1. A processor-implemented system of storing annotations with associated type information in a structured data store, comprising: a text analysis engine for generating annotations and associated object graphs showing relationships between objects and for storing the annotations and associated object graphs in a database, wherein each of the annotations is related to another of the annotations based on an action and an initiator of the action with respect to an input object; a schema generator for mapping an input object type system into a queryable structured data format, wherein the structured data format and associated data including the associated type information persist in a structured data repository, wherein the structured data format includes an XML schema having a name of the input object type for the input object type that is a base type, and the XML schema is a subtype of another schema for the input object type that is not a base type; a structured document constructor for mapping input data from input objects in the input object type system to the structured data format; and a search interface for applying an input query to the structured data repository.
