    Open Source Collaboration Tools and Organisational Learning: On Adopting EtherPad in Small Companies2016Inngår i: Proceedings of FLOSSEdu: FLOSS education and computational thinking workshop. Open Source Systems Conference 2016. Gothenburg, Sweden., 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Organisations could benefit from the improvements in collaborative learning and increased control gained by the use of open source software. EtherPad enables simultaneous updates on a shared document from remotely located participants. We discuss the adoption life-cycle of this open source tool in the context of a strategic intervention, with a focus on a learning agenda to guide the installation and configuration processes, and to reduce the learning curve involved in the adoption experience.

    On the Importance of Sound Architectural Practices in the Use of OSS in Software Product Lines2007Inngår i: Proceedings of the 2nd International Workshop on Open Source Software and Product Lines (OSSPL 2007), collocated with the 11th International Software Product Line Conference (SPLC 2007), Kyoto, Japan, September 10-14, 2007 / [ed] Frank van der Linden, Björn Lundell, Cosi , 2007, s. 25-32Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Software Product Line (SPL) and Open Source Software (OSS) haveemerged as successful modes of developing software. Although they appear todiffer in terms of development principles and processes, researchers andpractitioners have been increasingly emphasising the need to achieve synergiesby exploiting the ever growing repositories of OSS components for developingSPLs. While there have been calls for the SPL community to accelerate thewidespread use of OSS in SPL, less attention has been paid to how OSScommunities could increase the use of OSS components in SPL. Sincearchitectural issues are considered critical in the SPL community, we proposethat an increased attention on architectural aspects of OSS components mayprovide the confidence that organizations need in order for them to choose anduse OSS components in SPL. We identify a number of architectural practiceswhich are followed by the SPL community and discuss the possibilities for andpotential benefits of incorporating those practices in OSS developmentprocesses.

    Combining Project Management Methods: a Case Study of Distributed Work Practices2006Inngår i: Advances in Information Systems Development: Bridging the Gap between Academia and Industry / [ed] Anders G. Nilsson, Remigijus Gustas, Wita Wojtkowski, W. Gregory Wojtkowski, Stanisław Wrycza, Jože Zupančič, Springer, 2006, s. 253-264Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Distribution is a multifaceted concept and one aspect concerns the adoption of ideas from a combination of methods for project management. Such distribution imposes new demands on project management and coordination since the project management aspect is an integral part of information systems development methods. This paper reports from a case study of coordinating project management practices in a commercial development method and an in-house method for project management. In order to conduct the study of how methods are combined and utilized, one of the researchers followed a development project for six months. The general aim of the project under study is to replace the numerous system registers in use with one general register, which will aid in making system maintenance more efficient. The project also has two organisational goals: to give the team members an opportunity to use RUP in a real project setting; and to introduce new technology and a new development tool. The study highlights the importance of taking a start in current work practice as opposed to focusing on the new method as such. In summary, we stress the importance of taking a start in the work practice in terms of a method in use as opposed to method proponents’ push for new methods. Any long term change in work practices has to be internalised by the stakeholders in the practical context of method use. Hence, the case study presented here adds to the body of knowledge which distinguishes between the method as used and the method as prescribed by its proponents.

    Maintaining interoperability in open source software: A case study of the Apache PDFBox project2020Inngår i: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 159, artikkel-id 110452Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Software interoperability is commonly achieved through the implementation of standards for communication protocols or data representation formats. Standards documents are often complex, difficult to interpret, and may contain errors and inconsistencies, which can lead to differing interpretations and implementations that inhibit interoperability. Through a case study of two years of activity in the Apache PDFBox project we examine day-to-day decisions made concerning implementation of the PDF specifications and standards in a community open source software (OSS) project. Thematic analysis is used to identify semantic themes describing the context of observed decisions concerning interoperability. Fundamental decision types are identified including emulation of the behaviour of dominant implementations and the extent to which to implement the PDF standards. Many factors influencing the decisions are related to the sustainability of the project itself, while other influences result from decisions made by external actors, including the developers of dependencies of PDFBox. This article contributes a fine grained perspective of decision-making about software interoperability by contributors to a community OSS project. The study identifies how decisions made support the continuing technical relevance of the software, and factors that motivate and constrain project activity.

