An information deposit and retrieval system based on a resource-property data modeling. An exemplary usage of this system is to describe the properties of documents, pictures, web pages, etc. including their locations in the information deposit and retrieval system. Each document is modeled as a resource. Each resource can be associated with unlimited number of properties. A user can create a resource in the information deposit and retrieval system when he creates a document or comes across a web page by describing the properties of the resource. Later, when the user wants to locate the document, the user issues a query with specifying properties and values to the system. A typical query is to get the "location" property and other property of a resource by giving the values of name, author, and keyword properties. After the matching process, the system returns the matching resources and their location properties.
