9. A document management system comprising: a document management apparatus included in a server computer configured to designate a desired document in a series of documents managed under a Document Management Alliance document object model and to make a connection to a desired node in a hierarchical tree-structure of the desired document; and a client apparatus configured to access the document management apparatus to make a document call request for the desired document by presenting a document ID including two character strings in the form of one of a URL syntax or a sentence construction, the first character string being a route node designating the document object and the second character string specifying at least one of a version, a rendition, or a content of the desired document, the document management apparatus including; a document call request accepting device configured to accept the document call request for the desired document, that is made by the client apparatus; an object ID analyzing device configured to separate said document ID into character strings for identifying at least one of said version, said rendition or said content of the document object; a document object operating device configured to execute operations in accordance with said character strings separated by said object ID analyzing device, said document object operating device further configured to provide a default value for at least one of said version, said rendition or said content of the document object; a connecting device configured to make connections to nodes in the hierarchical tree-structure of the desired document, that are designated by the document ID, sequentially from an upper level one to a lower level one; and a returning device configured to return, when a connection to the desired node specified by the document ID has been made, the prescribed information related to the desired node.
