System requirements-OSS components: matching and mismatch resolution practices – an empirical study

Developing systems by integrating Open Source Software (OSS) is increasingly gaining importance in the software industry. Although the literature claims that this approach highly impacts Requirements Engineering (RE) practices, there is a lack of empirical evidence to demonstrate this statement. To explore and understand problems and challenges of current system requirement–OSS component matching and mismatches resolution practices in software development projects that integrate one or more OSS components into their software products. Semi-structured in-depth interviews with 25 respondents that have performed RE activities in software development projects that integrate OSS components in 25 different software development companies in Spain, Norway, Sweden, and Denmark. The study uncovers 15 observations regarding system requirements-OSS components matching and mismatch resolution practices used in industrial projects that integrate OSS components. The assessed projects focused mainly on pre-release stages of software applications that integrate OSS components in an opportunistic way. The results also provide details of a set of previously unexplored scenarios when solving system requirement–OSS component mismatches; and clarify some challenges and related problems. For instance, although licensing issues and the potential changes in OSS components by their corresponding communities and/or changes in system requirements have been greatly discussed in the RE literature as problems for OSS component integration, they did not appear to be relevant in our assessed projects. Instead, practitioners highlighted the problem of getting suitable OSS component documentation/information.

Characteristics of Open Source Software Projects for the General Population: Reciprocity and Network Effects

In this paper, we conceptualize about, and empirically test for, differences between the more traditional Open Source Software (OSS) projects that are aimed towards techies-only and the projects that are aimed towards the general population. By drawing upon the theories of Reciprocity and Network Effects, we propose that OSS projects for techies-only are more likely to exhibit characteristics that are explained by balanced reciprocity, whereas OSS projects for the general population are more likely to show characteristics that are rooted in generalized reciprocity. In addition, we propose that local network effects can be used to explain certain characteristics of OSS projects for techies-only, whereas direct and indirect network effects shape the corresponding characteristics of OSS projects for the general population differently. The findings support our hypotheses and lead us to recommend actions for OSS projects targeted towards the general population, as well as suggestions for future research.     

Open Source Software: All You Do Is Put It Together

As of 1 August 2007, SourceForge.net hosted more than 150,000 registered open source software projects, and many more projects are available on other sites. With so many OSS choices, it might seem that building a new application is only a matter of finding the appropriate projects and putting them together. We've developed the adaptable multi-interface communicator infrastructure to support rapid prototyping from OSS components. AMICO is based on existing middleware platforms for component integration, but it focuses on pragmatic aspects of OSS integration often absent from existing integration platforms. AMICO satisfies requirements based on our experiences in solving practical problems in several projects. AMICO OSS is based on a publish-subscribe infrastructure for integrating loosely coupled services. In such infrastructures, a publisher updates a shared data repository. The loosely coupled approach can be highly adaptable when using simple data structures, because new applications can use existing data in the model and add their own without breaking the infrastructure. Components communicate by exchanging events through a shared data repository consisting of named slots called variables. Components can update the variables and register for notifications about variable changes. Modules can also derive new variables by processing existing ones.     

A data/knowledge paradigm for the modeling and design of operationssupport systems

The paper develops the Smart Object paradigm and its instantiation, which provide a new conceptualization for the modeling, design, and development of an important but little researched class of information systems, operations support systems (OSS). OSS is the authors' term for systems which provide interactive support for the management of large, complex operations environments, such as manufacturing plants, military operations, and large power generation facilities. The most salient feature of an OSS is its dynamic nature. The number and kind of elements composing the system as well as the mode of control of those elements change frequently in response to the environment. The abstraction of control and the ease with which complex dynamic control behavior can be modeled and simulated is one of the important aspects of the paradigm. The framework for the Smart Object paradigm is the fusion of object-oriented design models with declarative knowledge representation and active inferencing from AI models. Additional defining concepts from data/knowledge models, semantic data models, active databases, and frame based systems, are added to the synthesis as justified by their contribution to the ability to naturally model OSS at a high level of abstraction. The model assists in declaratively representing domain data/knowledge and its structure, and task or process knowledge, in addition to modeling multilevel control and interobject coordination     

Open source software licenses: Strong-copyleft, non-copyleft, or somewhere in between?

Studies on open source software (OSS) have shown that the license under which an OSS is released has an impact on the success or failure of the software. In this paper, we model the relationship between an OSS developer's utility, the effort that goes into developing an OSS, his attitude towards the freedom to choose an OSS license, and the choice of OSS license. We find that the larger the effort to develop OSS, the more is the likelihood that the OSS license would be free from restrictions. Interestingly, the result holds even when all OSS developers prefer restrictive licenses or less-restrictive license. The results suggest that least-restrictive or non-copyleft license will dominate other types of OSS license when a large effort is required to develop derivative software. On the other hand, most-restrictive or strong-copyleft licenses will be the dominant license when minimal effort is required to develop the original OSS and the derivative software.

Open source software success: Measures and analysis

Despite a growing body of research on OSS production, much remains to be learned. One important issue concerns the measures of OSS project success and its determinants. In this paper, we empirically study the determinants of OSS success as measured by the number of subscribers and developers working on an OSS project. Furthermore, we demonstrate that our model forecasts these success measures more accurately as compared to a naive model.We find that OSS projects that develop software to work on Windows/UNIX/Linux operating systems, and developed using C or its derivative languages experience larger increase in subscribers and attract more developers than projects that do not have these characteristics. OSS projects with semi-restrictive licenses have fewer subscribers and attract fewer developers. Interestingly, OSS projects that accept financial donations and are targeted at IS/IT professionals have more subscribers than others, although these characteristics do not affect the developer base. The number of subscribers and developers increases with the age of the OSS project. Finally, the impact of developers on subscribers and subscribers on developers is positive and significant.
