Final system architecture

System perspectives

Take-away message (motto) Main goal is to help people with multiple credentials problem and complicated registration process. Achieved by simple, universal identity management system: D-FOAF extended with SOA.

Main goal is to help people with multiple credentials problem and complicated registration process.

Achieved by simple, universal identity management system:

D-FOAF extended with SOA.

Scenario Alice registered to the travel.com easily (possibly with FOAF profile) then she logs to the service and manage the profile travel.com FOAFRealm FOAF login(); Alice

Alice registered to the travel.com easily (possibly with FOAF profile)

then she logs to the service and manage the profile

Scenario Alice logs into music.com and games.com without new registration travel.com FOAFRealm music.com FOAFRealm games.com FOAFRealm D-FOAF Alice

Alice logs into music.com and games.com without new registration

Scenario Alice uses lot more various services (build with varius languages) with the same credentials. How to achieve this? How to make D-FOAF popular - solve multiple credentials problem? Separate implementations or unified service access method? Mobiles Java PHP .Net D-FOAF ?

Alice uses lot more various services (build with varius languages) with the same credentials.

How to achieve this?

How to make D-FOAF popular - solve multiple credentials problem?

Separate implementations or unified service access method?

Scenario Alice uses lot more various services with the same credentials. travel.com FOAFRealm music.com FOAFRealm games.com FOAFRealm D-FOAF movies.com fun.com sport.com pets.com SOA (REST) SOA (REST) SOA (REST) Alice

Alice uses lot more various services with the same credentials.

Why SOA? Fully Web oriented FOAFRealm/D-FOAF is Web appliaction Language independent Platform independent SOA Linux C/C++ JME Windows JEE .Net PHP

Fully Web oriented

FOAFRealm/D-FOAF is Web appliaction

Language independent

Platform independent

SOA Implementation – REST vs SOAP Why REST was selected? Resource oriented. Semantic Web compilant (URI, RDF) Real Web utilisation (HTTP) Simplicity and clearness ?

Why REST was selected?

Resource oriented.

Semantic Web compilant (URI, RDF)

Real Web utilisation (HTTP)

Simplicity and clearness

REST SOA - Example FOAFRealm SOA (REST) GET http://foafrealm.org/soa/alice@exmpl.org/nick POST http://foafrealm.org/soa/alice@exmpl.org/nick (with authentication information) Alice RDF RDF(with new nick)

Final system Universal Identity Management System JEE, PHP, .Net, JME implementations Backward compatibility In wider scope: solution for multiple credentials problem.

Universal Identity Management System

Backward compatibility

In wider scope:

solution for multiple credentials problem.
