*Discussion*

Bob attended the May 1-3 Internet Identity Workshop. Among URL-based identity projects -- which are primarily aimed at dealing with blog spam -- OpenID (openid.net) seems to be the market leader; XRI (http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=xri) is another contender. Not much of interest seems to be happening yet with InfoCard interoperability.

Bob is planning to attend a series of GEANT2 technical workshops in England, June 12-16; the eduGAIN architecture will be among the topics discussed.

Committees are forming to work on an interfederation agreement between E-Authentication and InCommon; the target date is October 1.

Steve Carmody noted that a new entity, to be called TestShib, is being developed to replace InQueue. Applications to InQueue will be shut off a few weeks after TestShib is operational, then InQueue will be taken down later this year.

Finally the group discussed workflow architectures and projects. Bob posed the question whether workflow and message technologies are two different things or two flavors of the same thing. The group's consensus was that they are two different things; Leif characterized them as separate but related, citing the XMPP-based workflow project Sluice (http://butterfat.net/sluice/) as an example. Leif also described Sluice as "dead". David asked what we could learn from that, suggesting that Sluice was too complex, too soon. He also suggested that it was a victim of the technical people being more enamored of the ideas behind it than were the prospective users -- much like PKI. Bob noted that in planning the workflow CAMP he's gotten comments along the lines of "oh, workflow, we did some cool stuff with that ten years ago." David noted that you can do scripted workflow with AppleScript, though few people use this in a sophisticated way yet. Lynn noted that BPEL seems to be getting some traction; Leif noted that it's backed by some big players. See http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=wsbpel.
