Hi all, AFAIK, UDDI is mainly for static registration and is not suitable for many gird scenarios. However section 5 of WS-I Basic Profile 1.1 sanctions UDDI 2.0 for Service Publication & Discovery.

When publication or discovery of Web services is required, UDDI is the mechanism the Profile has adopted to describe Web service providers and the Web services they provide. Business, intended use, and Web service type descriptions are made in UDDI terms; detailed technical descriptions are made in WSDL terms. Where the two specifications define overlapping descriptive data and both forms of description are used, the Profile specifies that the descriptions must > not conflict.

Registration of Web service instances in UDDI registries is optional. By no means do all usage scenarios require the kind of metadata and discovery UDDI provides, but where such capability is needed, UDDI is the sanctioned mechanism.

Should we exclude section 5 of WS-I BP 1.1? If so, section 1.2 Relationship to other profiles (page 4 line 114-116) should read; "This Profile extends the WS-I Basic Profile 1.1 [WS-I BP 1.1]. All requirements except for section 5 "Service Publication and Discovery" specified in WS-I BP 1.1 pertain to this Profile." However, more study is necessary for this topic, thus I also propose to start hearing several Grid projects on this questions in parallel. Let's discuss this issue on Wednesday. -- Hiro Kishimoto
