Eleonet aims at creating a technological system, based on appropriate DOI application profile, to facilitate the exchange
of educational content within the eLearning value chain at European level

What is DOI?
DOI® (Digital Object Identifier, www.doi.org): the international standard identifier for any Intellectual Property in a digital environment (we apply it to LOs)
A standard identifier facilitates interoperability
Example DOI: 10.1388/IndiScie49_1Prefix
assigned by the
Registration Agency
Arbitrary object
description
Through DOIs resolution system, LOs are directly accessible, wherever they’re stored
Resolving DOI: http://dx.doi.org/10.1388/IndiScie49_1

What Eleonet provides?
A common interface to allow LOs producers/aggregators to register the DOIs and to upload metadata
A search engine for final users (schools, students, teachers, universities)
A unique access point to different LO repositories

Problem: different educational contexts and curricula in EU
Approach: compare and merge Celebrate and Curriculum Online vocabularies
Result: single general, broad representation of educational context
Curriculum Online vocabulary
Celebrate vocabulary

Primary Education Primary school
Secondary Education Upper secondary school
Lower secondary school
Higher Education Post-secondary and higher education

Eleonet metadata schema
Desk analysis of existing LOM APs and SCORM conformance requirements
Comparison between different representations of educational resources at local repositories level
Use of a LOM metadata schema over national educational approaches
Market needs
Eleonet AP = LOM minimum data set + optional elements for rights information

Header with info on registrant
A DOI registration message (DOI string + Primary URL)
LOM metadata record describing single LO
DOI string brings the user to the LOs/other publisher’s page
LOM metadata record tells What is in LO, Who should use it, Who keeps copyright, Where to find it.
How it looks, LOM & DOI together?

Interface for registration of DOIs and metadata upload
Each RA involved in Eleonet develops its own interface for DOIs registration for LOs
The Eleonet web site in 4 languages presents to the users the links to 3 RAs
Eleonet provides the following registration facilities:o XML file upload o a web form for registering DOI and associated LOM metadata
The multilingual search interface will include simple and advanced search facilities
