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

5. 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!
                                                   

6. 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

7. 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

23. 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
