Abstract
A method for management of federated information in associated knowledge systems. The method includes maintaining a data structure, the data structure including associative metadata that correlates a plurality of substantive knowledge entities from a plurality of disparate knowledge bases; monitoring the substantive knowledge entities for an access-limiting event; determining the access-limiting event on at least one of the substantive knowledge entities; and responsive to determining the access-limiting event, adding to the associative metadata a persistent audit enhancement indicative of the access-limiting event, the persistent audit enhancement including a timestamp. The access-limiting event may include deletion of a substantive knowledge entity, enacting more restrictive access permissions for a substantive knowledge entity, and copying of a substantive knowledge entity to a more restrictive access area.
