Program complex VEDA is intended for creating  the fields of  formalized knowledge in the form of structured documents storages focused on applications of knowledge processing technology and  automatic control of  the documents life cycles [1]. This article deals with elements of the approach on expansion of the  possibilities of documents spaces for knowledge domains to represent general knowledge properties by means of inclusion in its structures special components that contain  description of classification schemes and structures for collections of documents and their parts. Applications are considered for problems which decision is supported by hierarchies of the information structures created above systems of connected documents.
The information model of documantary space [2] includes metamodel for structures of connected documents and processes together with concrete objects and does not depend on a subject domain features. The system of the connected documents and their parts is concidered as the base semantic network of documentary space forming foundation of hierarchy of semantic metanets. 
Elements of such a hierarchy  are represented by networks for specifying structural and functional descriptions of fragmentation and generalization of networks of  semantic hierarchy previous levels. These descriptions realize the multiple-valued classification for various points of view on an origin, maintenance and ways of application of the data contained in formalized documents. Such multiplicity of the points of view naturally arises when the system of semantic relations for documents and their parts derivates new quality of opportunities for processing the information. 
Metanets descriptions allow to allocate and index the information resources appropriate to such descriptions, to organize access, search and navigation on documentary space. Unification procedure for internal semantic networks descriptions with fragments of semantic networks on the subsequent levels of hierarchy is applied for these purposes. It includes operations of comparison in relations “to be” and “ be a part” and estimations of a degree of concurrence.
The allocated fragment of a base semantic network derivates the cluster of documents if the set of external connections with its elements may be replaced by system of connections series beginning with the reference on cluster., that  allows organize protection and management for access to information resources. The following types of  the classifications are  represented  by metanets for:  
•	an enclosure of documents structure and the contents;
•	similarity of fragments of a base network to regular structures of the connected documents and their parts represented by parallel-serial networks;
•	descriptions of users information needs;
•	life time cycles of processes, documents and classes of documents.  
Recognition of structure  and the analysis of the documents content is performed by rules based knowledge model with stages of initial structure  recognition, semantic classifications of separate parts and  establishments of communications between them.
