Introduction

This do
cument
presents the design and specifications of the architecture of the
Organic.Balkanet services that will be deployed and offered through the
Organic.
Edunet web portal, using the content and the technologies and services
provided by MOLE platform
.



Org
anic.Balkanet will
get

interoperability mechanisms with other Organic Agriculture
Material Repositories
using

OAI
-
PMH protocol
, for this reason Organic.Balkanet will
used
Organic.Edunet Web portal
to
provide

access

to OA

learning r
e
sources residing
in MOLE

repository and will publish Organic.Balkanet learning resources through its
services.

Overall Arquitecture of

Organic.Balkanet

This section introduces

to the overall arquitecture of Organic

in order to have a
common understanting on the technologies to b
e
used.




The Organic.Edunet Web portal provides access to a federation of several
learning repositories that have multilingual, quality
-
certified content related to
the general topic areas of Organic Agriculture and Agroecology. It aims to
serve as a singl
e
-
point of access for searching, finding, reviewing, and
accessing digital educational resources around the topics of interest.



The
MOLE (Multimedia Open Learning Environment)
,
is a multimedia
info
r
mation system
developed by TUC
for managing courses, suppo
rting
learning pro
c
esses and learning communities through the Web.

MOLE
provides services for su
p
porting
learning and collaboration
, as well as
services for
course creation and ma
n
agement
. MOLE is able to support large
volumes of data as well as many paral
lel co
n
nections.



Communication Middleware

for the comm
u
nication with external repositories
that provide educational material in the subject of Organic Agriculture. This
middleware allows for the publishing of the MOLE learning resources
metadata in other O
A federations, as well as the exploitation of the content
residing in external OA repositories in MOLE courses. To achiev
e this
communication middleware MOLE provides the component

Learning
Resources Metadata Expose Module
, which implements the Open Access

Initiative Protocol for Metadata Harvesting (OAI
-
PHM,
http://www.openarchives.org/OAI/ openarchivesprotocol.html) to support
metadata harvesting of MOLE learning resources from Organic.Edunet
Feder
a
tion services. This way the metadata of learning resource
s residing in
MOLE are available from Organic.Edunet Federation making possible the
search and access of MOLE learning resources using the Organic.Edunet
services.


Next sections detail each one of these components and conclude

with the detailed
arquitectu
re of Organic.Balkanet.

Organic.Edunet
Web Portal

The Organic.Edunet Web portal provides access to a federation of several learning
repositories that have multilingual, quality
-
certified content related to the general
topic areas of Organic Agriculture an
d Agroecology. It aims to serve as a single
-
point
of access for searching, finding, reviewing, and accessing digital educational
resources around the topics of interest.

Several organisations have connected their institutional collections with the
federati
on, allowing their content to be searchable through the Organic.Edunet Web
portal. In addition, a number of user communities that are creating, sharing, and
exchanging educational resources on Organic Agriculture, Agroecology or relevant
topics, have been
facilitated by the Organic.Edunet software tools and made their
content also searchable through this portal.


3.1

Overall
Architecture
of Organic.Edunet Portal

The global architecture of Organic.Edunet is composed of two major subsystems as
seen in Figure 2.1
below.


Figure
1
.

The Architecture of
Organic.Edunet Portal


The federation of repositories subsystem includes the repositories containing either
the learning resources uploaded by the content providers
of the Organic.Edunet
project, or their metadata or both. As Organic.Edunet aims to spread high quality
learning resources related to OA & AE the above
-
mentioned federation of repositories
D
3.1 Organic.Balkanet web portal design

/
25

is only fed with resources certified by a quality process carried o
ut by experts from
European associations and universities.

The Organic.Edunet Web portal is the second subsystem, and provides general
services to portal users (such as learners, teachers, farmers, etc.), each type defining a
type of access to the learning

resources catalogued. The information about the
resources available is automatically fed into this subsystem from the federation of
repositories. Since the main scope of the Web portal is allowing the final users the
utilization of the semantic search cap
abilities of the underlying repository, it is
necessary to define the research technologies which sustain the foundations of such
repository.

The chapters to follow, present briefly some of the technologies used in
the implementation of the Organic.Edunet
Web Portal.


3.2

Organic.Edunet Portal

The Organic.Edunet Portal is hosted in
http://portal.organic
-
edunet.eu
.
In the
following pages, screenshots from the Portal are presented, showing the
functionalities and

relevant information presented on the website. Figures 2.2 and 2.3
present the Organic.Edunet Web Portal homepage. Searching functionalities are
offered throughout the portal, and access to resources on OA & AE is facilitated
through multiple areas in the

site. Additionally, on the left
-
hand side menu, more
information is presented regarding the Organic.Edunet project in general and more
specifically on the content collections and communities of practice that are involved
in the project, as well as the qua
lity procedure that is followed to ensure high quality
resources.

