Objectives

• Promote, unify, establish a common cataloguing, packaging and publish standard of Spanish education community learning objects

• Create a technological reference framework where learning objects can be ubiquitous accessed under different models of utilization

• Generate a common proceedings and best practices to create digital earning objects from standards.

Agrega is aimed to create a Federated Repository of Educative Digital Objects which allows teachers to share contents according to standards

• Interoperability: IMS DRI, RSS

• Harvesting: OAI-PMH

• Federated search: SQI

• Object identification: Id-MEC (PURL)

A digital repository is a storage of digital resources which can be accessed without a specific knowledge of the structure or organization of the repository

Metadata- LOM-ES

LOM-ES is a LOM application profile tailored to Spanish education communityLOM-ES is a LOM application profile tailored to Spanish education community

• General category groups the general information that describes the learning object as a whole• Lifecycle category groups the features related to the history and current state of this learning object

and those• Meta-Metadata category groups information about the metadata instance itself (rather than the

learning object that the metadata instance describes)• Technical category groups the technical requirements and technical characteristics of the learning

object.• Educational category groups the educational and pedagogic characteristics of the learning object.• Rights category groups the intellectual property rights and conditions of use for the learning object.• Relation category groups features that define the relationship between the learning object and other

related learning objects.• Annotation category provides comments on the educational use of the learning object and provides

information on when and by whom the comments were created.• Classification category describes this learning object in relation to a particular classification system.

Lessons learned

• Reload is a nice tool but has plenty of bugs. Content production is slow with Reload

• LOM-ES has been sometimes kind of hell. Finally in Oct 07 we achieved a full performing & operating LOM-ES XML binding (Castor proof)

• WAI – XHTML + CSS have been arduous but it pays!

• IMS VDEX decision for managing vocabularies, taxonomies and thesaurus has been a success!

• Teacher’s have to be involved in usability testing

• Release functionality each 4 months

23

Conclusions

• With Agrega, teachers and students will be able to:• Search a vast repository of

certified curricular content• Access from a standard

browser to every learning object existing in the repository

• With Agrega, teachers and education community will be able to:• Create new content in a

consistent way• Compose, package, reuse

already existing content• Quick deploy and

publication of content
