Information MAnagement and interoperability of content for distributed Systems of high volume data repositories through multi agents Systems Architecture First prototype (focus on local sources)First prototype (focus on local sources) –Local agents map from database schema to conceptual schema –Uses RQL: a declarative language to query both RDF descriptions and schemas Second prototype (focus on interoperability of containers)Second prototype (focus on interoperability of containers) –Local agents communicate with agents using global schemas (such as CIDOC-CRM) translating between them –Introduces a first version of the graphical user interface Third prototype (focus on semantic interoperability)Third prototype (focus on semantic interoperability) –Utilizes the virtual reference room including reference works like dictionaries and thesauri –Using these, agents cooperate in achieving semantic operability
