“…Figure 13 presents the ruby workflow. The workflow uses Ruby 15 scripts to create nanopublications 16 for a gene list that is associated to Huntington's disease as that was resulted from an experiment [46]. The nanopublications allow disseminating individual data as independent publications and can be uniquely identified and attributed to its author.…”

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.

The model to evaluate is a model for the preservation of digital evidence-based institutions of criminal investigations where it is essential to preserve evidence that has characteristics of the environment with the purpose of increasing the rate of admissibility of the evidence in court. This article aims to evaluate the model and its impact in terms of security, admissibility, and long-term preservation characteristics. We respond to the following research question: Does the model, implemented in a software application for a case study, raise the admissibility of digital evidence in court? Thus, a software application is developed, the unit of study is defined, and the results are analysed. The study determined that the model, when implemented properly and following the guidance of implementation of the model, raises the admissibility of digital evidence in court.

This article's objective is to screen and analyse the common models of digital preservation that exist, the elements, the degree of compliance with the general guidelines, the use of techniques and compliance with specific requirements as well as to evaluate the need for a solution to the environment of criminal investigation institutions, in the scenario that lacks a specific model. The importance of the preservation of digital objects is currently heavily analysed. Several aspects may serve to make the digital objects worthless, such as the uselessness of hardware, the deficiency of ancient computing formats to support their use, human errors and malicious software. The majority of crimes currently have a digital component, such that governments and the police are obliged by law to indefinitely hold digital evidence for a case's history. Until the presentation of the digital evidence in court, the evidence must be collected, preserved and properly distributed. The systems currently used often involve multiple steps that do not meet the demands of the growing digital world. The volume of digital evidence continues to grow, and these steps will soon become operationally and economically unfeasible for agencies responsible for performing these tasks.
