The Agrof-MM Erasmus+ project reinforces the AgroFE project that ended in 2015. The objective of the Agrof-MM project is to train European agricultural stakeholders in agroforestry practices. The project will give them the opportunity to familiarize themselves with agroforestry, and to improve their knowledge of it, in order to work towards the development of agroforestry in the Mediterranean and mountain regions of Europe. Thus it widens the geographical scope and improves the level of training of the AgroFMM project, as well as addressing new stakeholders from 15 partners. The paper describes the knowledge databank system prototype for Agroforestry training and education. The knowledge databank is a component of the project training system. It aims to gather and share a set of documents, resources that partners can use and which will have been accessed by learners and the public users. These resources are under different forms: Mono document objects and Composite materials.
In last decades regional growth of arable land has a significant effect in global and European land use, thereby reducing the percentage of natural forest area. In Europe are 29% croplands, and in Central and Eastern Europe in Hungary arable land ratio is near to 50%, which is much higher than the European average. The global environmental problems justify the necessary of forestation in each country. However, this causes conflicts of interest between the agricultural and environmental sectors. Solution of the conflict management may increase the agroforestry land use, which means ecologically mixed land use. The European Stakeholders has accepted that agroforestry has special ecological system.
The aim of the AgroF-MM (Agroforestry Education, Mediterranean and Mountains areas) project is to play an important role in Agroforestry trainings. Depending on the European countries, states or professional organizations and training actors try to reintroduce Agroforestry in the course of training and qualification in initial training and in adult education.
The aim of the Agrof-MM project is to involve farmers, future farmers, advisors
and stakeholders in Agroforestry. This agricultural system has experienced a strong
abandonment in the 20th century, to count today only a few million ha in Europe
Depending on the countries, states or professional organizations and training
actors reintroduce Agroforestry in the course of training and qualification
The core of the EQF (European Qualification Framework) concerns eight reference levels describing what a learner knows, understands and is able to do (learning outcomes). Levels of national qualifications will be placed at one of the central reference levels, ranging from basic (Level 1-L1) to advanced (Level 8-L8). This will enable a much easier comparison between national qualifications.
But in order to achieve, to support these conversions, these profound changes in
modes of practical production, we need counsellors-advisors, trainers, specialists and
unfortunately the level of human resources is low. The partners have identified
training needs in the short term
L3-L4-L5 level, sometimes L5 level, • the advisors-teachers-specialists, mainly level L5+L6,
In the short term, the project will address these 4 needs / three publics through an
AgroF-MM training system established by the partners, partly based on the AgroFE
Leonardo project, the development of the EU AgForward RTD (AGroFORestry that
Will Advance Rural Development, Research and Technological Development) 7th
research, the EURAF (European Agroforestry Federation) EU research association
and its working groups, and the outcomes from the French RMT and Casdar
(Fertilisation and Environnement- Frnch acronym) programme. The project would
be built on innovative teaching and training practices
Supporting the agroforestry development (training on different levels
The knowledge management (KM) is used to describe the creation of knowledge
repositories, improvement of knowledge access and sharing as well as
communication through collaboration, enhancing the knowledge environment and
managing knowledge as an asset for project partners and public. The central element
of the KM is the KDB. For building and using the KDB knowledge engineering is
needed. Organizing and storing the knowledge (represented in different content and
forms: documents, videos, photos, etc.) it is need to classify them by using
knowledge representation technologies. In the project the Dublin-Core
The very important part of the development to define the AgroF-thesauri in very
detail because the word in this vocabulary links to different object (document,
lecture, presentation, videos, etc.) in the KDB. This thesauri system has been
developed by a working group in the project using ontology. Unfortunately the
AGROVOC Multilingual agricultural thesaurus and other system don’t contain terms
for agroforestry in details
The main objectives are to make a synthesis of needs and expectations. The work
based on the present existing training actions and to set up a common framework.
Within this framework the target is to build an innovative training system
(contextualized, modularized trainings, use of ICT (Information and Communication
Technologies), professionals participation), to create a technical collaborative
support for the implementation of the project with communication tools (information
of partners and promotion) and providing access to the resources and training
services during and after the project (knowledge databank, interactive services). To
achieve these objectives the following main activities had to be carried out
A knowledge base or knowledge bank is a special kind of database for knowledge
management. A knowledge base is an information repository
The developed system architecture can be seen on the Fig. 1.
