AGENDA

1) XDI RDF BOX GRAPHING 

Drummond has posted a PDF file of a new XDI RDF graphing technique he developed to illustrate the nesting of $has statements, which addresses a question raised by Giovanni in the discussion of link contract structure. Drummond's PDF is at:

  http://www.oasis-open.org/committees/download.php/35421/xdi-rdf-box-graphs-v1.pdf

The discussion thread is at the following link (and its antecedents):

  http://lists.oasis-open.org/archives/xdi/200911/msg00006.html

This will probably take the entire call, but in case, we still have one holdover topic.

2) CANONICALIZATION FOR XDI SIGNATURES (HELD OVER)

Sill pending from earlier agendas:

Work on XRD 1.0 in the XRI TC resulted in a decision to drop the priority

attribute and just rely on document order for priority. Also, the use of XML

signatures was carefully profiled to avoid complex canonicalization.

The combination of these two decisions raises the question of whether XDI

signatures can also be similarly simplified. In other words, could we not

specify that XDI signatures are simply done over the XDI document in

document order, with the only normalization being the removal of all

whitespace outside literals?
