A shared-data system, such as could be used with an intranet or internet, in which a large quantity of files available in a file system are each individually assigned an identification number. This identification number is then converted into a non-location-based URL, such as a simple scalar number, which can be retained in a user's network browser. Further, each file has associated therewith an individual data object, by which an owner of a particular file can specify read and write access to the file. The system enables new users to create their own accounts to access the file system, without causing a general security breach. The use of location-independent URLs to identify files enables individual users to organize the files independently, and also avoids "stale" web links which occur when websites are reorganized.

A distributed group activity network system and corresponding method over a computer network. It synchronizes and provides access by system users to shared data files of a group activity. The distributed group activity network system comprises one or more server computers and client computers that are connected to the server computer(s) by network connections. Each of the server computers comprises a network server and a memory system. The network server runs on the server computer and provides basic network services that are available at the server computer. The memory systems of the server computers store synchronization files and shared data files of the group activity. Each of the client computers comprises a memory system and a system module running on the client computer. The system modules of the client computers use the memory systems of the client computers and the available basic network services at the server computer(s) to synchronize and provide access to the shared data files by the system users by also using the memory systems of the client computers and the available basic network services at the server computer(s) to synchronize access to and access the synchronization files.

Methods and systems for managing user information using a customized computer interface which is user centric and geared toward creating and managing a personal information portal. In one aspect, the invention provides computerized methods for organizing a representation of user activities and information and navigating through an information management system that utilizes the representation.

Conventional file-based engineering design data for an engineering model are represented by a plurality of components. Each component has a unique identifier, a set of fields, each field having a data type and a data value, and a program which interprets and modifies the fields. The plurality of components are stored in a repository of a server. The repository also stores a history of any changes made to the components. A plurality of client computers are bidirectionally connected to the server. Each client computer may obtain the current version of the components and may send locally edited versions of the components back to the server to replace the current versions in the repository. At the client computer, the user interacts with the components using conventional file-based software. Before locally edited versions of the components are committed to the server to replace the current versions, a synchronization and merging process occurs whereby the latest version of the components are downloaded to the client computer and are compared to the locally edited version of the components to detect resolvable (compatible) and unresolvable (incompatible) conflicts therebetween. The commit process is performed only if no unresolvable conflicts exist between the two versions of the components. To facilitate translation between file-based data and components, a schema is written to "wrap" each of the engineering file formats. Each schema is a set of classes that capture all of the information in the file-based data.

A design control system suitable for use in connection with the design of integrated circuits and other elements of manufacture having many parts which need to be developed in a concurrent engineering environment with inputs provided by users and or systems which may be located anywhere in the world providing a set of control information for coordinating movement of the design information through development and to release while providing dynamic tracking of the status of elements of the bills of materials in an integrated and coordinated activity control system utilizing a repository which can be implemented in the form of a database (relational, object oriented, etc.) or using a flat file system. Once a model is created and/or identified by control information design libraries hold the actual pieces of the design under control of the system without limit to the number of libraries, and providing for tracking and hierarchical designs which are allowed to traverse through multiple libraries. Data Managers become part of the design team, and libraries are programmable to meet the needs of the design group they service.

Traditional document systems use hierarchical filing structures as the basis for organising, storing and retrieving documents. However, this structure is very limited in comparison with the rich and varied forms of document interaction and category management in everyday document use. Presto is a prototype document management system providing rich interaction with documents through meaningful, user-level document attributes, such as “Word file”, “published paper”, “shared with Jim”, “about Presto” or “currently in progress”. Document attributes capture the multiple different roles that a single document might play, and allow users to rapidly reorganise their document space for the task at hand. They provide a basis for novel document systems design and new approaches to document management and interaction. In this article, we outline the motivations behind this approach, describe the principal components of our implementation, discuss architectural consequences, and show how these support new forms of interaction with large personal document spaces.

Document properties are a compelling infrastructure on which to develop document management applications. A property-based approach avoids many of the problems of traditional heierarchical storage mechanisms, reflects document organizations meaningful to user tasks, provides a means to integrate the perspectives of multiple individuals and groups, and does this all within a uniform interaction framework. Document properties can reflect not only categorizations of documents and document use, but also expressions of desired system activity, such as sharing criteria, replication management, and versioning. Augmenting property-based document management systems with active properties that carry executable code enables the provision of document-based services on a property infrastructure. The combination of document properties as a uniform mechanism for document management, and active properties as a way of delivering document services, represents a new paradigm for document management infrastructures. The Placeless Documents system is an experimental prototype developed to explore this new paradigm. It is based on the seamless integration of user-specific, active properties. We present the fundamental design approach, explore the challenges and opportunities it presents, and show our architectures deals with them.

Computational web portals are designed to simplify access to diverse sets of high performance computing resources, typically through an interface to computational Grid tools. An important shortcoming of these portals is their lack of interoperable and reusable services. This paper presents an overview of research efforts undertaken by our group to build interoperating portal services around a Web Services model. We present a comprehensive view of an interoperable portal architecture, beginning with core portal services that can be used to build Application Web Services, which in turn may be aggregated and managed through portlet containers.

Anchored conversations are maintained by a conversation coordinator that retrieves an anchor position from an artifact and maintains a position of a conversation client relative to the retrieved anchor position. The conversations are synchronous and asynchronous communications. The anchors, and hence the conversations may be moved within the artifact or to other artifacts. The conversation clients include detach and re-attach buttons that allow a conversation to be detached and reattached from/to a corresponding anchor. The conversation coordinator manages conversations anchored in any number of different applications. Each conversation is accessible either by invoking an associated anchor within a corresponding artifact (embodied as an ActiveX control, for example), or via the conversation coordinator. A database is connected to each conversation and is a silent participant maintaining a record of the conversation and any metadata regarding the conversation. The database is available for query by a user and/or the conversation coordinator.