Homepage of the Organic.Edunet Web Portal


In the middle and bottom part of the homepage, selected resources on OA & AE are
presented. More specificall
y, as it can be seen in Figure 2.3, a featured resource is
presented in the big grey area. This resource is intentionally selected by the
Organic.Edunet consortium to reflect the quality of resources on the Portal and is
changed regularly. Following this r
esource, three tabs exist that show the most recent,
most popular and most viewed resources on the portal. In this way, the users can
easily navigate through resources that have been appraised and well accepted by other
users.

MOLE (Multimedia Open Learning Environment)

MOLE (Multimedia Open Learning Environment) is a multimedia information system
for managing courses, supporting learning processes and lear
ning communities
through the Web. The platform includes features for self
-
learning and reuse of
educational material in different platforms compatible with the international SCORM
standard.

MOLE was initially developed to support education and organize lab
oratory processes
and learning communities for the needs of the Electronic and Computer Engineering
Department of the Technical University of Crete and is constantly enriched with new
services and applic
a
tions for learning using multimedia.

dynamic presentation of statistics and performance indicators for the courses



interoperability with other educational systems with the SCORM export
feature

Specifically, MOLE offers a set of services for:



the orga
nization and management of digital educational content (Lectures,
notes, exe
r
cises, technical lab material, FAQs etc.)



informing learners (Announcements, Calendar, literature, personal rating etc)



learning communities (Mailing lists, live chat rooms, forum
s, personal
messaging, i
n
stant messaging, annotation tools)



s
upporting educational activities (Registration to courses, formation of lab
teams, e
x
ercise uploads and deadline management, assessment tests)



m
onitoring services (Course usage statistics, class
performance indicators)

The technical development of the system was
done
in such a way as to ensure the
following requirements:



Ability to install the system on any platform



Support for large volumes of information and scalability



Easy future development o
f new educational services



Development of functional graphical user interfaces highly responsive and
easy to use



Development of mechanisms for security of use and data protection

MOLE users have access to the course material and are informed on the progres
s of
the courses that interest them. They also have the ability to communicate with other
users, create working groups, and electronic upload of their work and many other
services.


MOLE users may belong to different categories. Each user group has access
to
different se
r
vices on the platform.

For example, in the case of the system customization for the needs of
a

polytechnic
depar
t
ment, the following categories of users
may be

created:



Undergraduate Students



Graduate Students



Faculty



Laboratory Staff



Secre
tariat



Guests



System Administrators

In MOLE access is allowed to designated users. Users can belong to different
categories a
c
cording to their class and have access to a range of services as described
below.

After login to the system, each user enters the
initial page that is a personalized view
of the site and provides direct access to the courses in that the user is interested and
quick updates on changes that have happened in the website and are of special interest
for the user (e.g. new courses announce
ments, work upload deadlines, new answers to
course discussions, etc.). Moreover, in the context of learning communities support,
the user is able to find out who from his/her
favourite

users or partners in various
subjects are connected at that moment, wi
th whom (s)he may come into direct contact
through the communications services of MOLE.

4.1

Web Courses in MOLE

From the initial design phase of the MOLE system, the main objective was to develop
a sy
s
tem th
at fits both the model of tele
-
education, and the hybrid model of education.
The term mixed or hybrid education means any mixture of traditional education and
tele
-
education. The traditional method of learning is being enhanced with technology
and tele
-
edu
cation methods to acquire new dimensions and possibilities, leading to
more flexible models of education. More specifically, the educational organization
organizes training courses in which a part of the learning takes place in traditional
classrooms and l
aboratories (which cannot be avoided especially in polytechnic
departments) and the other part by using modern methods and asy
n
chronous tele
-
education (e.g. digital educational materials, e
-
classes, mailing lists, virtual
di
s
cussions, communication and coo
peration between trainers and trainees, etc.). This
model of education is based on traditional education and is assisted by the services
that are provided through tele
-
education.

The hybrid learning organization provides a significant learning opportunity
as it
combines the immediacy of communication among the instructor and the learners and
D
3.1 Organic.Balkanet web portal design



14
/
25

the irreplaceable practical training in laboratories and the convenience, flexibility and
self
-
regulation of educ
a
tion without the time and space constraints. This hybr
id
organization aims to support educ
a
tion as an efficient set, which achieves the
optimum exploitation of the strengths of both a
p
proaches (traditional and tele
-
education).

MOLE was developed to cover as much as possible the learning needs following the
mo
del of asynchronous learning to provide support in courses, as well as the model of
synchronous learning with the use of multimedia.

MOLE system allows the instructor of an electronic course to manage an autonomous
area and organize the course the way he w
ants to. Each course is connected with an
abstract course from the curriculum which allows its categorization and its connection
with the cognitive area that belongs to.


Figure

.

