Complex data driven experiments form the basis of biomedical research. Recent findings warn that the context in which the software is run, that is the infrastructure and the third party dependencies, can have a crucial impact on the final results delivered by a computational experiment. This implies that in order to replicate the same result, not only the same data must be used, but also it must be run on an equivalent software stack. In this paper we present the VFramework that enables assessing replicability of workflows. It identifies whether any differences in software dependencies among two executions of the same workflow exist and whether they have impact on the produced results. We also conduct a case study in which we investigate the impact of software dependencies on replicability of Taverna workflows used in biomedical research of Huntington's disease. We re-execute analysed workflows in environments differing in operating system distribution and configuration. The results show that the VFramework can be used to identify the impact of software dependencies on the replicability of biomedical workflows. Furthermore, we observe that despite the fact that the workflows are executed in a controlled environment, they still depend on specific tools installed in the environment. The context model used by the VFramework improves the deficiencies of provenance traces and documents also such tools. Based on our findings we define guidelines for workflow owners that enable them to improve replicability of their workflows.

“…In Miksa et al (2014), we defined principles of RWS design and elaborated a list of methods that constitute RWS. For the sake of the paper's completeness, we provide below the description of RWS methods and also examples of responses obtained from these methods.…”

“…To alleviate these threats and uncertainties, the concept of resilient web services (RWS) has been proposed lately (Miksa et al, 2015(Miksa et al, , 2014. RWS build on top of existing WS standards, such as Web Services Description Language (WSDL), by adding a set of methods available to the consumer that facilitate the management and use of the service over time, when changes occur.…”

Oriented Architecture has become a popular architecture in systems development, it is often implemented employing Web Services. However, the dependency especially on externally provided services can impact the reliability of a system. This is often caused by the loser coupling also implying a less stringent policy for change management and notifications. We therefore characterise the types of changes that can happen in remote services, and propose the concept of Resilient Web Services as an example on how to upgrade existing services to better support the long term stability of services and systems. Design/methodology/approach Having analysed several use cases where systems broke due to external dependencies not correctly maintained, the authors derived requirements for Resilient Web Services. Findings By means of a prototype implementation and evaluation of this solution in a case study, the feasibility of the approach was verified. Several scenarios of changes in web services were simulated and correctly identified, and responded to. Originality/value The authors propose a set of extensions to existing standards such as WSDL to improve the long-term availability of services in Service Oriented Architectures. A prototype implementation was developed for service monitoring and Resilient Web Services.
