project objectives
Project objectives

Technology:Development of an interface technology and methodology to make Internet information resources accessible through FIPA-compliant agent interface.

Prototype:Development of a library agent service.

Strategy:

Contribute to the establishment of the Agentcities network.

what is an agent
What is an agent?

Agent:problem-solving unit, perceives and changes its environment, achieves goals,

autonomous, proactively adapts to its environment

Also a new systems design paradigm:

complex distributed systems

object oriented  agent oriented

Semantic web, Web Services, GRID

what is fipa
What is FIPA?
  • FIPA: Foundation for Intelligent Physical Agents
  • International organization registered in Geneva (1996)
  • Aims at the development of software standards for interoperable heterogeneous agents and agent based systems
  • Members: key multinational IT companies, telecom companies, important universities and research institutes
  • Four meetings annually
what is agentcities
What is Agentcities?
  • Global initiative to create a world wide network for agent based services
  • Composition of dynamic, intelligent and autonomous services
  • Agent technology, Semantic Web, UDDI service repository, eBusiness standards, GRID
  • Distributed testbed
  • EU FP5 project, pattern for EU FP6 Integrated Projects
what is the role of this ikta4 project in this
What is the role of this IKTA4 project in this?

The project’s own objectives

methodology for interface technology, development of tools, prototype application

Integrated project (FP5, FP6)

national project - EU project – Agentcities Task Force

Dissemination of the technology on national level

project partners

Connecting to W3C’s work

agents and web services working group

phases of the project
Phases of the project

Setup agent platform

setting up agent environment, assessment of application requirements, design of the functionality of the prototype application, deliverables: technical document and an operating platform

Elaborate technology and methodology

FIPA standards, agent wrapper, deliverable: system plan serving as a technology guide

Prototype systemlibrary application, testing of interface technology, deliverable: prototype system

steps of the implementation of the library agent
Steps of the implementation of the library agent
  • Selection of interface towards the existing system
  • Ontology design and specification
  • Ontology code (RDF, DAML+OIL, Java)
  • Implementation of the wrapper
  • Implementation of agent logic
  • Testing the prototype system
  • Integration with other agent services
selection of the interface
Selection of the interface

Libraryapplication

GUI

  • No digging in the UI
  • No direct data access
  • Utilise existing application logic

ontology design
Ontology design
  • Concepts from
    • real life scenario (detail)
    • protocol specification (simplify)
    • value added services (define)
  • Formats:
    • FIPA spec-like document
    • Protégé project
    • RDFS, HTML, Java code
methodology architecture
Methodology: Architecture

Code intelligence

Extend ontology

Wrapper agent

Web service

FIPA ACL

Agent: combined service

Client agent

SOAP

Wrapper agent

Web service

GUI

Generate wrapper ontology

Generate SOAP call

Generate test client (for the wrapper)

WSDL
