Presentation ePortfolio interoperability framework Application Profiling and conformance testing Europass and ePortfolios

ePortfolio interoperability framework For an integrated approach in a web services architecture

The challenge A series of applications Contents Portals Communities ePortfolios Working in different environments ASP Java PHP Python Cold Fusion … Offering Different services In different languages For different cultures An integrated approach is needed!                                                    

Responses to the challenge We need to provide a seamless access to the different components of the learning / working / community environment A framework where it is easy to add (or replace) components, as needed, when needed A sustainable infrastructure Solution Common data-model IMS, HR-XML, RSS, FOAF, DUBLIN CORE… Single Sign On (SSO) and Federation of services Based on industry standards (SAML) Supported by several solutions Application 1 Application 2 Server M Server B Client browser Server A Application 3 Service Provider Identity Server Service Provider Identity Server Service Provider Identity Server Application n Identity Provider Server / Directory

Liberty Alliance / Shibboleth benefits State of the art Service Oriented Architecture (SOA) Federation of services SSO Web services Standard based Convergence Microsoft (Passport) and Sun -> for LA based products Open and extensible Lose coupling between components Extension to other tools, portals, in particular at local level, training providers, mentor - (e.g. Blackboard supports SAML) Liberty Alliance Open source implementations (SourceID, LASSO) Supported mainly by Industry (AOL / Ericsson / HP / IBM / INTEL / FT / Nokia / Novell / Oracle / SUN / Verisign… Conformance programme Shibboleth (Internet 2 Edu) Open Source implementations Shibboleth / Guanxi Supported mainly by Higher Education No real conformance programme

An integrated, distributed & cooperative learning environment through federation of services Org 2 Data Service 1 Service 2 Server M Server B Server A Org 1 Data Service 3 Service Provider Identity Server Service Provider Identity Server Service Provider Identity Server Service n Org z Data Identity Provider Server / Directory

ePortfolio Application Profiling Ceci est facilité si l’ensemble des composants supportes une même approche SSO Adapting existing specifications to your community

What ePortfolio interoperability framework? Dimension 1: Data-Model (exchange or eP parts) IMS ePortfolio -- + extended HR-XML Resume, job posting Meta-data (Dublin Core or LOM) Dimension 2 : Web Services / SSO / Service federation RSS SSO (CAS, Shibboleth, Liberty Alliance, WS* or SAML conformant products) Service federation ID-WSF support SOAP – WSDL support Dimensions 3: Semantic web, P2P, social network, digital identities Semantic web – e.g. FOAF, ontologies i-names for digital identity support (Oasis XDI/XRI) P2P architecture
