2. © 2007 SWITCH Current Situation Digital learning content production is increasing Distribution of content –LMS: institutional - local - private –CMS, website: institutional - local - private  generally not public, not retrievable, not persistent  digital heritage of universities not preserved Content sharing and transfer: –Classical way: “Google” –Web 2.0 approaches: (technology, tools, services, way-of-thinking)  Social - networking  Wikipedia, YouTube, Digg, delicious,...  potential copyright issues –Repositories: Merlot, Ariadne, CAREO, LORnet, EdNA,... Web2.0: easy, attractive, flexible, social

3. © 2007 SWITCH Goals and Motivation Re-use e-learning content Enhance collaboration (intra- and inter-institutional) 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

4. © 2007 SWITCH Scenarios and Benefits of a LOR Personal content management: Lecturers can use their content in different LMS (i.e. as visiting lecturer) and lower migration cost in case of changes  Corporate content management: Projects or working groups can share common resources and deploy them in different LMS Distributed working groups can collaborate and build contents for common courses Institutions with one ore more LMS can manage their content independently from the LMS which is currently used Inter-institutional degrees (e.g. Master degrees at UAS, small institutes at universities) can use a common content platform with the LMS provided by the institutions I have a concept that my students frequently struggle with and need to find better ways to demonstrate it. I need an assignment for a new topic area I want to include in my course.  Establish a media library on faculty level of an institution

5. © 2007 SWITCH LOR Criteria as defined by working groups Ease of use –Publish: one-click export from LMS to repository –Retrieve: full-text search, metadata search, Google search, browse –Re-use: try it online, download standardized package Metadata –Simple metadata model (low number of mandatory tags) –Adaptable model (extensible with optional tags) –Re-use existing metadata Quality assurance –Quality of metadata (editorial department) –Quality of content (peer reviews) Access rights –Authors control access to their contents –Control levels: individual (private), group, institution, world (public) –Authentication by AAI

6. © 2007 SWITCH LOR Criteria (cont.) Federated architecture: –Possibility to run institutional repository that is part of a federation User interface –Adaptable:  simple interface with few functions  or advanced, special purpose interfaces –Support for multiple languages: en, fr, de, it Federation –International federation: possibility to cooperate with foreign repositories –LOR complies with OAI-PMH standard Extensible architecture –Flexibility to integrate special applications, e.g. manage e-tests, manage x-ray images, implement workflows

8. © 2007 SWITCH General decisions restrictions, requirements –currently, only learning objects –national level –higher education no restrictions or constraints –granularity: course, module, lesson, image, video clip, pdf-doc,... –license: creative commons, commercial,... –access rights: public, group, private –no formal quality criteria or reviewing national system based on open source software –Fedora –Meresco, PKP Harvester, Fez(?)
