Subject: [dsml] Fwd: DSML is still important
All,
I would like to suggest a call or meeting in the next couple
of weeks to discuss DSML next steps. There was a lot of discussion last week at
the Open Group DIF meeting about the possible future of Directories and the
emerging Web Services technologies. I have attached Dave's latest newsletter and
it is a good call to action. I am not sure that taking on unfinished LDAP work
is the right activity, but there is certainly work to be done.
What do folks think?
Talk to you soon,
Winston

It was Burton Group analyst Mike Neuschwander who said that. He's wrong, and I'm here to tell you why. Mike seemed to imply that the work of the Security Assertions Markup Language (SAML) committee had overtaken the work of the DSML folk. In one way, that's true. I, along with a number of others, had urged that the DSML people should concentrate on new opportunities for the directory rather than spin out an XML replacement for Lightweight Directory Access Protocol. We suggested that an XML gateway to Lightweight Directory Access Protocol (LDAP) would be sufficient. We just didn't have the votes. The DSML committee went on to do yeoman work in restructuring the best parts of LDAP into an XML jacket - DSML Version 2 is an excellent bit of work. But business people wishing to get on with the authentication required to implement the various activities lumped together as "Web services" needed a cross- platform specification that at least started the journey on the path towards the Holy Grail of Webwide single sign-on. To that end, a group of like-minded people formed the SAML committee and delivered a well-designed initial specification (see the previous issue of this newsletter for more information). So DSML won't be the glamorous front-end for Web services. It nevertheless has a great looking future as the preferred method of interoperability among directories - and other identity storage mechanisms. We've pretty much gotten all of LDAP Version 3 (at least, all the parts we want to keep) into DSML Version 2. The next step should be to take up what appears to be the abandoned work of the various Internet Engineering Task Force LDAP working groups and incorporate their accomplishments into an upcoming DSML spec. In particular, the LDUP (LDAP Duplication/Replication/Update Protocols) committee's work needs to be revitalized and brought into the DSML arena. I had the chance to speak with LDUP co-chair Chris Apple during the recent Catalyst conference and he's adamant that the work being done by the LDUP group needs to continue. I couldn't agree more. We need standardized ways to handle duplication and replication of data if we are ever to achieve truly federated systems. No one believes that a single directory service will emerge as a de facto standard any time in the foreseeable future, so those systems we are using need to be completely interoperable. But XML is the wave of the future, and the DSML group needs to work to see that all things directory related are covered by either a single specification or, at least, related specifications. There will not be an LDAP Version 4. There will be a DSML Version 3. It's time to move all development into the DSML group. _______________________________________________________________ To contact Dave Kearns: Dave Kearns is a writer and consultant in Silicon Valley.
