Re: [service-orientated-architecture] Active Directory as Registry

[Todd Biske]

My gut reaction to questions such as this is, "Does it work?  If so, does it really matter whether LDAP or UDDI is used behind the scenes?"   first and foremost, you need to understand how the registry/repository is being used.  If it's used for design-time browsing of available services, the UDDI/LDAP question really doesn't matter.  No user is going to want to enter LDAP search filters or a UDDI inquiry messages.  They'll want a google like interface for finding services- enter some keywords and see what matches. Now if you're talking the run-time use of a registry/repository with system-to-system interaction, rather than user-to-system interaction, now it actually becomes an important decision.  I'll presume that run-time binding of WSDL is important in this case, so it doesn't turn into a debate of whether run-time lookups should be used or not.  This becomes a typical integration scenario.  You've got two registry options, so now you need to look at the consumer-side stack and see what it supports.  If it support both, which is going to be more work for the team developing the consumer?  What's the likelihood of a change in development platform for the consumer to where support for UDDI vs. LDAP on other platforms is important? My guess is that UDDI is going to be less work, however, I've never sat down and tried to write that code myself, so I can't say for sure.  Unfortunately, the technology industry likes to create new protocols rather than layering some constraints on a general purpose protocol.   -tb   On Oct 8, 2006, at 8:23 PM, Naren Chawla wrote: Folks --   Prior to UDDI, there was LDAP.  One could potentially evolve LDAP as mechanims for service discovery.   So what are the advantages of UDDI spec over LDAP.   More specifically, can one use Active Directory as a mechanism to register and discover services? What is the value add of using UDDI-based registry like systinet?   --Naren     __._,_.___ SPONSORED LINKS Computer software program Computer software spy Computer job Database software Discount computer software Your email settings: Individual Email|Traditional Change settings via the Web (Yahoo!