    On Company Contributions to Community Open Source Software Projects2019Inngår i: IEEE Transactions on Software Engineering, ISSN 0098-5589, E-ISSN 1939-3520Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The majority of contributions to community open source software (OSS) projects are made by practitioners acting on behalf of companies and other organisations. Previous research has addressed the motivations of both individuals and companies to engage with OSS projects. However, limited research has been undertaken that examines and explains the practical mechanisms or work practices used by companies and their developers to pursue their commercial and technical objectives when engaging with OSS projects. This research investigates the variety of work practices used in public communication channels by company contributors to engage with and contribute to eight community OSS projects. Through interviews with contributors to the eight projects we draw on their experiences and insights to explore the motivations to use particular methods of contribution. We find that companies utilise work practices for contributing to community projects which are congruent with the circumstances and their capabilities that support their short- and long-term needs. We also find that companies contribute to community OSS projects in ways that may not always be apparent from public sources, such as employing core project developers, making donations, and joining project steering committees in order to advance strategic interests. The factors influencing contributor work practices can be complex and are often dynamic arising from considerations such as company and project structure, as well as technical concerns and commercial strategies. The business context in which software created by the OSS project is deployed is also found to influence contributor work practices. CCBY

    Swedish Dissertations: Archived for the Future?2013Inngår i: Proceedings of International Conference on Making Sense of Converging Media (Academic Mindtrek ‘13), New York: ACM Press, 2013, s. 176-179Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The publication and preservation of doctoral dissertations is fundamental to progression of research in a field. It allows future generations to 'stand on the shoulders of giants'.

    Archiving dissertations requires to store them in a way that they will be accessible even when technologies change. Classical paper publications fulfill those requirements but have disadvantages such as the need for physical storage or distribution. An increasingly popular alternative is to store dissertations as electronic documents such as PDF files.

    In this study, we analyze the extent to which electronically available doctoral dissertations published in Sweden fulfill the basic requirements of standard conformance and applicability for long-term archiving.

    We find that only a small proportion of dissertations' electronic publications follow the Swedish National Archive's requirements to conform to standards made for long-term archiving. Only at one Swedish university, a significant number of electronic publications does conform to PDF/A-1b. Interestingly, conformance to PDF/A-1b correlates to properly setting the title of a PDF document and choosing a paper format different from A4 (ISO 216). This suggests that the consequences of missed compliance for long-term archiving are not commonly known and authors have to make a conscious choice for PDF/A-1b compliance.

The study describes the conditions for long-term preservation of the content of the institutional repositories of Swedish higher education institutions based on an investigation of how deposited files are managed with regards to file format and how representatives of the repositories describe the functions of the repositories.

    Method. The findings are based on answers to a questionnaire completed by thirty-four institutional repository representatives (97% response rate).

    Analysis. Questionnaire answers were analysed through descriptive statistics and qualitative coding. The concept of information infrastructures was used to analytically discuss repository work.

    Results. Visibility and access to content were considered to be the most important functions of the repositories, but long-term preservation was also considered important for publications and student theses. Whereas a majority of repositories had some form of guidelines for which file formats were accepted, very few considered whether or not file formats constitute open standards. This can have consequences for the long-term sustainability and access of the content deposited in the repositories.

    Conclusion. The study contributes to the discussion about the sustainability of research publications and data in the repositories by pointing to the potential difficulties involved for long-term preservation and access when there is little focus on and awareness of open file formats.

    Abstract [en]

    Digital signatures are important in order to ensure the integrity and authenticity of information communicated over the Internet involving different stakeholders within and beyond the borders of different nations. The topic has gained increased interest in the European context and there is legislation and project initiatives aiming to facilitate use and standardisation of digital signatures. Open standards and open source implementations of open standards are important means for the interoperability and long-term maintenance of software systems implementing digital signatures. In this paper we report from a study aiming to establish the availability and effectiveness of software provided under an open source license for digital signing and validation of PDF documents. Specifically, we characterise the use of digital signatures in Swedish Governmental agencies, report on the interoperability of open source and proprietary licensed software for digital signatures in PDF documents, and establish the effectiveness of software provided under an open source license for validation of digital signatures in PDF documents.

