Traditional distributed collaboration frameworks based on assumption of static collaboration and usage patterns cannot fulfil many new requirements imposed by today's collaboration with heterogeneous and ever-changing environments and computing contexts. In this paper, we describe a collaboration framework, called as EkSarva, which enables adaptability by providing context-awareness through a set...
We present an architecture for a next-generation Internet based on Web services and utility computing. This architecture would be realised as a series of open but interacting markets. We present a scenario whereby these markets could develop, driven by economic forces and market opportunities, exploiting technologies developed in e-Science and grid computing. We argue that, if properly realised such...
Enterprise workers are increasingly becoming mobile and this is creating scenarios for anytime-anywhere collaboration, using different sets of devices, services and modalities at different times. One of the challenges is to enable seamless contextual collaborations, where people get the best possible collaboration experience at all times. This paper describes a method for generating the most appropriate...
The international workshop on Emerging Technologies for Next-generation GRID (ETNGRID) is at its third edition. The number of submitted papers, as well as the topics tackled, clearly show the attention the research community has towards Grid computing, an interest which is continuously growing. We provide here a brief overview of the papers that have been presented at the workshop, summarizing the...
The increased complexity of products and production processes as well as market developments require models of networked organisations that enable mutual tuning and continuous improvements at the process level. In addition, divergent goals of network partners might require distributed decision making. Collaboration frameworks help to meet those requirements, however, need to be developed in a structured...
Business process modeling has been developed for the single enterprise or more generally, for single actor environments. Furthermore, most process model management tools presume the usage within a closed community (e.g. a single enterprise), that is characterized by a central control unit (hierarchical management structure). Within collaborative businesses, there is a lack of centralized structures...
In the article, the approach towards an integrative process modelling for collaboration networks is presented. The authors depict a possibility for global modelling of business processes with a module-based modelling language in combination with established event-driven process chains for local modelling. The approach helps to create and to distinguish model knowledge for its collaborative application
Service oriented architecture approach in general and the Web services technology in particular are becoming more and more important in modern networked organisations and virtual organisations (VO). However, it is not enough to have the business functionality of the partners packaged as (Web) services; there is also a need for business-aligned order of interaction between these services a.k.a. business...
Grid technologies not only provide the infrastructure to collaborate among virtual organizations to share heterogeneous resources but also provide a service oriented paradigm for business and social software development. In this paper, we present an agent based efficient and adaptive design for our meteorological data portal system, called meteo-data grid and its implementation using grid technology...
Enterprises more and more collaborate with other enterprises in networked organizations. Such collaborations require the business processes of the partner companies to be aligned and integrated with each other, both on a process and data level in a dynamic, ad-hoc fashion. At the first International Workshop on Process Integration of Collaborative Enterprises (PINCET) at WETICE 2006 several approaches...
It is argued in this position paper that a workflow management system is potentially a powerful solution to bring more flexibility to the management of business processes. At the same time, the technical difficulties of integrating such systems in a business environment prevent this advantage to materialize up to this day
The goal of the ProFlex workshop is to bring together practitioners and researchers from different communities who share an interest in flexibility of process-aware information systems and team support. This workshop report gives an overview of the presented papers that address various flexibility issues of process-aware information systems.
Distributed and collaborative applications are rapidly converging towards the adoption of a computing paradigm based on service-oriented architectures, according to which an application results from the composition of a set of services in execution on networked server hosts. In this context, a major challenge for collaborative businesses and application service providers is to provide services with...
Peer-to-peer architecture is currently an attractive solution for facilitating the use of collaboration software without any server. Multicasting is usually proposed for group communication, such as IP multicasting, which is the most efficient way to disseminate collaboration data as it eliminates traffic redundancy and improves bandwidth utilization. But due to scalability and deployment issues,...
Peer-to-peer networks exist with the volunteering cooperation of various entities on the Internet. Their self-structure nature has the important characteristic that they make no use of central entities to run as coordinators and the benefits of this cooperation can be enjoyed equally by all the members of the community with the assumption that they all make right use of the protocol. In this study...
The second International Workshop on Collaborative Peer-to-Peer Information Systems, COPS06 was held in Manchester University as part of WETICE-2006. It was the second meeting devoted to the study of the emerging field of Cooperative Information Systems and P2P networks or Cooperative P2P-based Information Systems (COPS). The first edition has been focused on trust management and middleware. This...
Our research into secure managed extranets was motivated by the requirements of companies (possibly competitors) needing to collaborate on occasion because transient business windows present mutual opportunities. Our contributions towards satisfying these requirements are twofold: (i) we present a service-construct abstraction based on what we term a 'collaborative context' where authorized participants...
The following topics are dealt with: enterprise collaboration; agent-based computing; peer-to-peer computing; information system; mobile collaboration; grid architecture; resource management; data security; semantic technology
This paper presents the E, F, I approach for the development of a contextual definition of a Web service. E, F, and I stand for environment, feature, and interaction, respectively. By default, a Web service resides in an environment E where it acts and reacts. In this environment E, the Web service exposes its features F to peers or other components for awareness and visibility purposes. Finally,...
