Dear LDP group,

The W3C Provenance working group has recently published an updated Provenance 
Access and Query document at http://www.w3.org/TR/2013/WD-prov-aq-20130312/. 
This document is destined to become a W3C NOTE.

This document includes sections on service discovery and provenance "ping-back" 
which may be related to mechanisms you are working to specify.

The section on provenance query services 
(http://www.w3.org/TR/2013/WD-prov-aq-20130312/#provenance-query-services) takes 
account of some discussions I had with some members of your group, and in 
p[articular some exchanges from about 
http://lists.w3.org/Archives/Public/public-ldp/2012Dec/0003.html.  (The PROV WG 
has just agreed to further adjust the language so that the described RDF format 
is more clearly just one among equals.)

The section on pingbacks 
(http://www.w3.org/TR/2013/WD-prov-aq-20130312/#forward-provenance) is intended 
to provide a way for a publisher to learn about additional provenance related to 
a published resource.  We would be interested to hear from web services experts 
if they have any experience of using HTTP in this way, and if there are any 
known problems with the proposed approach.  (The PROV WG has agreed to drop the 
implied directionality in the name used and description.)

Thank you for your attention.
