26. A computer readable medium storing computer program instructions which when executed by a computer performs a document managing operation of designating a desired document in a series of documents managed under a Document Management Alliance document object model and making a connection to a desired node in a hierarchical tree-structure of the desired document, the document managing operation comprising the steps of: accepting a document call request for the desired document, that is made by a client apparatus 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 document object; separating said document ID into character strings for identifying at least one of said version, said rendition or said content of the document object; executing operations in accordance with said character strings separated by said separating step; providing a default value for at least one of said version, said rendition or said content of the document object; making 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 returning, when a connection to the desired node specified by the document ID has been made in the connections making step, the prescribed information related to the desired node.
