Learning Content Management Systems (LCMS) supports e-learning applications with storage and efficient access for e-learning objects (LO)s. ROSA is a LCMS built as a semantic layer on the top of an XML native DBMS, Tamino. Together, ROSA and Tamino, offer instructional designers a semantic view of e-learning content. In this paper, we present ROSA Data(More)
OBJECT Deep brain stimulation (DBS) is used for treating various types of dystonia. Multiple electrodes could be proposed to improve the therapeutic outcome enabling the targeting of specific neuronal populations not reached by the electrical field generated by the initially implanted electrode. The authors address the question of the feasibility and safety(More)
Learning content management systems (LCMS) supports e-learning applications with storage and efficient access for e-learning objects (LO)s. ROSA is a LCMS built as a semantic layer on the top of an XML native DBMS. In this paper, we present ROSA data model designed as an extension to RDF data model with ordered collections and relationship properties and(More)
Metadata, or “information that makes data useful,” have been considered by the database community basically as data in dictionaries used to control database management systems operations. More recently, metadata have been used to describe digital resources available across networks. This paper presents a survey of the state of the art concerning the use and(More)
Data warehousing is a collection of concepts and tools which aim at providing and maintaining a set of integrated data (the data warehouse) for business decision support within an organization. They extract data from different operational data sources, and after some cleansing and transformation procedures data are integrated and loaded into a central(More)
Learning Content Management System (LCMS) supports e-learning applications with storage and efficient access for e-Learning Objects (LOs). In order to foster LCMS adoption by the e-learning community, an important issue is to bring course modelling to the realm of the LCMS. In this paper, we describe the Repository of Objects with Semantic Access (ROSA)(More)
ROSA is an e-learning system which enables the management of Learning Objects (LOs). However, since ROSA is a centralized system, it does not provide the integration of LOs created in other institutions. This paper presents the P2P distributed system developed for ROSA, named ROSA - P2P, which provides the physical environment to carry out the integration(More)
