of Identities in a Web-Services World. IBM and Microsoft
have published a white paper outlining their vision of how digital
identities could be federated. The end result is a specification
called WS-Federation that will be added to the other WS specs already
published. [Source: Scott

The Truth About XML. "Contrary to popular perceptions, XML
can actually cost more than the systems many companies already have
in place, and it isn't clear that most of them need the extra capabilities
that XML offers." [McKinsey premium membership required to read

Latest Survey on Web Services. Seventy-five percent of respondents
cited integration, security, personalization (portals) and Web content
management as the most common goals of their Web services projects.
External integration with partners, order fulfillment, and payment
and billing challenges were the next most common objectives cited.

SAML Myths and Misunderstandings. As Don
Park wrote, "if you are confused about SAML, read Frank Cohen's
article. It is understandably pro-SAML, but it is a good source
of handy answers to cover your ass with."

Gray on Storage. Thanks to Phil
Windley and Tim
Bray for linking to this great interview with storage guru,
Jim Gray. Read the others' highlights, or better yet--read the whole
interview. My favorite quotes include:
Posted Wednesday, July 16, 2003 5:02:37
- Two groups start; one group uses an easy-to-use system, and another uses a not-so-easy-to-use system. The first group gets done first, and the competition is over. The winners move forward and the other guys go home. That situation is now happening in the Web services space. People who have better tools win.
- The processors are going to migrate to where the transducers
are. Thus, every display will be intelligent; every NIC will be
intelligent; and, of course, every disk will be intelligent...Soon
they will have an IP interface and will be running Web servers
and databases and file systems. Gradually, all the processors
will migrate to the transducers: displays, network interfaces,
cameras, disks, and other devices. This will happen over the next
decade. It is a radically different architecture...It's IP. The
interface is probably...some derivative of SOAP; you send requests
to it and get back responses in a pretty high-level protocol.
The IP stack does security and naming and discovery.

Encryption. Imagine being able to send encrypted email to
anyone using only their email address as a public key. No need to
obtain and verify a public key in advance. PKI has failed as an
email-encryption tool. Only a few of us use PGP. IBE could change
all that. Dan Boneh (co-founder) and Sathvik Krishnamurthy (president
and CEO) of Voltage Security
explain this new technology.

Doctorow on The DMCA and IT. From the Electronic Frontier
Foundation, Cory explains why the Digital Millennium Copyright Act
makes reverse engineering illegal in the U.S., and why that's a
bad thing for IT. Do recent changes in copyright law mean you need
to police our employees for infringement? How about your customers?
Are you responsible for traffic from anonymous users on your WiFi
LANs? And what about those new data-retention regulations? (What's
a poor CIO to do?)

Amazon.com Review of the Week:
you read only one book on Web services, this is it."
--Andrew Astor, Director, WS-I and VP Web Services,
more Amazon.com reviews.)
Speaking of books on web services...
Book Review: Web
Services--A Manager's Guide. Last month I suggested
someone write a comparative review of this new book by Anne Thomas
Manes and my latest book.
Last week, I had the opportunity to meet Anne face-to-face and to
get a copy of her book. Rather than wait, here's my own comparison.
Manager's Guide," as the title suggests, is a pragmatic guide
for managing a current web-services project. If you want to know
what works today, right down to the specific products from
individual vendors, Anne's book is the one to buy. .NET versus Java?
Which J2EE platform or UDDI-registry server? The current state of
the basic protocols: SOAP, WSDL, UDDI? You'll find the answers in
one place. As with my book, there are no code fragments or XML listings.
It's for managers, not programmers. But this book is the one to
buy for your tactical requirements.
"Loosely Coupled," on
the other hand, takes a more strategic view, and in a sense picks
up where Anne's book leaves off. I don't explain any of the
protocols. In fact I rarely mention them by name. I assume (a) you'll
learn about them somewhere else (such as from Anne's book), and
(b) they're likely to change anyway. Anne has a 30-page chapter
on "Advanced Web-Services Standards," which is where my book kicks
in. I look more deeply at the missing pieces of web services: transactions,
security, reliable asynchronous messaging, orchestration and choreography,
QoS, contracts and other business issues, infrastructure, and the
big one: industry-specific semantics. I explain the problems and
the solutions, not the specific vendors and products.
Both books cover the fundamental concepts of web services such
as service-oriented architectures. Anne, however, sees and approaches
web services as being fundamentally about application integration,
which clearly is the sweet spot today. I look at the issues regarding
inter-organizational loosely coupled web services, taking a longer-term
and more strategic view. If you're thrust into managing a web-services
project, need to ramp-up quickly, select vendors and products, and
be able to communicate with your developers, buy Anne's book. If
you need to develop a long-term web-services strategy for your organization,
buy mine. In other words: buy them both. I think you'll like the

O'Reilly on Web-Services Books. "While Web services books
haven't been a huge success yet, I believe...that the move to 'the
Internet operating system' (the world in which the network is the
computer) is one of the biggest changes we've all faced. So there's
going to be a huge upsurge of retraining to deal with that area."

SIG. (Presentation) September 9, 2003, San Francisco.
Where is today's sweet spot of web-services technologies?
I'll explore the technologies that aren't yet ready for prime
time: security, transactions, reliable asynchronous messaging,
orchestration and choreography, QoS, contracts and other business
issues, infrastructure, and the big one: industry-specific
semantics. Then I'll explain why this may not be the time
to embark on complex projects, and show you how to determine
optimum project start dates.
