CopperCore: An Open Source IMS Learning Design Engine by Open University of the Netherlands

CopperCore is an open-source IMS Learning Design engine developed by the Open University of the Netherlands. This community-driven project allows users to freely access, modify, and distribute the software while ensuring compliance with the GPL license. CopperCore aims to simplify the integration of IMS Learning Design in various environments without functioning as a standalone virtual learning environment. It fosters collaboration within the LD community, promoting enhanced quality and resource sharing among developers.

  1. CopperCore, an Open Source IMS Learning Design Engine Hubert Vogten Open University of the Netherlands OTEC

  2. What is Open Source? • Open Source is about: • the right to make copies of the software and distribute these copies • the right to access the source code of the software • the right to make improvements to the software • these rights are guaranteed through a license • For an exact definition and the approved licenses have a look at http://opensource.org

  3. Open University of the Netherlands (OTEC) • has been involved in the development of an learning design specification for many years which finally resulted in IMS Learning Design • is committed to providing services/dissemination but, has limited resources • the LD community is looking at us with regards to first implementations of the specifications of this complex specification • we decided to develop CopperCore, an IMS Learning Design Engine and make it available as Open Source

  4. CopperCore Development Strategy (1/2) • Why Open Source development? • out of principle, publicly funded, public access • enhance quality, code is peer reviewed by community • enhance resources by contributions of others • enables the use of other Open Source components • (governments are enforcing it by law, however not yet in the Netherlands) • Advantage for users of CopperCore • use of the code is free (access, copying, modifying) • no restrictions in usage of the code except for the GPL in case of the CopperCore • No issues about IPR when collaborating with others

  5. CopperCore Development Strategy (2/2) • CopperCore Objectives: • to provide an open source software component that can process the IMS Learning Design specification encapsulating it’s complexity for developers wanting to integrate LD in their environment • NOT to provide yet another VLE • allows integration in different environments • not indented to be used stand alone, but rather in a service or component based architecture

  6. CopperCore API’s • Provides 3 Application Programming Interfaces • dealing with administrative tasks • dealing with run-time delivery of the IMS LD specification • dealing with time dependent events • Two levels of APIs are supported • native Java, based on the J2EE framework • web services through SOAP

  7. CopperCore layered architecture

  8. The CopperCore add-ons • Clicc • very basic command line access to the administrative API • Publisher • a basic web interface allowing the validation and publication of IMS LD manifests • WebPlayer • very simple LD player demonstrating the use of the run-time delivery API

  9. presentation layer components CopperCore and other components authentication QTI component authorization CopperCore searching conferencing policy management LIP component user management

  10. CopperCore CopperCore integration: Alfanet

  11. Service Based Learning Design CopperCore integration: JISC ELF Framework

  12. How did Open Source strategy help us ? • by giving IMS LD community easy access to CopperCore, stimulating use of LD • similar we can and did use developments of others. Community building around (educational) components • we have got feedback and code proposals from others which enhanced and improved our developments • has led to cooperation with others like Alfanet, the Service Based Learning Design in JISC ELF and with Reload in Unfold

  13. Additional information • CopperCorehttp://copercore.org • Unfoldhttp://www.unfold-project.net • Reloadhttp://reload.ac.uk • The SLeD player http://ldplayer.sourceforge.net • JISC E-Learning Frameworkhttp://www.jisc.ac.uk/ • Alfanethttp://alfanet.ia.uned.es • And the stand of the Open University

  14. Why choose for Open Source Development? • Principle reasons • publicly funded projects should be publicly accessible • Practical reasons • more and more governments enforcing it by law • means of bundling and extending resources • more people working on the code • re-use of components that are available • means of improving quality by having peers reviewing the code
