Interesting federation article that mentions developer interest in SPML. The
SPML reference is near the bottom of the article.

Today's focus:  SAML tops federation projects survey

Dear jbohren@opennetwork.com,

In this issue:

* Results of Ping Identity's survey of federation projects
* Links related to Identity Management
* Featured reader resource

FREE WHITE PAPER: CONVERGENCE AT THE NETWORK EDGE: FIVE
PREREQUISITES OF THE NEW MULTISERVICE EDGE PLATFORM

This white paper presents a closer look at five key attributes
for successful convergence, as well as providing additional
background on why simple evolution of today's routers, WAN
switches, Ethernet switches, and IP services platforms won't be
sufficient for next-generation converged network architectures.

Today's focus:  SAML tops federation projects survey

By Dave Kearns

Last issue we looked at some of the responses that Ping
Identity, sponsor of the SourceID Web site, received when it
recently surveyed folks who downloaded its open-source Liberty
Alliance tool kit. Ping wanted to find out more about the
downloaders' federation projects. While there weren't many
surprises in the survey results (e.g., more than 50% of the 157
respondents were with U.S. companies and almost three-fourths
were from English-speaking countries), the results to questions
about standards and protocols might raise an eyebrow or two.

When asked about the priority of federation protocols, it wasn't
surprising that the Liberty Alliance protocols out-polled the
WS-Federation protocol (favored by IBM and Microsoft) since the
respondents were specifically those who downloaded a Liberty
Alliance tool kit. But even adding together those who preferred
Liberty phase II with those who preferred Liberty phase I (a
total of 42% of the respondents) they were still outweighed (at
49%) by those who favored Versions 1.0, 1.1 and 2.0 of the
Security Assertion Markup Language (SAML).

SAML is the transport mechanism for the Liberty Alliance
proposals, and one of the allowed transports for WS-Federation,
but it appears that a number of projects are working directly
with SAML and by-passing the "higher" layers of the two
competing standards.

It might be that the projects being talked about are all early
stage developments, with the SAML parts being worked on now
while the developers look to see which of the two competing
standards will emerge with an edge - or, perhaps, a
consolidation or merger might occur with one standard being
created from the two we currently have. If you think that's a
likely scenario, then it would be wise to put off any
development at that upper level until the parameters of the
eventual standard begin to take shape.

Another of the survey questions asked downloaders what
additional protocols were "of interest" to them vis--vis
federation. The big winner there was OASIS' eXtensible Access
Control Markup Language (XACML), with 49%, followed by Service
Provisioning Markup Language (SPML) at 29%, and eXtensible
Resource Identifier (XRI) with 14%. A scattering of other
protocols took 8% of the responses.

XRI could be considered a competitor to Universal Description,
Discovery and Integration, if UDDI had ever amounted to
anything. It's to be the output of an OASIS Technical Committee
and purports to be a Uniform Resource Identifier (URI) scheme
and a corresponding Uniform Resource Name (URN) namespace for
distributed directory services. We'll take a closer look at this
in an upcoming newsletter.

Where XRI is involved with finding resources, XACML is all about
accessing resources, or perhaps protecting resources. XACML,
language for the expression of authorization policies, should be
looked at by anyone working on an SAML (framework for exchanging
authentication and authorization information) projects while XRI
should be in the toolkit of those with provisioning (i.e., SPML)
projects in the works. These protocols shouldn't be developed -
or developed to - in a vacuum. Without interaction among them
all (and that includes Liberty and WS-Federation) it's going to
be difficult to get beyond the experimental phase and into real,
working federation projects.