Course main page

A course administrator in MOLE h
as the ability to enter or edit the description of the
course, to enter information about the teaching of the course (e.g. class rooms, time,
teaching assi
s
tants, etc.), and to upload material on the subject matter, bibliography
and useful links. All these

elements constitute a complete presentation and are directly
accessible from the main page of the course. From the main page of the course each
user has the ability to navigate in all instances of the same course that are available in
the system from prev
ious periods (e.g. semester).

To support training MOLE provides to the instructor a set of services. These services
aim to improve co
mmunication and cooperation,
to provide better information and
remote access to course materials, as well as automation of
necessary training
procedures and support and cre
a
tion of learning communities.

Multilingual Interfaces Support

For the needs of
other projects in the future
, as now Organic.Balkanet
, MOLE was
adapted in order to support multilingual interfaces. For this

reason an intuitive form
based interface was
provided by

MOLE in order to be able for the designated users to
provide translations for each MOLE element from a selected language (reference
language) to another (translation la
n
guage). When the translation
to a specific
language is completed, MOLE interfaces can be switched to the user preferred
language.

,

provides access to a federation of several learning repositories that
have multilingual, quality

is a multimedia info

develo
ped by TUC
for
managing courses, supporting learning pro

provide educational
material in the subject of Organic Agriculture

that will be previously created
by Agricultural professionals at MOLE platform
. This middleware allows for
the publishing of the MOLE learning resources metadata in other
OA

Harvesting (OAI
-
PHM,
http://www.openarchives.org/OAI/
openarchivesprotocol.html) to support metadata harvesting of MOLE learning
resources from Organic.Edunet Feder
a
tion services.


By t
his way the metadata of learning re
sources residing in MOLE
will be

available from Organic.Edunet making possible the search and access of MOLE
learning resources using the Organic.Edunet services.


5.1

Learning Resources Metadata

The initial design of MOLE system supported a minimum set of met
adata for its
learning r
e
sources (e.g. identifier, title, description). The metadata for describing
MOLE learning r
e
sources should be extended in order to support their harvesting to
other learning repositories. In this case we want to achieve communicatio
n with the
Organic.Edunet Federation. For this reason,
will be necessary to describe an
Organic.Balkanet
Application Profile
for the

exploitation of MOLE learning resources
metadata.


5.2

Organic Agriculture Repositories Federation

Organic.Edunet is an inform
ation
gateway which a
ims to facilitate access, usage and
exploitation of digital educational content related to organic agriculture and
agroecology topics.
T
he recorded learning resources are listed with page navigation in
content portfolios, and each reso
urce is identified with almost every metadata
elements from LOM standard both in En
g
lish and its original language. At top right
section of page, relevant link, content type, usage rights and screenshot of a resource
are displayed. The resources are access
ed via this link, externally. The repository
containing local learning resources mainly in text/pdf format in addition to external
resources is also equipped with harvesting tools for OA content on other repositories
and internet.

5.3

Communication Middleware


The External (Agricultural) Repositories Communication Middleware

provided by
MOLE

is responsible

for the communication
of MOLE
with external repositorie
s that
provide educational mate
rial in the subject of Organic Agriculture. This middleware
allows for
the publishing of the MOLE learning resources metadata in other OA

federations, and inversely the ex
ploitation of the content residing in external OA
federations/
repositories in MOLE courses.

To achieve this
two
-
way
MOLE

implements
Open Access Initiative
Protocol for
Metadata Harvesting (OAI
-
PHM, http://www.openarchives.org/OAI/
openarchivesprotocol.html) to support
MOLE learning r
e
sources m
etadata harvesting
from Organic.Edunet Federation services.

This way the metadata of learning
resources residing in M
OLE will be available from O
r
ganic.Edunet Federation
making possible the search and access of MOLE learning resources using the
D
3.1 Organic.Balkanet web portal design

Organic.Edunet services. The module that implements this functio
n
alit
y is the
Metadata Expose Module
.

5.3.1

OAI
-
PMH

The OAI
-
Protocol f
or Metadata Harvesting (OAI
-
PMH) [Lagoze et al., 2002; OAI
Forum Tutorial; Fegen, 2007] defines a mechanism for harvesting records containing
metadata from repositories. In the OAI context, harvesting refers specifically to the
gathering together of metada
ta from a number of distributed repositories into a
combined data store. The OAI
-
PMH gives a simple technical option for data providers
to make their metadata available to services, based on the open standards HTTP
(Hypertext Transport Protocol) and XML (E
xtensible Markup Language). Although
using Dublin Core in metadata records is mandatory in OAI
-
PMH, it supports the
exchange of any metadata agreed by a community that can be encoded using XML
and for which there is a valid XML Schema definition. Thus, met
adata from many
sources can be gathered together in one database, and services can be provided based
on this centrally harvested, or “aggregated” data. The link between this metadata and
the related content is not defined by the OAI protocol.


