ASG project asg-platform.org / ”Combine the Services” Interlock the performance-oriented grid community and the application-services-oriented W3C-world using the advantages of - Open Grid Service Interface - Web Service Description Language and -Web Service Resource Framework to develop an Open Platform for adaptive services discovery, creation, composition, and enactment with business-oriented Quality of Service functionality = Adaptive Services Grid

ScenariosScenarios Three application areas:  Telecommunication  Car Problem Solving Service  Enterprise IT Common in these scenarios is the need to create advanced services, based on service components from different actors.

Milestone M12 Deliverables are research reports  requirements analysis results  evaluation of existing efforts  initial conceptual results

Milestone M18 The most important conceptual results have been prototypically implemented in tools integrated to build the core ASG platform. Deliverables of this milestone  research reports  prototypical tool implementations  scenarios

Work Packages: Project Management (C-0) ASG Interface (C-1) Service Discovery & Composition (C-2) Service Creation (C-3) Adaptive Process Management (C-4) Services Grid Infrastructure (C-5) ASG Development Methodology (C-6) Usability and Demonstration (C-7) Dissemination (C-D) “… to develop a proof-of-concept prototype of an open development platform for adaptive services discovery, creation, composition, and enactment.” Big picture

ObjectiveObjective Use of UDDI registry to publish Semantic Web data  for semantic-based description,  discovery  integration of web resources in a context of needs of two research projects: “Adaptive Services Grid” (ASG) and “SmartResource”

ApproachApproach Mapping of RDFS upper concepts to UDDI data model using tModel structure, which makes possible to store semantically annotated resources internally in UDDI UDDI as an enabling specification for creation of a semantic registry for web resources in general

Semantic Annotation A description of entities using Semantic Web standards A prerequisite to allow semantic discovering and integration. In the context of UDDI, an entity of the semantic annotation would be a Web Service and businesses, business services and technical information that is a target of a binding. Consider each resource entity (not just a web service) as a subject of the semantic annotation, registering, discovering, composition, enactment, integration, etc.

ConclusionsConclusions UDDI has enough support for the registration of semantically annotated resources SmartResource project can use UDDI to implement Notice Boards for registering semantically annotated resources Publishing ASG service and domain ontology to UDDI can be performed based on publishing of WSMO to UDDI Have to elaborate API to support semantic discovery of registered resources Navigable structure

Future Work Further research is needed to elaborate semantic discovery algorithms and UDDI APIs based on proposed way of storing semantics in UDDI
