  1. Managing Learning Objects in Large Scale Courseware Authoring StudioIvo Marinchev, Ivo HristovInstitute of Information Technologies Bulgarian Academy of Sciences Cross-Media and Personalized Learning Applications on top of Digital Libraries20 September 2007, Budapest

  2. Overview of presentation • Learning Objects in Courseware Authoring Studio Architecture • Description Tool for Learning Objects • Managing Top-Down Data Workflow • Central vs. Distributed Repositories • Conclusions

  3. Learning Objects in Courseware Authoring Studio Architecture

  4. Learning Objects in Courseware Authoring Studio Architecture • Repositories • Media Server • Tools for creation and editing of different types of objects. • Authoring Studio user roles

  5. Description Tool for Learning Objects • Support creation, management and retrieval of reusable LOs consisting of DOs • Create educational metadata for LOs • Uses Digital Object Repository • Ensure authorized access • Uses Learning Object Repository

  6. Description Tool for Learning Objects - implementation • Implemented in Java Programming language • Base framework of Eclipse RCP • Uses eXist database storage engine to store locally last document

  7. Managing Top-Down Data Workflow • Bottom-up approach of courseware creation • Principles • Disadvantages

  8. Managing Top-Down Data Workflow

  9. Central vs. Distributed Repositories • Publishing information about web services and categorization rules specific to an organization. • Finding web services (within an organization or across organizational boundaries) that meet given criteria. • Determining the security and transport protocols supported by a given web service and the parameters necessary to invoke the service. • Providing a means to insulate applications (and providing fail-over and intelligent routing) from failures or changes in invoked services.

  10. Central vs. Distributed Repositories

  11. Conclusions • Focus on LOs creation and manipulation process (and tools) • The architecture of distributed large-scale courseware authoring studio is presented • Possible improvements in the Authoring Studio architecture are described
