  2. Agrega Autonomous Communities

  3. AgregaWhat are itsobjectives • To promote, unify and set a standard reference • To generate a repository of digital educationalobjects • To create a technological environment for the contents Theprojectisfocusedonthecreation of a federation of repositorieswhichmustallowto share thestandardisedcontents.

  4. Agrega Project team Project Direction Project Development Experts/Users Group Autonomous Communities

  5. Agrega ThePlatform is a platform of digital objects which includes 18 federated nodes, one per Autonomous Community plus another one located at the CNICE / Ministerio de Educación in Spain.

  6. Agrega LearningObjects • This repository deals with standardised educational digital objects: • Each node has its own repository with contents packaged following the standard SCORM 2004, SCORM 1.2, SCORM “Moodle” and IMS-CP. • The tagging information is stored following the standard LOM v.1.0 in Spanish (LOM-ES). • All content searches are done with a federated system based on the specification “Simple Query Interface” (SQI). • There is also a Interoperability Interface - IMS-DRI, OAI-PMH.

  7. Agrega Key issues • Creation of a federation of nodes • Management of digital educational objects following standards • One specific site per CCAA plus Administration (CNICE/MEC) • Users to manage the contents using productivity tools • Interface and functionality off-line and on-line • All these interfaces achieve WAI-AA and are multilingual

  8. Agrega Maincharacteristics • Develops a Services Oriented Architecture (SOA), distributed in interoperable Web Services components. • Open Source tools and technological developments licensed as GPL-GNU. • Generated content licensed as Creative Commons - Attribution-Non-Commercial-Share Alike Spain

  9. Agrega Maincharacteristics • Central node + autonomous nodes. • Management of all kind of web used contents: simple or compound objects. • Public or restricted contents distributed in the different nodes. • Content tools: packaging tool, search tool and interface. • Users can create new contents, but only authorised users can publish.

  10. Agrega Functionality User oriented: MEC or autonomous communities site • Digital educationalobjectsnode: • Interoperability interface IMS DRI • Content search SQI • Content storage SCORM 2004 • Content management

  11. AgregaInteroperability Access to Repository • Packaging:SCORM2004 • Tagging:LOM-es • Identification: Unified catalogue identicator / persistentURL • Search: SQI • Interoperability: DRI • Harvesting: OAI-PMH/ DC The System represents other nodes or “harvesters” like Google / OAI Allnodes are thesame, are federated, operatebetweenthem and the Internet accordingtostandards

  12. Validator Previews Basic tagging tool Search engine Agrega Tools • Packaging tool • Manages digital objects according to standard SCORM2004 • Advanced • Basic • Tagging tool • Tags digital objects according to standard LOM_es • Advanced:all fields • Basic: compulsory and basic fields to describe the object • Searching tool • Searches objects Online/ Offline Packaging tool Advanced packaging tool Basic packaging tool Tagging tool Advanced tagging tool All tools are oriented towards (1) productivity (2) minimise creation / aggregation/ desaggregation time of digital educational objects (3) taking into account the different user profiles.

  13. AgregaActors The system manages actors and profiles.

  14. AgregaPre-production and production • Pre-production: HW virtual environment with Vmware up to 19 nodes; access up to 235 usuarios • Production: HW customised environment for each node

  15. AgregaUserfunctionality • Simple searching tool • Simple packaging and tagging tool • News and FAQ tools

  16. AgregaConclusions • Creation, packaging, approval and publication according to standards • Distributed and descentralised network • Storage and search locally as well as globally • Easy management of users and profiles • Viewing and presentation environment
