A data management system, the system including: (i) an input interface for acquiring a source document; and (ii) a processor configured to: (a) divide the source document into multiple objects in response to content of the source document; (b) analyze the multiple objects to generate multiple low level sub-trees, wherein each of the low level sub-trees includes at least one of the multiple objects; (c) generate multiple mid level sub-trees, wherein each of the mid level sub-trees includes link to at least one of the low level sub-trees; (d) generate a top level sub-tree that includes multiple section links, wherein each of the section links to one of the mid level sub-trees; (e) create metadata descriptive of at least one of the sub-trees generated, wherein the metadata includes data which is not included in the source document; and (f) generate a structured document that includes the top level sub-tree, at least some of the mid level sub-trees and at least some of the low level sub-trees, and the metadata.
