposals
on the wiki. Drummond has added a page to track issues that do not have full
proposal pages yet:

 

  https://wiki.oasis-open.org/xdi/XdiPendingIssues

 

 

---- HTTP PROPOSAL

 

# Markus will add the Category links for the page he
created.

 

---- FILTERING ON VALUE

 

Mike said that this is turning into an important use case,
so he plans to submit a proposal page about it.

 

 

***** DECISION POINT FOR THIS CALL *****

 

We reviewed the discussion from last week, which still
needs to be documented per the action item for Markus above.

 

 

***** NEXT CALL *****

 

Drummond will be in London but is going to try to arrange
to stil be available for the standard call. He will send email to the list if
it needs any time adjustment.
