| Abstract | Le présent travail consiste en la conception et l’élaboration d’une banque de données des matières premières locales en Tunisie “BDMPL”. Ces données proviennent surtout d’études géologiques et de cartographie, de données de carrières et de travaux de recherche sur les matériaux utiles. Le volume de ces données est énorme mais elles sont actuellement hétérogènes et dispersées entre différents organismes: institutions universitaires, laboratoires de recherche, ministères, ... La création de cette banque de données permettra la collecte, la valorisation, la normalisation et la mise à disposition des informations auprès des intéressés pour consultations et analyses. La BDMPL présente les fonctionnalités principales suivantes: (a) Stocker de façon homogène et sécurisée l’information factuelle et géographique dans un système de base de données regroupant les différents domaines concernés; (b) exploiter et valoriser ces données grâce à des outils spécifiques; (c) mettre ces données à disposition du public de façon organisée, conviviale et sécurisée. Les domaines de données pris en compte dans notre étude sont les suivants: cadre géographique, cadre géologique, infrastructures à proximité des sites (voiries, ressources énergétiques, industries, ...), importance économique, propriétés géochimiques, minéralogiques et physico-mécaniques et références bibliographiques. Pour chaque domaine on disposera d’écrans de saisie nécessaires à sa gestion. Parmi les fonctionnalités de la BDMPL, l’utilisateur peut sélectionner, afficher et imprimer les données sur des sites ayant des critères en commun: même région géographique, même formation géologique, etc... De même, il peut faire des analyses de type statistique sur les propriétés des matériaux telles que le tri par plage de valeurs de propriétés ou la comparaison des caractéristiques des matériaux avec les spécifications et normes tunisiennes pour certains domaines d’utilisation. Ceci concerne essentiellement l’utilisation des matériaux argileux, carbonatés et sableux.As large quantities of materials are needed in the building and construction industry, the location of such resources is always important. To satisfy the increasing needs for these materials, it is necessary to constantly find new deposits which can be exploited. The search for such deposits can be guided by an analysis of existing data. The paper discusses the development of a bank of such data regarding local raw materials in Tunisia. Vast volumes of data are available from geological maps, quarries, academic institutions, research laboratories, ministries, etc, but it is heterogeneous in character and scattered. In order to provide quick access to the information, the data bank was created to collate the factual information from the various sources and store it in an organised and secure manner for access by the public. The domains of the data are the geographical information, geological characteristics, details of infrastructure, economic importance, geochemical tests, mineralogical studies, physical and mechanical properties, malleability of clayey materials and a bibliography. In general the information is displayed in tables relating the various topics/information. A search facility is available such that data on a number of topics can be accessed and the results provided pertinent to the specific topic. For example, the analysis of grain size would automatically be provided for sands, the Atterberg limits for clay and the mechanical properties of rocks, without the necessity to specifically request the results of individual tests. The search can be for a geographical region a geological formation, or materials, which meet specific construction standards. In this first phase, the collection/collating work has been undertaken under the auspices of the National Office of Mines. It is hoped that in the future it can be incorporated into a GIS system and that it will be possible to arrange for the ongoing storage of new information as it becomes available. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
