In these systems, many patches are submitted to improve the quality. To verify the quality, voting is commonly used by contributors; however, there still exists a major problem, namely, that reviewers do not always simply reach a broad agreement. In our previous study, we found that consensus is not usually reached, implying that an individual reviewer’s final decision usually differs from that of the majority of the other reviewers. In this study, we further investigate the reasons why such situations often occur, and provide suggestions for better handling of these problems. Our analysis of the Qt and OpenStack project datasets allow us to suggest that a patch owner should select more appropriate reviewers who often agree with others’ decisions. %B Open Source Systems: Integrating Communities: 12th IFIP WG 2.13 International Conference, OSS 2016, Gothenburg, Sweden, May 30 - June 2, 2016, Proceedings %I Springer International Publishing %C Cham %P 97–110 %@ 978-3-319-39225-7 %U http://dx.doi.org/10.1007/978-3-319-39225-7_8 %R 10.1007/978-3-319-39225-7_8 %0 Book Section %B Open Source Systems: Integrating Communities: 12th IFIP WG 2.13 International Conference, OSS 2016, Gothenburg, Sweden, May 30 - June 2, 2016, Proceedings %D 2016 %T In-between Open and Closed - Drawing the Fine Line in Hybrid Communities %A Mäenpää, Hanna %A Kilamo, Terhi %A Männistö, Tomi %E Kevin Crowston %E Hammouda, Imed %E Lundell, Björn %E Gregorio Robles %E Gamalielsson, Jonas %E Juho Lindman %X Today, the community driven development model extends into a variety of new, often web based collaborations. Among these are hybrid open source development set ups in which various online tools are used to facilitate cooperation between virtual teams of commercial and voluntary stakeholders. As yet, how these relationships form and evolve is not understood extensively. This article presents a longitudinal case study of a smartphone startup that founded its early product development strategy on reliance on feedback from its customers through a web based question and answer forum. With this, the company managed to extend values typical for open source communities to support development of its proprietary software. Our main findings include that the challenge in similar settings lies in striking the right balance between the open and the proprietary – while overt openness may risk the competitive advantage of a company, leaving too much behind closed boundaries can create unnecessary friction in the relationship. %B Open Source Systems: Integrating Communities: 12th IFIP WG 2.13 International Conference, OSS 2016, Gothenburg, Sweden, May 30 - June 2, 2016, Proceedings %I Springer International Publishing %C Cham %P 134–146 %@ 978-3-319-39225-7 %U http://dx.doi.org/10.1007/978-3-319-39225-7_11 %& In-between Open and Closed - Drawing the Fine Line in Hybrid Communities %R 10.1007/978-3-319-39225-7_11 %0 Book Section %B Open Source Systems: Integrating Communities: 12th IFIP WG 2.13 International Conference, OSS 2016, Gothenburg, Sweden, May 30 - June 2, 2016, Proceedings %D 2016 %T On Involvement in Open Standards: How Do Organisations Contribute to W3C Standards Through Editorship? %A Gamalielsson, Jonas %A Lundell, Björn %E Kevin Crowston %E Hammouda, Imed %E Lundell, Björn %E Gregorio Robles %E Gamalielsson, Jonas %E Juho Lindman %X Over the years, a number of open standards have been developed and implemented in software for addressing a number of challenges, such as lock-in, interoperability and longevity of software systems and associated digital artefacts. Understanding organisational involvement and collaboration in standardisation is important for informing any future policy and organisational decisions concerning involvement in standardisation. The overarching goal of the study is to establish how organisations contribute to open standards development through editorship. Specifically, the focus is on open standards development in W3C. Through an analysis of editorship for all W3C recommendations we contribute novel findings concerning organisational involvement and collaboration, and highlight contributions from different types of organisations and countries for headquarter of each organisation. We make three principal contributions. First, we establish an overall characterisation of organisational involvement in W3C standardisation. Second, we report on organisational involvement in W3C standardisation over time. Third, we establish organisational collaboration in W3C standardisation through social network analysis. %B Open Source Systems: Integrating Communities: 12th IFIP WG 2.13 International Conference, OSS 2016, Gothenburg, Sweden, May 30 - June 2, 2016, Proceedings %I Springer International Publishing %C Cham %P 57–70 %@ 978-3-319-39225-7 %U http://dx.doi.org/10.1007/978-3-319-39225-7_5 %& On Involvement in Open Standards: How Do Organisations Contribute to W3C Standards Through Editorship? %R 10.1007/978-3-319-39225-7_5 %0 Conference Paper %B The International SymposiumProceedings of The International Symposium on Open Collaboration - OpenSym '14 %D 2014 %T Initial Results from the Study of the Open Source Sector in Belgium %A Viseur, Robert %Y Dirk Riehle %Y Jesus M. Gonzalez-Barahona %Y Gregorio Robles %Y Möslein, Kathrin M. %Y Schieferdecker, Ina %Y Cress, Ulrike %Y Wichmann, Astrid %Y Hecht, Brent %Y Nicolas Jullien %X The economy of FLOSS (Free and open source software) has been the subject of numerous studies and publications, particularly on the issue of business models. However, there are fewer studies on the local networks of FLOSS providers. This research focuses on the ecosystem of Belgian FLOSS providers and, more specifically, their geographical distribution, the activities, technologies and software they support, their business models, their economic performance and the relationships between companies. The research is based on a directory containing nearly 150 companies. This directory led to the creation of a specialized search engine that helped to improve annotation. The research also uses financial data provided by the Belgian Central Balance Sheet Office. The initial results of this study show a concentration in major economic areas. The businesses are more active in the services and are heavily involved activities such as infrastructure software and Web development, activities which were common in the early years of free software development. Services for the support of business software is also common. A first analysis of the graph of relationships between providers' websites highlights the role that is played by the multinational IT companies, by FLOSS editors, by commercial FLOSS associations and especially by the Walloon centers of competence that offer vast training catalogs that are dedicated to FLOSS. This research opens up many perspectives for improving the automation of the company directory updates, the analysis of the relationship between enterprises, and the automation of the financial analysis of companies. %B The International SymposiumProceedings of The International Symposium on Open Collaboration - OpenSym '14 %I ACM Press %C Berlin, GermanyNew York, New York, USA %P 1 - 5 %@ 9781450330169 %!

