In: OpenSym '22. - New York, NY, USA : Association for Computing Machinery (ACM). - 9781450398459 - 9781450398466

Conference paper (peer-reviewed)abstract
- Open hardware and open source software platforms bring benefits to both implementers and users in the form of system adaptability and maintainability, and through the avoidance of lock-in, for example. Development of the \riscv\ Instruction Set Architecture and processors during the last ten years has made the implementation of a desktop computer using open hardware, including open processors, and open source software an approaching possibility. We use the SiFive Unmatched development board and Ubuntu Linux, and the recorded experiences of system builders using the Unmatched board to explore the extent to which it is possible to create an open desktop computer. The work identifies current limitations to implementing an open computer system, which lie mainly at the interface between the operating system and hardware components. Potential solutions to the challenges uncovered are proposed, including greater consideration of openness during the early stages of product design. A further contribution is made by an account of the synergies arising from open collaboration in a private-collective innovation process.

On availability of Open Source Software reference implementations for standards issued by different standards setting organisations
- 2023
-
In: Joint Proceedings EURAS & SIIT 2023. - Aachen : Verlag Mainz. - 9783958864917 - 3958864910 ; , s. 97-116

Conference paper (peer-reviewed)abstract
- Software reference implementations of ICT standards have an important role for verifying that a standard is implementable, supporting interoperability testing among other implementations, and providing feedback to the standard development process. Providing reference implementations and widely used implementations of a standard as Open Source Software also promotes wide deployment in software systems, avoidance of different lock-in effects, interoperability, and longevity of systems and associated digital assets. In this paper results are reported on the availability of reference implementations and widely deployed implementations provided as Open Source Software for standards issued by different standards setting organisations. Specifically, findings draw from observations and analyses related to software implementations for identified standards issued by ETSI, IEC, IEEE, IETF, ISO, ITU-T, OASIS, and W3C.

On engagement with ICT standards and their implementations in open source software projects : the case of WebRTC
- 2022
-
In: Proceedings 26th EURAS Annual Standardisation Conference. - Aachen : Verlag Mainz. - 9783958864467 ; , s. 143-162
-
Conference paper (peer-reviewed)abstract
- Real-time communication (RTC) technologies for the web provide opportunities for individuals and organisations to work and collaborate remotely, and the need for such technologies has recently increased. Use of RTC technologies and tools for the web involves a number of challenges concerning data privacy and lock-in effects, such as dependency to specific suppliers and proprietary technologies. Use of open standards for RTC and open source software (OSS) implementing such standards can create conditions for avoiding issues related to data privacy and lock-in, and thereby provides opportunities for long-term sustainable solutions. The paper characterises how engagement with standardisation of WebRTC in the context of IETF and W3C is related to engagement with the WebRTC OSS project.

- Software reference implementations of ICT standards have an important role for verifying that a standard is implementable, supporting interoperability testing among other implementations, and providing feedback to the standard development process. Providing reference implementations and widely used implementations of a standard as Open Source Software promotes wide deployment in software systems, interoperability, longevity of systems and associated digital assets, and avoidance of different lock-in effects. In this paper results are reported on the availability of, and perceptions and practices concerning, reference implementations and widely deployed implementations provided as Open Source Software for standards issued by different standards setting organisations. Specifically, findings draw from observations and analyses related to software implementations for identified standards and policy statements, issued by ETSI, IEC, IEEE, IETF, ISO, ITU-T, OASIS, and W3C.

Towards open government through open source software for web analytics : The case of Matomo
- 2021

Journal article (peer-reviewed)abstract
- Web analytics technologies provide opportunities for organisations to obtain information about users visiting their websites in order to understand and optimise web usage. Use of such technologies often leads to issues related to data privacy and potential lock-in to specific suppliers and proprietary technologies. Use of open source software (OSS) for web analytics can create conditions for avoiding issues related to data privacy and lock-in, and thereby provides opportunities for a long-term sustainable solution for organisations both in the public and private sectors. This paper characterises use of and engagement with OSS projects for web analytics. Specifically, we contribute a characterisation of use of OSS licensed web analytics technologies in Swedish government authorities, and a characterisation of organisational engagement with the Matomo OSS project for web analytics.

Enabling OSS usage through procurement projects : How can lock-in effects be avoided?
- 2021
-
In: Open Source Systems. - Cham : Springer. - 9783030752507 - 9783030752538 - 9783030752514 ; , s. 16-27
-
Conference paper (peer-reviewed)abstract
- Formulation of mandatory requirements in procurement projects has significant influence on opportunities for development and deployment of Open Source Software (OSS). The paper contributes insights on a widespread practice amongst public procurement projects which causes problematic lock-in effects and thereby inhibits opportunities for use of OSS solutions. Through a systematic investigation of 30 randomly selected procurement projects in the software domain the paper highlights illustrative examples of mandatory requirements which cause lock-in and presents five recommendations for how requirements instead should be formulated in order to avoid causing lock-in. Findings show significant lock-in caused by current procurement practices with a stark preference for proprietary software and SaaS solutions amongst procuring organisations.

UML model interchange in heterogeneous tool environments : an analysis of adoptions of XMI 2
- 2006
-
In: ACM/IEEE 9th International Conference on Model Driven Engineering Languages and Systems. - Berlin, Heidelberg : Springer Berlin Heidelberg. - 9783540457725 - 9783540457732 ; , s. 619-630
-
Conference paper (peer-reviewed)abstract
- Heterogeneous tool environments are often a reality and it is therefore increasingly important to be able to interchange model information between tools. This is not only true concerning the natural heterogeneity resulting from distributed development contexts; the need may also arise in a tool chain and for legacy reasons. Without this possibility, there is significantly reduced flexibility, and a danger of tool lock-in. In this study we explore the use of the standardised interchange format XMI for supporting interchange of model information between heterogeneous tools. We report on the current state regarding XMI version 2.0 and greater. We find that there seems to be better support for model interchange using XMI 2.0 than for earlier versions of XMI, and speculate that one contributing factor may be the recent integrations of the Eclipse platform in UML modelling tools.

Adopting Open Source development tools in a commercial production environment : are we locked in?

Conference paper (peer-reviewed)abstract
- Many companies are using model-based techniques to offer a competitive advantage in an increasingly globalised systems development industry. Central to model-based development is the concept of models as the basis from which systems are generated, tested and maintained. The availability of high-quality tools, and the ability to adopt and adapt them to the company practice, are important qualities. Model interchange between tools becomes a major issue. Without it, there is significantly reduced flexibility, and a danger of tool lock-in. We explore the use of a standardised interchange format (XMI) for increasing flexibility in a company environment. We report on a case study in which a systems development company has explored the possibility of complementingtheir current proprietary tools with open source products for supporting their model-based development activities. We found that problems still exist with interchange, and that the technology needs to mature before industrial- strength model interchange becomes a reality.
