Booz-Allen is helping to design and develop a Crisis Management System to provide collaborative analytical and presentation capabilities. To facilitate the distributed use of content information, content metadata is represented as C++ objects and operated upon using CORBA interfaces. Requiring that such applications implement CORBA interfaces to access metadata objects proved to be a barrier to integrating other applications with the system. Using the XML-based Resource Description Framework (RDF), a representation of the metadata was developed. This representation eases integration difficulties and facilitates more flexible usage of metadata by components and applications.This paper presents the development of a browser-based application used to evaluate the usability of distributed metadata objects represented in RDF. It describes the rationale behind using RDF as the metadata representation. The development of the application has proven the viability of using RDF to represent metadata.
