2 Agrega Autonomous Communities

3 Agrega What are its objectives To promote, unify and set a standard reference To generate a repository of digital educational objects To create a technological environment for the contents The project is focused on the creation of a federation of repositories which must allow to share the standardised contents.

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

5 Agrega The Platform 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 Learning Objects 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 Main characteristics 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 Main characteristics 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 educational objects node: Interoperability interface IMS DRI Content search SQI Content storage SCORM 2004 Content management

11 Agrega Interoperability 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 Access toRepository All nodes are the same, are federated, operate between them and the Internet according to standards

12 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 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. Advanced packaging tool Basic packaging tool ValidatorPreviews Basic tagging tool Advanced tagging tool Search engine Online/ Offline Packaging tool Tagging tool

13 Agrega Actors The system manages actors and profiles. ActorsDescription User All actors that are going to use the system, and they must have at least a name. Registered actor Operates inside the node where is registered, so he must have a user and a password. Administrato r In charge of administering the node: publishing news, feeds, downloads, users… Tagging actor In charge of taggings inside the system, so he is very much linked to the teacher. Teacher Might create and preview contents and store them inside the node. If the teacher is also tagging actor he might tag the contents he has created. Publisher Is related to the administrator and will be in charge of controling the publishing flow. He might also be a tagging actor. Visiting actor Is not registered in any node, so he cannot store any information inside it, and will only view public contents. System actor Generic user which represents an external node or the node itself (web service).

14 Agrega Pre-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 Agrega User functionality Simple searching tool Simple packaging and tagging tool News and FAQ tools

16 Agrega Conclusions 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