In the context of the AgroF-MM project, the used Information and Communication Technologies (ICTs) include four components: the collaborative tools, the Knowledge DataBank, the tools for training and archiving and a portal that integrates the tools.
The KDB, is to enable the sharing, access and consultation in the use of certain resources for training. These resources are under different forms: • Mono document object, like a photo, a text, a diagram. • Composite materials, for example an html web page with images, “pdf” files with pictures and diagrams, a video clip, with images and sounds, etc.
Under the project, these documents are identified, selected, proposed by partners and included into the KDB for the evaluation of their potential use in training, by one or more partners. A fact sheet originally written by the proposer, the institution, who proposed it to project partners, often accompanies, completes this document.
At the end of the evaluation phase, the KDB can be extended to other contributors, for other uses, such as exchange supports between different actors of Agroforestry.
There are more objectives of the KDB, which are the followings:
Storing elements of knowledge, sources of technical and professional information in relation with the domain, elements, components that could be usefully used in education and training; Making professional experiences accessible to learners, students, adults in training, experiences under the form of documents, videos, evidences, keynotes; Allowing the diffusion of knowledge under the form of apprenticeship modules, together or linked to education and training platform; Being one of the support tools for the curricula and trainings established, developed by the project, proposed to students, to adults, target; Allowing to professors, trainers, instructors to develop innovative curricula, educations pathways, new types of pedagogical activities; Being, in the project, one of the support tools of the collaborative and interactive working, especially as a mean to help the production of new education and training and professional targeted knowledge; Bringing and bridging the other related KDBs (Agronomy, Agro ecology, Environment, Water, Organic) and Agroforestry sources wherever they are located on Earth; In mid-term, enlarging the domains of agroforestry which are covered by the KDB, for instance knowledge from Mediterranean, African, Asian, experiences, professional practices; In mid-term, making this knowledge accessible to other people as learners, to other learning organizations, institutions like universities, training centres, in respect with intellectual property; In long-term, for the “public part” of the KDB, making this knowledge accessible to large public, in respect with intellectual property. 3.3
We need a place to store and structure the information and sources gathered by the project. This place can be divided into 2 parts: • Private part • Public part, which means not restricted to partners but, for instance, open to trainers and learners. • The project needs to build the curricula and trainings, especially the technical / professional components, which stored in a repository for the information: • A repository to store the “objects”, the documents, the resources, the components of the modules the project is producing and will produce; • A place to, possibly, store some “objects”, documents, which are involved in working tasks, in conjunction with the collaborative working system; • A set of tools to identify the KDB components (indexation) and tools to make this information easily accessible, search engines for instance; • We can review some aspects of technical needs: • Amount of data to be stored, we have to define technical constraints; • Number of users, number of access, in short term and in midterm; • Related parameters like quantity of information by user, duration of connection, bandwidth.
The issue of private data (linked to restricted access for instance) must be specifically treated in the second step of the project in conjunction with the access by learners, students in relation with LMS (Learning Management System).
In computing, a database is gathering highly structured data, a well-defined organization, based on different types of structures: relational, hierarchical. This is absolutely not the case in a databank in which we store structured tables of numbers as well as illustrated text or video or emails, external knowledge or those from the project in their various forms. But it should be noted that the knowledge databank in the prototype of the AgroF-MM project is based on a software, RUBEDO developed in PHP and it is built on different components: • a database management software (DBMS), type 'NoSQL', MongoDB; • the user interface uses the ElasticSearch search engine.
Why we chose MongoDB as a database server. From one side the Rubedo system is an open source software tool framework to develop websites and it contains this type of database. From the other side MongoDB is an open-source document database and leading NoSQL database. The benefits of using a document database like MongoDB means that we can work with JSON-style documents across our entire development process.
In this type of database is possible search based on text or in case of pictures videos and other objects based on taxonomy (description text to the given object).
The Rubedo platform brings the advanced functions of content management together
with the power of e-commerce, all being based on Big Data
The Rubedo system can be accessed on three different platforms (Linux-RedHat or Debian and Windows):
We use a yum based distribution, which name is: CentOS. The first step is installing the MongoDB, then the Elasticsearch and Apache webserver and PHP server side script language and finally the Rubedo system.
If the installation was correct you can add different kind of users with different rights to the system.
