Currently almost 11,000 resources available through Organic.Edunet
15 interconnected repositories from 13 countries
Resources appropriate for school & university level, as well as vocational education & training

more than 152,000 visits from 192 countries
468,000 page views more than 124,000 unique visitors mostly new visitors / 75% search traffic

AN EVOLVING NETWORK
Expansion of network in three phases so far
1.Phase 1: The Organic.Edunet project (2008-2010)
2.Phase 2: The related projects (2009-now)
3.Phase 3: The new collections and affiliated content providers (2010-now)
PHASE 1 – THE ORGANIC.EDUNET PROJECT PARTNERS
Eleven (11) interconnected repositories Content providers include
Institutional repositories (e.g. university repositories)
Schools (e.g. Rural Wings) Associations (e.g. Ecologica) User communities (AGROASIS) Archives
Almost 10,000 metadata records provided
PHASE 2 – PROJECTS RELATED TO ORGANIC.EDUNET
Four new interconnected repositories Organic.Balkanet training curriculum (about 100
records) CerOrganic training curriculum (about 300 records) ProdINRA (about 2,000 records) TrAgLOR (Turkish Agricultural Learning Objects
Repository) (about 300 records)
Material related to vocational training and higher education
Multilingual metadata Two existing repositories will be enhanced
The Miksike collection on organic agriculture The Spanish repository on organic agriculture

PHASE 3 – NEW COLLECTIONS & AFFILIATED CONTENT PROVIDERS
6 new collections: Digital Green OER Africa Green OER YouTube videos on organic Agriculture Slideshare presentations on organic agriculture Flickr photos on organic agriculture
Small collections, based on quality over quantity Manual annotation of a small number of records
THE NETWORK OF COLLECTIONS
CONNECTING TO ORGANIC.EDUNET
CONNECTING TO THE ORGANIC.EDUNET NETWORK GUIDES
Information on “How to connect” is available through a Wiki page:

