International Classification:

G06F 1721

US Classification:

707514, 707 10, 7071041

Abstract:

A molecular document comprised of atomic documents located in a document management system is provided. The molecular document is generated within the environment of a document management system which separates the content of a document from the properties which are used to describe the document. The document management system further includes bit providers which retrieve the content portion of the document and deliver it to the document. The bit provider of the present invention is a specialized bit provider having the capability of retrieving full-fledged DMS-type documents. Particularly, the atomic documents of the present invention are stand-alone fully functional DMS-type documents which become the content of the molecular document. A user of the DMS is unaware of the fact that a document retrieved is, in fact, a molecular document.

International Classification:

G06F 1500

US Classification:

715515, 715513, 717 5

Abstract:

A document management system is provided which organizes, stores and retrieves documents according to properties attached to the documents. A property attachment mechanism allows an application to attach arbitrary static and active properties to a document. The active properties include executable code which perform document management functions to control the state and behavior of the document in response to a triggering event. In this manner, the state and behavior of the document is provided to a user and is accurately maintained even when the application is not running.

International Classification:

G06F 1730
G06F 1700

US Classification:

707200

Abstract:

In a computer system having a number of applications and storage repositories using protocols which are different from each other, a document management system is interposed into a content and/or property read/write path of the computer system. The document management system provides for attachment of properties to documents, which allow for separating the content of the document from the properties which describe the document. This separation of the document content from its properties allows for a user level access and control of documents providing for flexibility in organizing, storing and retrieving documents. Further, interface mechanisms are provided which allow the different applications and storage repositories to interact with the document management system. The interface mechanisms include translators and bit providers. The bit providers are configured with the translators and mechanisms to retrieve document content from the different storage repositories and to deliver the document content to a requesting document.

International Classification:

G06F 1300

US Classification:

395617

Abstract:

The present invention provides client-selected consistency guarantees to clients of a weakly consistent replicated database on a per "session" basis. The clients have access to utilities which allow the clients to, individually or collectively, define a "session" over which the selected guarantees are enforced. A "session" is broadly defined as a sequence of logically related Reads and Writes to the database. Sessions are initiated and terminated substantially independently of other sessions which may exist concurrently. Clients are allowed, however, to clone sessions and/or merge sessions with other clients. Clients select a minimum relevant subset of guarantees from among a set of pre-defined consistency guarantees, where "relevancy" is a client determined factor. At any given time, the system may be enforcing a number of different combinations of consistency guarantees. The guarantees ensure that all clients participating in a particular session view the database as having certain conditions of data consistency--the consistency of which is only provided with respect to the participants' Read and Write requests.

US Classification:

707500

Abstract:

A document management system is provided which organizes, stores and retrieves documents according to properties attached to the documents. A property attachment mechanism allows a user to attach arbitrary static and active properties to a document. The active properties include executable code which dynamically change system configuration of the document in response to a triggering event which is predefined by the user. The present invention eliminates the generally tedious and error-prone process of configuring and reconfiguring an existing system configuration in response to new or changing user needs.

International Classification:

G06F 1700

US Classification:

707102

Abstract:

A user-level controlled mechanism is interposed into a read/write path of a computer system. The mechanism can be implemented as properties attached to documents. Documents having properties attached thereto have the capability of separating the content of the document from the properties which describe the document. This separation of the document content from its properties allows for a user-level access and control of the properties thereby allowing a user flexibility in organizing, storing and retrieving documents. The mechanism allows a user to arrange collections of documents wherein a single document may appear in multiple collections. The properties of the present invention are user and document specific in the sense that they are associated with the user which attached the properties and are directed to control of specific documents.

International Classification:

G06F 17100

US Classification:

707100

Abstract:

A mechanism is provided which allows a user to enhance the functionalities of system operations in a computer system that were traditionally encapsulated within the computer system, and outside the control of the user. The user is provided with the ability to build arbitrary, extensible behaviors and to have those behaviors executed on low level computer system processes after the user issues an operation request through a known input device. The mechanism may be implemented as properties which are integrated on a content and/or property read write path of the computer system.
