Contrary to expectations, we confirmed earlier findings of a wide distribution of centralizations even when examining the networks over time. The paper also provides empirical evidence that while change at the center of FLOSS projects is relatively uncommon, participation across the project communities is highly skewed, with many participants appearing for only one period. Surprisingly, large project teams are not more likely to undergo change at their centers.

This paper examines the question, "how does one empirically distinguish the core?" Being able to identify the core members of a FLOSS development project is important because many of the processes necessary for successful projects likely involve core members differently than peripheral members, so analyses that mix the two groups will likely yield invalid results. We compare 3 analysis approaches to identify the core: the named list of developers, a Bradford's law analysis that takes as the core the most frequent contributors and a social network analysis of the interaction pattern that identifies the core in a core-and-periphery structure. We apply these measures to the interactions around bug fixing for 116 SourceForge projects. The 3 techniques identify different individuals as core members; examination of which individuals are identified leads to suggestions for refining the measures. All 3 measures though suggest that the core of FLOSS projects is a small fraction of the total number of contributors.

This chapter will analyze the contribution of this body of research to determine how Coordination Theory has been used for user task analysis and modelling. Issues that will be addressed include: 1) how the theory has been applied; 2) the research areas within HCI to which it has been applied; 3) how the theory has been extended; and 4) future possibilities for the application of the theory.

In this paper, we use coordination theory to analyze coordination mechanisms in FLOSS development and compare our analysis with existing literature on coordination in proprietary software development. We examined developer interaction data from three active and successful FLOSS projects and used content analysis to identify the coordination mechanisms used by the participants. We found that there were similarities between the FLOSS groups and the reported practices of the proprietary project in the coordination mechanisms used to manage task-task dependencies. However, we found clear differences in the coordination mechanisms used to manage task-actor dependencies. While published descriptions of proprietary software development involved an elaborate system to locate the developer who owned the relevant piece of code, we found that ``self-assignment'' was the most common mechanism across three FLOSS projects. This coordination mechanism is consistent with expectations for distributed and largely volunteer teams. We conclude by discussing whether these emergent practices can be usefully transferred to mainstream practiceand indicating directions for future research.

But what do we really know about the communication patterns of FLOSS projects? How generalizable are the projects that have been studied? Is there consistency across FLOSS projects? Questioning the assumption of distinctiveness is important because practitioner-advocates from within the FLOSS community rely on features of social structure to describe and account for some of the advantages of FLOSS production. \\ To address this question, we examined 120 project teams from SourceForge, representing a wide range of FLOSS project types, for their communications centralization as revealed in the interactions in the bug tracking system. We found that FLOSS development teams vary widely in their communications centralization, from projects completely centered on one developer to projects that are highly decentralized and exhibit a distributed pattern of conversation between developers and active users. \\ We suggest, therefore, that it is wrong to assume that FLOSS projects are distinguished by a particular social structure merely because they are FLOSS. Our findings suggest that FLOSS projects might have to work hard to achieve the expected development advantages which have been assumed to flow from ``going open.'' In addition, the variation in communications structure across projects means that communications centralization is useful for comparisons between FLOSS teams.

We make the case that the answer is different treatments of metadata in different domains with different goals. A central difference between the two formats stems from the fact that digital music metadata lookup services are collaborative and automate the movement from a digital file to the appropriate metadata, while image metadata services do not. \\ To understand why this difference exists we examine the divergent evolution of metadata standards for digital music and digital images and observed that the processes differ in interesting ways according to their intent. Specifically music metadata was developed primarily for personal file management and community resource sharing, while the focus of image metadata has largely been on information retrieval. \\ We argue that lessons from MP3 metadata can assist individuals facing their growing personal image management challenges. Our focus therefore is not on metadata for cultural heritage institutions or the publishing industry, it is limited to the personal libraries growing on our hard-drives. This bottom-up approach to file management combined with p2p distribution radically altered the music landscape. Might such an approach have a similar impact on image publishing? This paper outlines plans for improving the personal management of digital images---doing image metadata and file management the MP3 way---and considers the likelihood of success.

However, conventional measures of project success are difficult to apply to Free/Libre Open Source Software projects. In this paper, we present an analysis of four measures of success applied to SourceForge projects: number of members of the extended development community, project activity, bug fixing time and number of downloads. We argue that these four measures provide different insights into the collaboration and control mechanisms of the projects.