Figure

.

Basic functioning of OAI
-
PMH (retrieved from [OAI Forum Tutorial])

OAI
-
PMH is based on client
-
server architecture, in which 'harvesters' request
information on updated records from repositories [Fegen, 2007]. A harvester is a
clien
t application that issues OAI
-
PMH requests, and is operated as a means of
collecting ('harvesting') metadata from r
e
positories. A repository is a network
-
accessible server that can process the six OAI
-
PMH r
e
quests described below, and is
managed by a data
provider to expose metadata to harvesters. Data providers handle
the deposit and publishing of resources in a repository, making the a
s
sociated
metadata available for harvesting by service providers. A Data Provider maintains one
or more repositories (web
servers) that support the OAI
-
PMH as a means of exposing
metadata. A Service Provider on the other hand issues OAI
-
PMH requests to data
providers and uses the metadata as a basis for building value
-
added services. A
Service Provider in this manner is "harv
esting" the metadata exposed by Data
Providers.

To allow various repository configurations, the OAI
-
PMH distinguishes between
three di
s
tinct entities related to the metadata made accessible by the OAI
-
PMH:



a resource: what the metadata is about



an item:

a constituent of a repository from which metadata about a resource
can be disseminated, and



a record: metadata expressed in a single format.

D
3.1 Organic.Balkanet web portal design



20
/
25

OAI
-
PMH specifies that unique identifiers are provided for items.

OAI
-
PMH does not support search and retrieval

across this data, it simply makes it
possible to bring the data together in one place (harvesting). In order to provide
services like search and retrieval, the harvesting approach in OAI
-
PMH must be
combined with other mechanisms. Although the OAI
-
PMH is
technically very simple,
building coherent services that meet user requirements remains complex.

OAI
-
PMH supports six types of requests (known as 'verbs'), which must be submitted
using the HTTP GET or POST methods:

Semantic
Learning Resources at Organic.Balkanet

The Ont
-
Space semantic framework is responsible for provid
ing the Organic.Edunet
and Organic.Balkanet services
with the infrastructure for the meaningful management
of learning resources metadata in a semantic format, using the Ontology Web
Language (OWL).


Built upon the Jena Semantic Web framework, the Ont
-
Spac
e repository makes use of
these experimental technologies, often used only in research environments, and
transfers them into a production environment aimed for end user interaction. Using
the OWL language, any specific knowledge domain (and particularly th
e OA&AE
knowledge domain, for the purposes of the Organic.
Balkanet

project) can eventually
be represented as an ontology, and so it can be stored in such a semantic repository,
and used in order to perform the semantic capabilities associated to it.


Ontol
ogy
-
based systems allow performing automatic reasoning, which can be
achieved by the use of reasoners to infer new information from the data in the
ontological model through the application of logical rules. In particular, Ont
-
Space
uses the lom2owl ontolo
gy, a mapping of IEEE LOM to the OWL ontology language,
to store learning resources’ metadata in a semantic form, thus facilitating the
application of reasoning capabilities based on the information stored in learning
objects metadata.


In the above
-
mentio
ned lom2owl ontology, learning objects are represented as
instances of the concept learningObject. Regarding its metadata, certain categories
from the IEEE LOM standard are first level concepts in the ontology, such as IEEE
LOM categories 7.Relation (lomRe
lation concept), 8.Annotation (lomAnnotation
concept) or 9.Classification (lomClassification concept); whilst other IEEE LOM
elements are represented through several ontology concepts or attributes, such as
category 3.Meta
-
Metadata, represented as several
attributes in the learningObject
concept, while its sub
-
section 3.2.Contribute is represented as a first level concept
(contribution concept).

Organic.Balkanet

Search by competencies

Learning outcomes used in Organic.Balkanet courses are based on the def
inition used
in the European Qualifications Framework (EQF).

The EQF defines levels of
qualification in terms of knowledge, skills and competence or accountability.
Learning outcomes reflect overall competence in terms of what a learner knows,
understandi
ng and is able to do on completion of the learning process and are defined
in terms of knowledge, skills, responsibility and accountability.



One previous task in Organic.Balkanet is to

prepare
training course
s

for acquiring the
professional competences f
or Organic.Balkanet based on the fact that

there is a
necessity of new knowledge


about the requirements, which the agricultural

.

The application of the EU standards of training will contribute for achievement and
recognition of professional competences, and transparence of qualifications end users
of Organic.Balkanet project.

in terms of required competencies.


Competence
means the proven ability to use knowledge, skills and personal, social
and / or methodological abilities in work and study situations
and in professional
and/or personal development.


Currently Organic.Edunet provides different search mechanishms.
But
Organic.Balkanet will provide a new search mechanism through Organic.Edunet Web
Portal, search by competencies.