If the given username and password were correct can be seen the Backoffice part, where the appropriate pages for the users can be designed. These pages can be seen by users on the FrontOffice part in different kind of browser programs (Fig. 2).
There can be seen more possibilities to choose. The visitors, learners, trainers, the access is by means of the address newkdb.agrofmm.eu without further specification. This version is open to the public. The opening welcome page is displayed in English, with a brief introduction, (picture below – Fig. 2.). The choice of language of the interface is done by clicking on the language button, pull-down menu, select language and redisplay the page in the selected language. The general menu Welcome, Overview, Trainings, Resources, Content types, Search tool and Wiki and a knowledgebase DVD from the former AgroFe project results is present on every page. The logo AgroF-MM repeats on every page with a click (on the logo) from any page. Site map levels and a breadcrumb used to be located and to move without necessarily go back to the Home page.
The KDB has documents and links with training. Users access Digital Assets Manager contents. a) The choice “Trainings”' provides access to “Trainings needs” and “Trainings objectives” of the KDB. b) The choice Resource opens a submenu in a dedicated page. The route tree in the resources of the KDB continues with the choice: - Gallery: the selection of choice provides access pictures, where number of thumbnails are in the bank. By clicking on a thumbnail, the image in full size is obtained. Video: click on the video option causes the access to video stored in the DAM (Digital Asset Manager) or the recorded videos and identified on public servers, such as YouTube, etc. Some videos can be viewed online, others have to be downloaded. Document: offers a sub-menu distinguishing between general information and agroforestry techniques. A click on the document product logo to download the document and its display in the user's browser if a necessary application was installed. c) The content types menu is a description about the usable types of content in the
Rubedo system. d) Selection Search provides access to the integrated search engine has the knowledge bank. In this application, the search can be performed on the entire contents of the bank by entering a keyword may be presented in an object or an associated content. Here can be used the object associated taxonomy for better performance searching. e) AgroF-MM wiki is work in progress, in line with the taxonomy “agroforestry” of the bank. f) A knowledgebase DVD from the former AgroFe project results in html format.
One of the most important part of the development to define the AgroF-MMthesaurus (Fig. 2) in very detail because the word in this vocabulary links to different object (document, photos, presentations, videos, etc.) in the KDB. This thesaurus system has been developed by a working group in the project using ontology. Unfortunately the AGROVOC Multilingual agricultural thesaurus and other system do not contain terms for agroforestry in details.
For designers and developers, the design and developments associated with the management and use of the KDB covers more extensions. The ”professional domain” extension composed of Vocabulary, Thesaurus, Taxonomy of agroforestry. The ”training” extension is dealt the question of the enrichment of documents. In relation with KDB access, different modes and levels of enrichment have been developed and implemented.
The first step to identify the internal objects of KDB. In the second step we can enter keywords (metadata) to the objects (photos, graphics, videos) to help searching process. We use 4 taxonomies (Domain, Dublin Core, Learning Object Metadata, Technical definition of metadata). Finally we can associate these keywords to the appropriate objects in the KDB (Fig. 3).
The aim of the AgroFE project is to play an important role in Agro-forestry trainings. Depending on the European countries, states or professional organizations and training actors try to reintroduce Agro forestry in the course of training and qualification in initial training and in adult education.
The Rubedo platform brings the advanced functions of content management, all being based on Big Data. We use a yum based distribution, which name is: CentOS 7. The first step to install the MongoDB, then the Elasticsearch and Apache webserver and PHP server side script language and finally the Rubedo system. The visitors, learners, trainers, the access is by means of the address newkdb.agrofmm.eu without further specification. This version is open to the public. The choice of language of the interface is done by clicking on the language button, pull-down menu, select language and redisplay the page in the selected language.
During the development work of the KDB, an evaluation of the interface and the organization of the access will be organized with the participation of master students, Hungarian and French consultation conducted by students in Master AgroSup Dijon. A first phase resulted in proposals for interface and aspects. The thesaurus and taxonomy are very important part of KDB, it can be the base on the search strategy.
The KDB has documents links with training. Users access Digital Assets Manager contents.
The knowledge database (knowledge data bank) is very new innovative solution for harvesting, storing and delivering contents in agroforestry. It was used in different training programs with good feedback. The knowledge database will serve the Agrof-MM partners in the next years.
