A broad based adoption of Creative Commons licenses is bound to face challenges. Some of the challenges arise from the way copyright laws in different jurisdictions are designed. Other challenges arise from either the way Creative Commons licenses are structured or due to the underlying policy considerations of information society as a whole.  This paper discusses these challenges and suggests ways of dealing with them.

In the recent years wikis have become an attractive platform for social studies of the human behaviour. Containing millions records of edits across the globe, collaborative systems such as Wikipedia have allowed researchers to gain a better understanding of editors participation and their activity patterns. However, contributions made to Geo-wikis — wiki-based collaborative mapping projects — differ from systems such as Wikipedia in a fundamental way due to spatial dimension of the content that limits the contributors to a set of those who posses local knowledge about a specic area and therefore cross-platform studies and comparisons are required to build a comprehensive image of online open collaboration phenomena. In this work, we study the temporal behavioural pattern of OpenStreetMap editors, a successful example of geo-wiki, for two European capital cities. We categorise dierent type of temporal patterns and report on the historical trend within a period of 7 years of the project age. We also draw a comparison with the previously observed editing activity patterns of Wikipedia.

Self-supporting development environments like Smalltalk and Emacs can be used to evolve the environment itself from within very direct way. In Web-based software development environments users can collaborate in creating software without having to install the environment locally. Bringing these two together and making Web-based environments self-supportive is challenging, since users have to take care not to break the system, as they are not the only ones using it.

In our previous work, we showed how context-oriented programming (COP) can be used to develop such a system completely from within itself. COP allows for dynamically adapting the base system and scope the changes as needed.
Environments aimed at end-users usually provide a scripting level above the base system. In our system, the Lively Kernel, the core is developed using modules and classes, and users create active content by direct manipulating and scripting objects on top of it. By leveraging the scripting level for the development of tools themselves, we allow users to adapt their tools, without the need to learn and adapt to the concepts of the core level.

In this paper we show how the development tools in Lively are collaboratively evolved. The publishing of objects in a shared repository of parts creates a feeling of extreme open source, as tools can be directly inspected, adapted, and republished while they are being used.

A fundamental unit of work in programming is the code contribution (“”commit””) that a developer makes to the code base of the project in work. An author’s commit frequency describes how often that author commits. Knowing the distribution of all commit frequencies is a fundamental part of understanding software development processes. This paper presents a detailed quantitative analysis of commit frequencies in open-source software development. The analysis is based on a large sample of open source projects, and presents the overall distribution of commit frequencies. We analyze the data to show the differences between authors and projects by project size we also includes a comparison of successful and non successful projects and we derive an activity indicator from these analyses. By measuring a fundamental dimension of programming we help improve software development tools and our understanding of software development. We also validate that some fundamental assumptions about software development.

Since the advent of the World Wide Web, the cultural heritage sector has undergone a series of changes. In a pilot survey among memory institutions (galleries, libraries, archives, museums) in Switzerland we have focused on two recent trends – open data and crowdsourcing – asking to what extent heritage institutions are ready to adopt open data policies and to embrace crowdsourcing strategies. The results suggest that so far, only very few institutions have adopted an open data policy. There are, however, signs that this may soon change: a majority of the surveyed institutions considers open data as important and believes that the opportunities prevail over the risks. Some obstacles, however, still need to be overcome, in particular the institutions’ reservations with regard to “free” licensing and their fear of losing control. With regard to crowdsourcing the data suggest that the adoption process will be slower than for open data. Although approximately 10% of the responding institutions seem already to experiment with crowdsourcing, there is no general breakthrough in sight, as a majority of respondents remain sceptical with regard to the benefits.

Open source licenses provide everyone with the legal right to use, study, share, and improve the technology they cover from the perspective of copyright law. However, there are occasions when open source software packages or projects primarily governed by copyright licenses come into potential conflict with patent issues, or suffer from other governance concerns regarding third-party Intellectual Property Rights (IPR). From an economic perspective it is interesting how instead of undermining adoption, such challenges have led to an increase of collaborative governance solutions in open source, perhaps inspired by how such collaboration in development and business matters has provided benefit to stakeholders. In this paper, we explore the evolution of collaborative solutions in open source business by examining actual using real world examples, and in the process illustrate how this unique approach to dealing with diverse ownership across business sectors works in practice.

Wiki technologies have proven to be versatile and successful in aiding collaborative authoring of web content. Multitude of users can collaboratively add, edit, and revise wiki pages on the fly, with ease. This functionality makes wikis ideal platforms to support research communities to curate data. However, without appropriate customization and a model to support data curation and collaborative editing of pages, wikis will fall sort in providing the functionalities needed to support collaborative work. In this paper, we present the architecture and design of a wiki platform, as well as a model that allow scientific communities, especially disaster response scientists, collaborative edit and append data to their wiki pages. Our experience in the implementation of the platform on Mediawiki demonstrates how wiki technologies can be used to support open collaboration, and how the dynamics of the FLOSS development process, its user and developer communities are increasingly informing our understanding about supporting collaboration and coordination in wiki environments. We conclude with best-practice guidelines for platform designers, and managers of systems that encourage collaborative authoring of web content.

Continuous Integration (CI) and Free, Libre and Open Source Software (FLOSS) are both associated with agile software development. Contradictingly, FLOSS projects have difficulties to use CI and software forges still lack support for CI. Two factors hamper widespread use of CI in FLOSS development: Cost of the computational resources and security risks of public CI services. Through security analysis of public CI services, this paper identifies possible attack vectors. To eliminate one class of attack vectors, the paper describes a concept that encapsulates a part of the CI system via virtualization. The concept is implemented as a proof of concept.

This paper presents research that investigated the role of conflict in the editorial process of the online encyclopedia, Wikipedia. The study used a grounded approach to analyzing 147 conversations about quality from the archived history of the Wikipedia article Australia. The study found that conflict in Wikipedia is a generative friction, regulated by references to policy as part of a coordinated effort within the community to improve the quality of articles. Finally, the paper addresses the implications of the study in light of larger questions about the quality of information online, as well as diversity and coordination in online communities.

Wikipedia is an important institution and part of the new media landscape having evolved from the collaborative efforts of millions of distributed users. This poster will present ongoing research that examines how the issues that have been highlighted by conflict within the community have shaped the evolution of Wikipedia from an open wiki experiment to a global knowledge producer. Bringing together the concepts of interpretive flexibility and generative friction with existing theories on the evolution of institutions, the research aims to present possible futures for Wikipedia as part of not only the larger Wikimedia movement, but of an open and accessible web.
