Hi Jose,

interesting topic. I'm looking forward to your talk. 

When you are talking about the "RDF equivalent of XML-SIG" you might want to
mention the Semantic Web Publishing Vocabulary - Version 2 as related work.
SWP-2 gets pretty close to XML-SIG by also using digests to sign several
resources/graphs at once.

See:

SWP-2 RDFS schema: http://www.w3.org/2004/03/trix/swp-2/

SWP-2 signature example:

e-Example.trig

Other stuff about Named Graphs: http://www.w3.org/2004/03/trix/

I'm also planning to give a lightning talk at the SW-IG meeting, talking
about the current developments around Named Graphs. And I was planning to
mention the signature stuff as well. So, maybe we should somehow coordinate
our talks?

Chris

Betreff: Proposed TP presentation: RDF-SIG

Hi folks,

If there are still slots available for presentations during the SWIG
TP meeting, I'd like to have one to talk about RDF-SIG, applying
XML Signatures to RDF.

In this short presentation, I'd like to give an overview of some
issues and solutions that can arise when signing RDF documents. 
I'll present a way that this can be done with standard detached 
XML-SIG signatures, PGP, XKMS, SPARQL, and XPointer, in comparition 
to the current > proposal to use FOAF and plain PGP.  I'll then raise 
some points on why I feel it is important to have an RDF equivalent 
of XML-SIG and discuss what parts of the wot RDF schema may find their
part into this.

Note that I'll mention RDF C14N, but that my presentation is focused
on showing one way on how the different pieces, including RDF C14N,
can be used together. Other people are already working on RDF C14N
and doing a good job.

If my presentation proposal is accepted, is it possible to know in
advance which day I will be presenting? I have another meeting during
the SWIG f2f so I can only attend one of the two days (whatever day it
is). If this is to be decided during the f2f, it's ok with me too.
