The International Defence Enterprise Architecture Specification for exchange Group (IDEAS Group) is a project involving four nations (plus NATO as observers) and covering MODAF (UK), DoDAF (US), DNDAF[1] (Canada) and the Australian Defence Architecture Framework (AUSDAF).
The W3C Resource Description Framework (RDF) and Web Ontology Language (OWL) will be the format used for data exchange.
A demonstration of multinational interoperability is scheduled for September 2007, based on exchanging process models for casualty tracking.
The ability to exchange architectures between countries enables better understanding of each other's capabilities, communications mechanisms and standard procedures.
In practical terms, this means the ontology is well suited to managing change over time and identifying elements with a degree of precision that is not possible using names alone.