    Abstract [en]

    Many organisations have requirements for long-term sustainable software systems and associated communities. In this paper we consider long-term sustainability of Open Source software communities in Open Source projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a case study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. The results strongly suggest a long-term sustainable community and that there are no signs of stagnation in the project 15 months after the fork. Our analysis provides details on the LibreOffice developer community and how it has evolved from the OpenOffice.org community with respect to project activity, long-term involvement of committers, and organisational influence over time. The findings from our analysis of the LibreOffice project make an important contribution towards a deeper understanding of challenges regarding long-term sustainability of Open Source software communities.

    On Involvement in Open Standards: How Do Organisations Contribute to W3C Standards Through Editorship?2016Inngår i: Open Source Systems: Integrating Communities: 12th IFIP WG 2.13 International Conference, OSS 2016, Gothenburg, Sweden, May 30 - June 2, 2016, Proceedings / [ed] Kevin Crowston, Imed Hammouda, Björn Lundell, Gregorio Robles, Jonas Gamalielsson, Juho Lindman, Springer, 2016, Vol. 472, s. 57-70Konferansepaper (Fagfellevurdert)
    Abstract [en]

    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.

    On licensing and other conditions for contributing to widely used open source projects: an exploratory analysis2017Inngår i: OpenSym '17: Proceedings of the 13th International Symposium on Open Collaboration, New York: Association for Computing Machinery (ACM), 2017, s. 9:1-9:14Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Open source software (OSS) projects are provided under different open source licenses and some projects use other conditions (in addition to licensing terms) for contributors to adhere to. Licensing terms and conditions may affect community involvement and contributions, and are perceived differently by different stakeholders in different OSS projects. The study reports from an exploratory analysis of licensing terms and other conditions for 200 widely used OSS projects, and an investigation of the relationship between licensing terms and other conditions for contributing. We find that strong copyleft licenses are most common and are used in the majority of the projects. Further, a clear majority of the OSS projects use no specific other condition for contributing in addition to the license terms. However, a clear majority of the OSS projects supported by foundations use other conditions for contributing in addition to the license terms. Finally, use of no specific other conditions in addition to the license terms is more common for projects using strong copyleft licensing compared to projects using non-copyleft licensing.

    Abstract [en]

    Legacy file formats is an increasing concern for organisations. Therefore it is important for any company to develop sustainable strategies for data curation in order to maintain valuable digital assets. In this paper we report from a case study conducted in a company context aiming to investigate the feasibility of using Open Source approaches for curation of corporate digital assets kept in proprietary legacy file formats to open file formats. We consider different aspects of openness in a corporate strategy for maintaining digital assets. An important aspect concerns activity and company influence in an Open Source tool-chain, another concerns support for data curation of digital assets actually offered by the tool chain. We find that organisational concern over legacy file formats continues to be an issue, and that strong commercial influence on Open Source projects is no guarantee for success.

    Sustainability of Open Source software communities beyond a fork: How and why has the LibreOffice project evolved?2014Inngår i: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 89, nr 1, s. 128-145Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Many organisations are dependent upon long-term sustainable software systems and associated communities. In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

    On organisational influences in software standards and their open source implementations2015Inngår i: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 67, s. 30-43Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Context: It is widely acknowledged that standards implemented in open source software can reduce risks for lock-in, improve interoperability, and promote competition on the market. However, there is limited knowledge concerning the relationship between standards and their implementations in open source software. This paper reports from an investigation of organisational influences in software standards and open source software implementations of software standards. The study focuses on the RDFa standard and its implementation in the Drupal project.

    Objective: The overarching goal of the study is to establish organisational influences in software standards and their implementations in open source software. More specifically, our objective is to establish organisational influences in the RDFa standard and its implementation in the Drupal project.

    Method: By conduct of a case study of the RDFa standard and its implementation in the Drupal project we investigate organisational influences in software standards and their implementations in open source software. Specifically, the case study involved quantitative analyses of issue tracker data for different issue trackers for W3C RDFa and the Drupal implementation of RDFa.

