The diversity of spatial information systems promotes the need to integrate heterogeneous spatial or geographic information systems (GIS) in a cooperative environment. This paper describes the research project ISIS (Interoperable Spatial Information System) which is a semantic mediation approach to support GIS interoperability. Its key characteristic is a(More)
BACKGROUND Cleaner-fish (wrasse, Labridae) are increasingly deployed within the Atlantic salmon (Salmo salar L.) industry as a biological control against sea-lice (Lepeophtheirus salmonis Krøyer). Two tank-based trials were performed to test the effect of farmed ballan wrasse (Labrus bergylta Ascanius) body mass and supplementary feeding on the delousing of(More)
In this paper, we highlight how wikis can be relevant solutions for building applications in domains characterized by a rapid evolution of knowledge. We will point out the capabilities of semantic extension to provide better quality of content, to improve searching, to support complex queries and finally to carry out on different type of users. We detail(More)
Scientific Information Systems (SIS) must move beyond data repositories and closed systems, to allow collaborations among different research disciplines, to include new types of data, to control data quality, and to enable semantic interoperability. Archaeological data include textual information, measures, sketches, photographies, 3D models, and a vast(More)
In this paper we show how the joint use of metamodeling and ontologies allows to describe domain knowledge for a complex domain. Ontologies are used as stabilized descriptions of a business domain while metamodels allow a fine description of the domain (to be constructed in the initial phases of modeling). We propose to use an ontology for early(More)
Biomedical domain and proteomics in particular are faced with an increasing volume of data. The heterogeneity of data sources implies heterogeneity in the representation and in the content of data. Data may also be incorrect, implicate errors and can compromise the analysis of experiments results. Our approach aims to ensure the initial quality of data(More)
Based on a survey of modelers’ practice, we propose a UML-based metamodeling architecture in which the two uppermost layers (meta-metamodeling and metamodeling) are organized into a mirroring structure. Using this architecture we can formally define a semantical integration of metamodels. We propose two applications of such metamodel integration: a(More)
Models have been playing a major role in information system engineering and interoperability: in this paper, we put an emphasis on the complementary role of metamodels. Metamodels are used as a core of two innovative platforms for information system interoperability. The first platform allows to combine formal and informal approaches for both modeling and(More)
