March 2005 EC Presentation 5

Top Level Notions

Provide the formally specified terminologyof the information used by all other components

Semantic description of Web Services: - Capability (functional)- Interfaces (usage)

Objectives that a client may havewhen consulting a Web Service

Connectors between components with mediation facilities for handling heterogeneities

- Advertising of Web Service- Support for WS Discovery

Behavior Interface for consuming WS- Messages - External Visible Behavior- ‘Grounding’

Realization of WS functionality by using other Web Services - Functional decomposition - WS Composition

March 2005 EC Presentation 9

Conceptual Achievements (1/2)

• Establishment of WSMO within DIP– Semantic Description Framework based on WSMO– Common DIP view of the SWS world

• Towards a WSMO based SWS application methodology– Interface creation based on WSMO goals– Back end based on WSMO web services

March 2005 EC Presentation 10

Conceptual Achievements (2/2)

• WSMO orchestration (and choreography) linked to business process modelling

• Hybrid reasoning framework– WSML incorporates description logic

(e.g. OWL-DL) and deductive rule-based systems (F-Logic, Datalog)

– Algorithms also completed

March 2005 EC Presentation 11

Architectural Achievements

• DIP architecture completed– Components– Functionalities– communication

• DIP component APIs completed

WSMX

March 2005 EC Presentation 12

Implementations

• WSMX• IRS III

– WSMO compliant SWS development infrastructure – Used by tutorial attendees– Interoperable with WSMX

• WSMO API & WSMO 4J• KAON 2

– Ontology server/query engine

• Ontology editor/browser for use cases• Ontology server for use cases• Pre release WSML• Use case mockups

– EGovernment ‘Change of Circumstances’ – Banking – mortgage comparison– VISP – user centred application

March 2005 EC Presentation 13

Ontologies

• Refinements of the WSMO ontology– Tension between user web service separation and capability

based invocation

• Business Data ontology• EGovernment

– Domain ontology for change of circumstances

– Seamless UK Taxonomy

• VISP– Domain ontology

– Process ontology

• Financial– Based on IFX

• WSMO case study descriptions

March 2005 EC Presentation 14

Case Study Achievements

• Scenarios created

• Requirements generated

• Potential impact assessed

• Initial ontologies created

• Mockup prototypes created

• Links with use case communities

Aligning Implementation Plan with WSMO

• WSMO– WSMO is the framework for DIP– WP3 will contribute to WSMO

• WSMX– WSMX is the main implementation platform– WP6 will contribute to WSMX

• WSML– WSML is the ontology representation language – WP2 will contribute to WSML

• Align DIP and WSMO activities– WSMO phone conferences (WP11)– WSMO tutorials (WP14)

March 2005 EC Presentation 24

Align with OMWG

• http://www.omwg.org/• Academic and industrial initiative• Comprehensive ontology management suite• WP2 work aligned with OMWG

March 2005 EC Presentation 25

Summary

• DIP uses a Grounded Research Paradigm• Achievements on number of dimensions

– Conceptual

– Implementation

– Case Studies

– Dissemination

• DIP Workplan aligned with WSMO working group and OMWG
