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

Registration Agency
Arbitrary object
description
Through DOIs resolution system, LOs are directly accessible, wherever they’re stored

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

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
