“…This prototype leverages our collaborative platform for dynamic collaborative networks [1] with monitoring capabilities. It constitutes the continuation of a comprehensive framework [12], [13] that we are developing in the context of the European project IMAGINE [1]. Basically, this prototype provides the engineer of D a user interface that he uses to declaratively specify the monitoring query while calling User Defined Functions (UDF) implemented as external services (e.g.…”

Monitoring provides well established means to track the exchanged messages in cross-organizational processes. Complex Event Processing (CEP) is a technology used by monitoring systems that aims to process incoming events and generate high-level information. Current implementation of CEP has performance issues when the processing of events involves calling a composition of services to generate the required information. In this paper we develop a conceptual framework that relies on a set of patterns that maximize the parallel processing of incoming events. These patterns are used to split the composition of services into a set of blocks that can be executed in parallel while ensuring an effective correlation of the intermediate results. Our approach significantly decreases the processing time without requiring too many resources. We implemented a prototype of our framework and conducted performance evaluation in comparison with existing software.

“…To overcome the raised issues, we developed in a previous research [10] a declarative framework that uses high-level abstractions to model the collaboration contract in the context of a DMN. In this framework stakeholders use the first draft of the shared product model as a basis to define their collaboration contract.…”

The literature on product-based workflow design considers only static collaborative environments where the product model is static and does not change. However the possible evolution of the product model and thus its impact on the collaborative environment are not considered despite the importance of this evolution for innovative product design. As a result the uncontrolled changes can easily break the crossorganizational process that links the different stakeholders in the collaborative environment. In this paper we present a framework that builds the collaboration contract from the product model and supports a controlled evolution of this contract. We leverage this framework by a set of management operations (services) that enable the contract evolution and investigate how a tailoring operation will not impact the executable cross-organizational process unless this process is maintained executable by the workflow engine. These operations are provided as services by a collaborative platform and displayed through a standard-based user interface.

“…In the context of the project IMAGINE [1] the objective is to develop a collaborative platform that facilitates the collaboration between engineers during the product design phase. In previous work [6], [7], we have developed a formal framework to support and manage this collaboration. Nevertheless, the components of the associated platform cannot be selected arbitrarly.…”

Software applications that are provided through services following the Software as a service (SaaS) paradigm generally need to be compliant to some standards. In order to select the software application that provides the most conformant service interface, we develop a formal framework that tests the compliance and reports quantitative results that help experts to take the right decision. Unlike existing work that focuses on a single dimension when checking the compliance of a software application with the corresponding standard (for example the functional dimension exclusively, or the syntactic dimension exclusively), in this work we consider multiple dimensions at the same time. This provides more comprehensive results.We implemented a prototype and we tested our framework on a case study regarding the selection of software applications for our collaborative platform.