    Results: The case study provides details on how and to what extent organisational influences occur in W3C RDFa and the Drupal implementation of RDFa, by specifically providing a characterisation of issues and results concerning contribution to issue raising and commenting, organisational involvement over time, and individual and organisational collaboration on issues.

    Conclusion: We find that widely deployed standards can benefit from contributions provided by a range of different individuals, organisations, and types of organisations either directly to a standardisation project or indirectly via an open source project implementing the standard. Further, we also find that open processes for standardisation adopted by W3C may also contribute to open source projects implementing specific standards.

    Responsiveness as a measure for assessing the health of OSS ecosystems2010Inngår i: Proceedings of the 2nd International Workshop on Building Sustainable Open Source Communities (OSCOMM 2010) / [ed] Hammouda, I., Tampere: Tampere University of Technology, 2010, s. 1-8Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The health of an Open Source ecosystem is an important decision factor when considering the adoption of Open Source software or when monitoring a seeded Open Source project. In this paper we introduce responsiveness as a qualitative measure of the quality of replies within mailing lists, which can be used for assessing ecosystem health. We consider one specific metric of responsiveness in this paper, and that is the response time of follow-up messages in mailing lists. We also describe a way for characterising the nature of communication in messages with short and long response times. The approach is tested in the context of the Nagios project, and we particularly focus on the responsiveness for contributors acting in their professional roles as core developers. Our contribution is a step towards a deeper understanding of voluntary support provided in mailing lists of OSS projects.

    Abstract [en]

    Model Driven Development (MDD) is widely used in the embedded systems domain, and many proprietary and Open Source tools exist that support MDD. The potential for sustainability of such tools needs to assessed prior to any organisational adoption. In this paper we report from a case study conducted in a consultancy company context aiming to investigate Open Source tools for MDD. For the company it was interesting to explore the two Open Source modelling tools Topcased and Papyrus for potential adoption. The focus for our case study is on assessing the health of the ecosystems for the two investigated Open Source projects by means of quantitative analysis of publically available data sources about Open Source projects. The health of ecosystems is an important prerequisite for a long term sustainable OSS (Open Source Software) tool-chain in the MDD area, which can aid strategic decision making for potential adoption within a company context. We have established details on the extent to which developers and users are active in two specific OSS ecosystems, and identified organisational influence for both ecosystems. We find that the investigated tools are promising regarding the health of their ecosystems, and a natural next step for the company would be to proceed with a pilot study in order to analyse the effectiveness of the investigated tools in company contexts.

    Libre software is a new world in itself, for both companies and professionals. As the use of libre software products becomes more widespread in the software industry and in other sectors which are heavily dependent on software for their activities, it is becoming increasingly important to understand how to make the most of this new world. In this article we explore some of the new issues that emerge when approaching libre software, and how companies are addressing them.

    Integrating proprietary and open-source tool chains through horizontal interchange of XMI models2007Inngår i: IEEE International Conference on Software Maintenance, 2007: ICSM 2007, IEEE conference proceedings, 2007, s. 521-522Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Model driven development has several advantages over traditional development, including simplified maintenance. We demonstrate an architecture which, through model driven engineering, allows heterogeneous distributed development of components in a mechatronics application. Key to the approach is an architecture which allows automated and dynamic component integration, together with model sharing through the transformation of XMI files.

    Simplifying maintenance by using XSLT to unlock UML models in a distributed development environment2007Inngår i: IEEE International Conference on Software Maintenance, 2007: ICSM 2007, IEEE conference proceedings, 2007, s. 465-468Konferansepaper (Fagfellevurdert)
    Abstract [en]

    XMI is a standardized format for model interchange between tools. However, XMI-based interchange currently has one great disadvantage: an XMI file exported from one tool is unlikely to import correctly into a different tool. This makes XMI unusable for moving models around in a heterogeneous development environment, leading to increased maintenance problems. We suggest using specialized XSLT transformations to bridge between the XMI dialects of tools, and report on an industrial case study in which the technique has been successfully applied.
