“…Equivalence Access Links among objects (EALo): these links are based on hypothetical semantic equivalences among resources (mostly synonymic connection [2]) found by the data-oriented cooperative system. An EALo between two resources A and B may allow a user to have rights over B if he has rights over A. x An inclusion link: R2 authorizations are included in R1's ones.…”

“…In this context of open and cooperative information systems, research has been focused on the interoperability among data sources, related to schematic and syntactic representations, and semantic expression [1] [2]. Cooperate infers to respect independency and autonomy of local systems by providing communication and coordination processes to share data and services.…”

In the context of cooperative information systems, research focused on the interoperability among data sources, related to schematic and syntactic representations or semantic expression. Security introduces new problems of heterogeneity. In this paper we refer to the different ways to represent authorization and rules in access control policies. Our proposition consists in using a role based multy-policy model to represent heterogeneous policy in the same formalism. We also map the local policies creating access bridges and we propose a set of security controls to filter a global user query.

To solve the semantic conflicts in the cooperation of heterogenous databases, we propose a multi-agent system which contains domain ontologies. When a local source is added by an expert, ontology is dynamically created by the system. The expert can also completed it. It evolves with the update of the local base but also when an user performs a query. A process examines the query and creates temporary semantic links. These must be validated or not by the user. The result validation implies the version creation from temporary links. The modification and deletion of database elements by the expert perform the ontology evolution. Our research work treats evolution by the version concept.

“…The interoperability problem is well known and recurring in many domains, some examples are: database schema integration [9], interoperability between modelling techniques [10], interoperability in meta-modelling platforms [11], interoperability of ERP with other systems [12], interoperability between heterogeneous information systems [13,14] and in manufacturing [15]. Furthermore, it is possible to identify large problem domains such as the healthcare domain which suffers from difficult interoperability problems as described by Dogac et al [16].…”
