Background
Swiss Virtual Campus SVC
• Addressing Swiss institutions of higher education (IHE)
• Impulse program 2000 - 2003
– establish and promote expertise in e-learning technologies
• Consolidation program 2004 - 2007
– establish e-learning centers @ each IHE
– maintenance of products
SWITCH - The Swiss Education & Research Network
• Foundation established in 1987
• Financed by the Swiss IHE and subsidies
• Four business fields:network, security, net services, domain registration

Four Important Findings (2006)
The Swiss institutions of higher education defined a national
e-learning platform, based on open source software, as follows:
1. No immediate and need for a nationally hosted learningmanagement system (LMS)
2. Demand for a national learning object repository (LOR)with interfaces to
– open source LMSs: Moodle, OLAT, others upon demand
– commercial LMSs: Blackboard/WebCT Vista
3. Integration of the platform into existing services
– authentication and authorization infrastructure (AAI)
– audio/video conferencing, groupware tools, etc.
4. Support of the e-learning community
– national competence center and e-learning hub

Current Situation
Digital learning content production is increasing
• Distribution of content is unsatisfactory
– LMS: institutional - local - private
– CMS, website: institutional - local - private
! generally not public, not retrievable, not persistent
• Sharing of content
– classical way: «Google»
– Web 2.0 approaches
! “Community” projects
! Wikipedia, YouTube, Digg, delicious, ...
– repositories
! Merlot, Ariadne, CAREO, LORnet, EdNA, ...

Goals and Motivation
• Reuse e-learning content
• Enhance collaboration (intra- and interinstitutional)
• Make teaching activities visible to peers and to the public
• Attract students
• Long-term archiving and distribution of content with stable URL(content lifecyle)
• Make teaching activities citable and referenceable
• Single point of entry for all kinds of e-learning contents,independently from distribution platform

Scenarios and Benefits of a LOR
• Personal content management:Lecturers can use their content in different LMS (i.e. as visiting lecturer) andlower migration cost in case of changes
• Corporate content management:Projects or working groups can share common resources and deploy themin different LMS’s
• Distributed working groupscan collaborate and build contents for common courses
• Institutions with one ore more LMScan manage their content independently from the LMS presently used
• Inter-institutional curriculacan use a common content platform with the LMS provided by theinstitutions
• National and international synergies:The exchange of learning material is being supported
