Abstract
Modern Defense strategy and execution is increasingly net-centric, making more information available more quickly. In this environment, the intelligence agent or warfighter must distinguish decision-quality information from potentially inaccurate, or even conflicting, pieces of information from multiple sources - often in time-critical situations. The Pedigree Management and Assessment Framework (PMAF) enables the publisher of information to record standard provenance metadata about the source, manner of collection, and the chain of modification of information as it passed through processing and/or assessment. In addition, the publisher can define and include other metadata relevant to quality assessment, such as domain-specific metadata about sensor accuracy or the organizational structure of agencies. PMAF stores this potentially enormous amount of metadata compactly and presents it to the user in an intuitive graphical format, together with PMAF-generated assessments that enable the user to quickly estimate information quality. PMAF has been created for a net-centric information management system; it can access pedigree information across communities of interest (COIs) and across network boundaries and will also be implemented in a Web Services environment.