CONNECTING TO THE ORGANIC.EDUNET NETWORK WORKFLOW
3 WAYS TO CONNECT TO ORGANIC.EDUNET1. Harvesting of metadata
example: existing and new collections in Confolio harvested through an OAI-PMH target existence of various sets, that may be harvested
individually Metadata records are validated and harvested
2. Ingestion of metadata example: content from social sources XML files retrieved indirectly from
YouTube/Flickr/Slideshare etc. & ingested in compliant tools (Confolio, AgLR)
Metadata records are validated and harvested
3. Creation of metadata Example: not organized collections / individuals Use of AgLR/Confolio for the creation of metadata
records Metadata records are validated and harvested
1. HARVESTING OF METADATA
Usually the easiest way of content integration
Exposure of metadata through an OAI-PMH target Validation of OAI-PMH target -> Validation
service Metadata validation -> Metadata validation
service
Metadata mapping might be required Currently manual mapping Use of (Ag)Mint is planned
1. HARVESTING OF METADATA:
WORKFLOW
1. A content provider contacts Organic.Edunet2. The appropriateness of the repository content
is checked against the Organic.Edunet Quality Criteria
3. Basic information is requested from the content provider in a registration form
4. The target is checked using the Organic.Edunet validation service
5. The metadata structure is checked against the Organic.Edunet IEEE LOM AP using the Organic.Edunet metadata validation service
6. Metadata are harvested automatically7. If mapping is needed, then the metadata
elements are manually mapped.
2. INGESTION OF METADATA
In cases where harvesting is not an option e.g. not supported by the tool, no tool available
Metadata need to be compatible with Organic.Edunet IEEE LOM AP Mapping may be required in some cases
Metadata need to be ingested in a compatible tool and probably enriched Example: The case of YouTube XML files
Content needs to meet the Organic.Edunet Quality Criteria
2. INGESTION OF METADATA: WORKFLOW
1. A content provider contacts Organic.Edunet2. The appropriateness of the repository content is
checked against the Organic.Edunet Quality Criteria
3. Basic information is requested from the content provider in a registration form
4. A sample number of metadata records (e.g. in xml format) is checked using the Organic.Edunet metadata validation service
5. Metadata are manually ingested6. If mapping is needed, then the metadata
elements are manually mapped before ingestion.
7. In case of additional content, new manual ingestion needs to take place
INGESTION VS HARVESTING
Trying to encourage content providers to enable/support harvesting of their metadata records.
3. CREATION OF METADATA
In cases where harvesting/ingestion is not an option e.g. offline collections, not digitized material etc.
Metadata records created from scratch Fully compatible with Organic.Edunet IEEE LOM
AP if a compatible tool is used (AgLR / Confolio) Mapping is needed in case of APs other than
Organic.Edunet IEEE LOM.
3. CREATION OF METADATA: WORKFLOW
Non-digitized content
New contentContent locally
stored (e.g. hard disk)
Metadata Annotation Tool
1. Types of Content
2. Creation of metadata
3. Validation of metadata
4. Publication through
Organic.Edunet Web portal
ORGANIC.EDUNET IEEE LOM AP & ONTOLOGY
THE ORGANIC.EDUNET AP (1/2)
Based on the IEEE LOM AP, standard for describing educational resources
Slightly modified in order to match better the annotation of agricultural educational resources Selection of metadata elements Changes in the status of elements (e.g. mandatory) Introduction of required extensions
Multilingual AP: Currently available in 16 languages, including Arabic, Chinese & Hindi
Recently updated to a new version, reflecting the requirements of the Organic.Lingua EU project
THE ORGANIC.EDUNET AP (2/2)
The new Organic.Edunet AP is available at:http://wiki.agroknow.gr/organic_lingua/Organic.Edunet_Metadata_Application_Profile
THE ORGANIC.EDUNET ONTOLOGY
A conceptual model useful for classifying learning materials on the Organic Agriculture (OA) and Agroecology (AE) domain
Used in the Organic.Edunet web portal for the semantic search
Recently revised in the context of the Organic.Lingua project
ORGANIC.EDUNET-COMPLIANT TOOLS
1. Confolio Repository Tool Used by the Organic.Edunet consortium content providers as well
as by some of the new ones Folder-based organization of records Integrates the previous Organic.Edunet IEEE LOM AP (v2.0) Multilingual user interface – currently available in 17 languages
2. Agricultural Learning Repository (AgLR) Tool A tool developed by Agro-Know to support new content providers Integrates the latest Organic.Edunet IEEE LOM AP (v3.0) Will integrate the latest Organic.Edunet ontology Supports automatic translation of metadata records (Title,
Description & Keywords) Collection-based organization of records Multilingual user interface – currently available in 10 languages
ORGANIC.EDUNET – THE TOOLS
THE ORGANIC.EDUNET CONFOLIO TOOL
THE AGLR TOOL
ABOUT THE TOOLS
All repository tools that can expose metadata through an OAI-PMH target can be used Metadata will be automatically harvested, after
they are mapped to the Organic.Edunet metadata AP
Repository tools that cannot expose metadata through an OAI-PMH target can also be used Metadata will have to be exported and then
ingested to a repository tool capable of exposing metadata through OAI-PMH
ORGANIC.EDUNET IS CURRENTLY WORKING ON…
1. MULTILINGUALITY
Automatic translation tools to be integrated in both AgLR and Web portal
Work by XEROX (SMT) and CELI (CLIR), adapted in the agricultural sector
Automatic translation of Title, Description & Keywords
Additional services will be used in case of languages not supported by the aforementioned tools
2. USER ENGAGEMENT
User Generated Content widget developed by K-C
Users allowed to contribute their own content (metadata) using an easy-to-use form
This content includes suggestions for new resources and revisions/translations of existing ones
3. EXTENDING THE NETWORK
Discussions with new content providers From EU, India and Africa
Revisions in the content integration workflow Revision of the quality criteria Definition of the scope of the network