Gonzalez-Barahona %Y Gregorio Robles %Y Möslein, Kathrin M. %Y Schieferdecker, Ina %Y Cress, Ulrike %Y Wichmann, Astrid %Y Hecht, Brent %Y Nicolas Jullien %X Around the world national and municipal governments launch open data initiatives with declared goals like increased efficiency, transparency or economic growth. However, although little of these effects have been proven, more and more administrations open up their datasets to the public. The dissertation project describes this phenomenon as the ongoing institutionalization of digital openness in the field of public sector information. With empirical evidence from three case studies in large European cities the research project intends to theorize how NGOs, hackers and certain civil servants turn open data into an institution, which more and more public bodies feel the need to adapt to. %B The International SymposiumProceedings of The International Symposium on Open Collaboration - OpenSym '14 %I ACM Press %C Berlin, GermanyNew York, New York, USA %P 1 - 2 %@ 9781450330169 %!

Gonzalez-Barahona %A Herraiz Tabernero, Israel %X Based on the empirical evidence that the ratio of email messages in public mailing lists to versioning system commits has remained relatively constant along the history of the Apache Software Foundation (ASF), this paper has as goal to study what can be inferred from such a metric for projects of the ASF. We have found that the metric seems to be an intensive metric as it is independent of the size of the project, its activity, or the number of developers, and remains relatively independent of the technology or functional area of the project. Our analysis provides evidence that the metric is related to the technical effervescence and popularity of project, and as such can be a good candidate to measure its healthy evolution. Other, similar metrics -like the ratio of developer messages to commits and the ratio of issue tracker messages to commits- are studied for several projects as well, in order to see if they have similar characteristics. %B 10th Working Conference on Mining Software Repositories %8 05/2013 %U http://oa.upm.es/14698/1/paper.pdf %> https://flosshub.org/sites/flosshub.org/files/paper_1.pdf %0 Conference Paper %B Fourth International Workshop on Mining Software Repositories (MSR'07:ICSE Workshops 2007) %D 2007 %T Impact of the Creation of the Mozilla Foundation in the Activity of Developers %A Jesus M.

What happened to the group of developers during this transition? There was any significant impact on its activity or composition? To answer these questions, we have performed an analysis of the CVS repository of Mozilla, using the CVSAnalY tool, finding little on activity, but dramatic changes in the the composition of the development team. %B Fourth International Workshop on Mining Software Repositories (MSR'07:ICSE Workshops 2007) %I IEEE %C Minneapolis, MN, USA %P 28 - 28 %@ 0-7695-2950-X %R 10.1109/MSR.2007.15 %> https://flosshub.org/sites/flosshub.org/files/28300028.pdf