This paper briefly describes our recent research into the practices of FLOSS development teams using social network analysis and describes my efforts to do it with free software and free methods. It will probably come as no surprise to those familiar with academic research that the stated values of openness and collegiality are often not put into practice. Academics often jealously guard "their data" and under-describe "their methods" leading to publications which, while often impressive, can be, at the margins, more like patent disclosures than documents that others can learn and build from to test and improve knowledge. Ultimately I hope that using free software and methods will lead to increased reproducibility, consistency and learning across academic studies of FLOSS and beyond. It is often said that FLOSS learnt from academia--it seems that free software methods can now teach in return.

However it is not without theoretical peril and practical pitfalls. In this paper, we outline practical lessons gained from our spidering, parsing and analysis of SourceForge data. SourceForge can be practically difficult: projects are defunct, data from earlier systems has been dumped in and crucial data is hosted outside SourceForge, dirtying the retrieved data. These practical issues play directly into analysis: decisions made in screening projects can reduce the range of variables, skewing data and biasing correlations. SourceForge is theoretically perilous: because it provides easily accessible data items for each project, tempting researchers to fit their theories to these limited data. Worse, few are plausible dependent variables. Studies are thus likely to test the same hypotheses even if they start from different theoretical bases. To avoid these problems, analyses of SourceForge projects should go beyond project level variables and carefully consider which variables are used for screening projects and which for testing hypotheses.

The protocol will allow devices to negotiate and agree on the mechanisms, methods, standards and protocols that will be used for the elements of resource sharing. These elements include, at least, Resource Description, Trust Establishment, Transaction Negotiation and the coordination systems to be used in making use of the resources. Each aspect of the resource sharing interaction would be handed off to a capable, available and agreed method or protocol.

We begin by answering perhaps the most basic question: what is the social structure of these teams? Based on a social network analysis of interactions represented in 62,110 bug reports from 122 large and active projects, we find that some OSS teams are highly centralized, but contrary to expectation, others are not. Furthermore, we find that the level of centralization is negatively correlated with project size, suggesting that larger projects become more modular. The paper makes a further methodological contribution by identifying appropriate analysis approaches for interaction data. We conclude by sketching directions for future research.

Traditionally computer networks have solved this problem through the insitutional membership of the device or the user. This is too grainy for the situation in wireless grids. It is expected that a distributed reputation system will help to solve this problem.\par The paper was written for the 2003 MIT Symposium on online reputation systems http://www.si.umich.edu/ presnick/reputation/symposium/ AD - MIT, Cambridge, MA, USA AU - Howison, James T2 - Position papers of The NSF Interdisciplinary Symposium on Reputation Mechanisms in Online Communities KW - HowisonPublications1 Y2 - April T1 - The role of reputation in virtual markets for wireless grids Y1 - 2003 ER - TY - CONF AB - This document summarizes the range of research occuring within the Wireless Grid project.

It introduces `fabbers' which are 3d printers used today in rapid prototyping new products. It describes the impact of P2P file-sharing on the music industry and the industries responses to file-sharing. The paper identifies a nascent file-sharing community through an empirical analysis of the rapid-prototyping mailing list and argues that manufacturing industries will face similar challenges to those being faced today by the music and film industries. N1 - This publication came out of my presentation at the first O'Reilly Peer to Peer conference held in San Francisco in February 2001. Marshall Burns, an entrepreneur in Fabricators and I made this presentation to the audience of over 500 ``alpha geeks'' of both the commercial and publishing species. This conference has become the well-known O'Reilly Emerging Technology conference.

This thesis attempts to get behind the hype and examine the reality of the events surrounding and shaping cyberspace today. It first moves to undermine the notion of a spontaneous technologically lead 'revolution' driven in part by unplanned 'convergence' and faceless 'market forces'. It does this throughout by emphasising strategic action taken with regard to the Internet, focusing especially on government and corporate 'agendas', such as the US Global Framework for Electronic Commerce. Rather than accepting 'market forces' as an object capable of action, as does the bulk of work in this area, this paper argues that it is the market itself which is being created---a task which can only be undertaken by real people, real corporations, and real people. It is a process which is making major political decisions.
