On designing a people-oriented constraint-based workflow language

Frank Leymann, Tobias Unger, Sebastian Wagner
2010 Central-European Workshop on Services and their Composition  
However, this rigidity is not always appropriate for people-oriented workflows.  ...  In this paper, we suggest an approach to design peopleoriented workflows via constraints to make them more flexible.  ...  Constraints This section gives a brief overview about control-flow constraints that can be used along with task models to design a people-oriented workflow.  ...

Flexibility as a Service [chapter]

W. M. P. van der Aalst, M. Adams, A. H. M. ter Hofstede, M. Pesic, H. Schonenberg
2009 Lecture Notes in Computer Science  
However, a "one size fits all" approach is likely to fail because, depending on the situation (i.e., characteristics of processes and people involved), different types of flexibility are needed.  ...  This paper proposes the Flexibility as a Service (FAAS) approach which is inspired by the Service Oriented Architecture (SOA) and our taxonomy of flexibility.  ...  Activities and constraints on activities are the key elements of a constraint-based model.  ...

Toward Process Modeling in Creative Domains

Jörg Becker, Milan Karow, Felix Müller-Wienbergen, Stefan Seidel
2009 Americas Conference on Information Systems  
The study belongs to the design science paradigm; the discussion is grounded in a theory that explains the nature of processes that rely on creativity.  ...  Process modeling has emerged as a widely accepted approach in order to reduce organizational complexity in organizations.  ...  The discussion of this design-oriented approach is based on a theoretical model of creativity-intensive processes. The paper is structured as follows.  ...

Research challenges on person-centric flows

Tobias Unger, Hanna Eberle, Frank Leymann
2010 Central-European Workshop on Services and their Composition

XML-based Representation of Agile Workflows

Mirjam Minor, Daniel Schmalen, Ralph Bergmann
2008 Multikonferenz Wirtschaftsinformatik  
On the other hand, the workflow engine requires a workflow representation that can be processed, made persistent, and exchanged in a straight-forward way.  ...  For the difficult task of adapting the workflows, a modelling language that is easy to understand is essential.  ...  A more suitable solution is a tree-oriented representation of the workflow instances based on the building-block property of the modelling language and based on XML technology.  ...

Collaborative scientific workflows supporting collaborative science

Shiyong Lu, Jia Zhang
2011 International Journal of Business Process Integration and Management  
This paper presents a disciplinary definition of this term, discusses the opportunities, requirements, and challenges of collaborative scientific workflows for the enablement of scientific collaboration  ...  The convergence of the above two trends naturally leads to the concept of collaborative scientific workflows.  ...  Existing scientific workflow languages and authoring tools are primarily designed to support automated scientific processes based on Web services and Grid services.  ...

Semantics through language sharing

Jessica Rubart
2008 Proceedings of the hypertext 2008 workshop on Collaboration and collective intelligence - WebScience '08  
A web semantics space is proposed that supports comparison of approaches with respect to language sharing.  ...  Both directions, the Semantic Web and Folksonomies, focus on language sharing. It is argued that to build holistic hypermedia systems these language kinds need to be integrated or mapped.  ...  Schema-based Hypertext Schema-based hypertext utilizes typed hypermedia elements and can place constraints on allowed instances.  ...

An Architectural Approach to End User Orchestrations [chapter]

Vishal Dwivedi, Perla Velasco-Elizondo, Jose Maria Fernandes, David Garlan, Bradley Schmerl
2011 Lecture Notes in Computer Science  
To address this problem, this paper proposes a composition approach based on an end user specification style called SCORE.  ...  Service-Oriented Architecture (SOA) is a widely used mechanism that can support such forms of compositions as it allows heterogeneous systems to be wrapped as services that can then be combined with each  ...  However, studies have shown that such users spend about 40% of their time on programming activities [5] , meaning that a large community of people are spending a lot of their time on programming tasks  ...
