Dealing with forward and backward jumps in workflow management systems

Workflow management systems (WfMS) offer a promising technology for the realization of process-centered application systems. A deficiency of existing WfMS is their inadequate support for dealing with exceptional deviations from the standard procedure. In the ADEPT project, therefore, we have developed advanced concepts for workflow modeling and execution, which aim at the increase of flexibility in WfMS. On the one hand we allow workflow designers to model exceptional execution paths already at buildtime provided that these deviations are known in advance. On the other hand authorized users may dynamically deviate from the pre-modeled workflow at runtime as well in order to deal with unforeseen events. In this paper, we focus on forward and backward jumps needed in this context. We describe sophisticated modeling concepts for capturing deviations in workflow models already at buildtime, and we show how forward and backward jumps (of different semantics) can be correctly applied in an ad-hoc manner during runtime as well. We work out basic requirements, facilities, and limitations arising in this context. Our experiences with applications from different domains have shown that the developed concepts will form a key part of process flexibility in process-centered information systems.

Monk,knight or artist? the archivist as a straddler of a paradigm

The contextual approach gives the impression that we are moving into the 21st century with three competing scientific traditions of interpretation. Another understanding is the systemic view, which indicates a paradigm with complementing traditions of interpretation, depending on ontological level. The paradigm of archival science is, like that of many other sciences, influenced by positivism, systems theory and hermeneutics. The relevance of the paradigm depends on personal beliefs. The hermeneutic understanding of archival science emphasizes the context and deconstructs central concepts. Hermeneutics emphasizes the influence of conceptual changes and technological advances on perception. Hermeneutics stresses the need for a socio-cultural and historical orientation of archival science. The positivistic tradition is coloured by the myths about an ideal science. This is reflected firstly in the analogy comparing archives with nature, and secondly in the deductive method. Positivism is instrumental in its demands for distinct definitions of concepts and its insistence on the record as the basis of archival science. The flexibility of systems theory highlights the complex relations between context and record. Systems theory can, at its best, serve as a meeting-place for researchers, archivists and users and accordingly form the basis for new knowledge and theory formation. Systems theory enables a materialistic/dialectic epistemology based in reality and inspired by other relevant sciences. The result may be the foundation of a systemic-functionalist archival science with activities, records creation and evidential values in focus.

Knowledge acquisition for temporal-abstraction mechanisms

We describe three general temporal-abstraction mechanisms needed for managing time-stamped data: point temporal abstraction (a mechanism for abstracting several parameter values into one class); temporal inference (a mechanism for inferring sound logical conclusions over a single interval or two meeting intervals); and temporal interpolation (a mechanism for bridging non-meeting temporal intervals). Making explicit the knowledge required for temporal abstractions supports the acquisition of problem-solving knowledge needed for planning, plan execution, problem identification and plan revision. These mechanisms are implemented in the RÉSUMÉ system, and will be used in the context of our ongoing PROTÉGÉ-II project, whose goal is to generate knowledge-based systems automatically, as well as the appropriate knowledge-acquisition tools, custom-tailored to acquire the specific domain and task knowledge needed by the specific problem-solving method chosen for the task.

Cloudy with a Chance of Open Source: Open Source Integrated Library Systems and Cloud Computing in Academic Law Libraries

Integrated library systems (ILSs) have been fundamental to library workflow in both technical services and public services for decades. However, many of the proprietary ILSs currently on the market do not provide law libraries with the flexibility and adaptability necessary to keep pace with advances in technology. Some law libraries are considering abandoning proprietary ILSs and implementing one of the nascent open source ILSs that have sprung up in the last few years. As the lines blur between hardware and software, many organizations are trading in-house information technology infrastructure and personnel for full-service cloud hosting. This article examines these trends for those contemplating a move to an open source ILS and/or cloud computing.     

Many Languages,Many Workflows: Mapping and Analyzing Technical Services Processes for East Asian and International Studies Materials

This case study addresses a workflow analysis project undertaken in the International Studies and Asia Library technical services areas of the University of Michigan Library. The analysis was an opportunity to document existing technical services practices in three primary workflow areas: acquisitions/receiving, cataloging, and cataloging maintenance. International Studies began the project independently, and subsequently consultants were hired to work with both International Studies and Asia Library to find efficiencies and barriers, identify solutions, and propose future changes in non-Roman-language cataloging workflows. This article provides an account outlining the project background, implementation, outcomes, challenges, and lessons learned.     

Virtuoso: A virtual single processor programming system for distributed real-time applications

The Virtuoso programming system is a real-time programming framework that offers the same high level API across all target platforms from single processor to multiprocessor systems. A very fast nanokernel that manages a set of light context processes is at the heart of the system. These nanokernel processes combine the speed of an interrupt Service Routine with the flexibility of a task and reduce considerably the latency of the application.

Utilizing Systems Development Methods in Archival Systems Research: Building a Metadata Schema Registry

This paper discusses the use of systems development research methods in the context of ongoing research that is formulating a specification for a metadata schema registry. The paper extrapolates from this discussion how such methods can be utilized in archival systems research and how such an approach differs from commercial systems engineering. In particular, the paper suggests that adopting a user-centred prototyping approach in a research context allows for exploration of the interplay between theory and practice, advancing the practice, while also offering new insights into theoretical concepts. It argues that these research methods are of increasing interest to the archival profession in order to conceptualise and realise the tools necessary to support recordkeeping and archival processes in digital environments.

The OHDEP Project: Creating a Shared Catalog for the Northeast Ohio Depository

In 2011, the Northeastern Ohio Cooperative Regional Library Depository completed a pilot project that created a shared catalog for depository holdings. The project, coordinated by the Northeastern Ohio Cooperative Regional Library Depository Implementation Group, has paved the way for the remaining four Ohio depositories to contribute their depository holdings to the shared catalog. This paper describes the motivation for the project and the planning, implementation, and impact of a shared catalog on depository workflow and service at the Northeast Ohio Regional Depository. It also highlights implications for the improved storage capacity through statewide deduplication projects.
