An Architecture to Support Learning, Awareness, and Transparency in Social Software Engineering
- 1. An Architecture to Support Learning, Awareness, and Transparency in Social Software Engineering Wolfgang Reinhardt Sascha Rinne University of Paderborn Institute of Computer Science

- 3. Social Software Engineering • ambivalent term • social activities represent a substantial part of daily development work • developers not only communicate, they connect through shared artefacts • social connections to people inside and outside the project © Wolfgang Reinhardt, University of Paderborn • other projects, knowledge bases, bulletin boards, developer lists etc. • domain experts do often not reside within the own organisation 3 Wolfgang Reinhardt
- 4. Learning and KM in software projects © Wolfgang Reinhardt, University of Paderborn • learning and understanding takes place by sharing of information and ad hoc exchange of short messages • inter-project networks are very important for learning in groups 4 Wolfgang Reinhardt
- 5. Collaborative Development Environments (CDE) „A virtual space wherein all stakeholders of a project - even if distributed by time or distance - may negotiate, brainstorm, discuss, share knowledge, and generally labor together to carry out some task, most often to create an executable deliverable and its supporting artifacts“ Booch & Brown, 2003 © Wolfgang Reinhardt, University of Paderborn • mostly focussed on one single project • support most stages of a developer‘s work • several stages of maturity, most mature CDEs „encourage a vibrant community of practice“ 5 Wolfgang Reinhardt
- 6. Existing approaches • Trac and Assembla • Focussed on single projects • Lists of recent actions • Sourceforge and Github © Wolfgang Reinhardt, University of Paderborn • sites that handle multiple projects • free and paid hosting • main tools for software development included (tracker, version control, file mgmt.) 6 Wolfgang Reinhardt
- 7. Lack of Transparency and Awareness • many systems / tools used during software project • lists of events are hard to understand • many events not interesting for all people involved • common focus on single projects, no support for project-spanning exchange © Wolfgang Reinhardt, University of Paderborn • no easy way of finding domain experts and contact persons • community often resides outside the hosting platform • found help is externalised somewhere else, cannot be reused 7 Wolfgang Reinhardt
- 9. Basic ideas and goals • Platform that hosts multiple projects • easy creation of new project for anyone • allowing project-spanning exchange of expert knowledge and experiences • embedding in a vibrant community © Wolfgang Reinhardt, University of Paderborn • Mashups as design pattern • leaving subsystems as they are and integrate events • enhancing artefact- and person awareness and make process more understandable and transparent 9 Wolfgang Reinhardt
- 10. Organisational Requirements • embedding of project-related activities in a community-context • Community-embedded Cooperative Development Environment (CCDE) • easy adding of new developers • using commonly well-known software without making adaptions to it © Wolfgang Reinhardt, University of Paderborn • automatic creation of instances of all required tools • allowing project-spanning expert exchange 10 Wolfgang Reinhardt
- 11. Data sources in SE projects • Repository • Instant Messaging • Issue Tracker • Audio/Video-Conferencing • Wiki • Social Bookmarks • Roadmap Planning • RSS Feeds © Wolfgang Reinhardt, University of Paderborn • Blog / Microblog • Bulletin boards • E-Mail • Shared Whiteboards • Calendar • ........ 11 Wolfgang Reinhardt
- 12. Mashup as design pattern • using standard software to meet organisational and technical requirements • Repository: Subversion • Wiki: MediaWiki • Blog: Wordpress © Wolfgang Reinhardt, University of Paderborn • Microblog: StatusNet aka Laconi.ca • Issue Tracker, Roadmap planning, source code browser: Trac • integration via a meta-navigation bar 12 Wolfgang Reinhardt
- 13. Event-based architecture • subsystems serve as EventProvider • adapter provides basic event data for eCopSoft core • analyzers investigate according action / artefact more deeply • semantical analysis of text-based artefacts, code-analysis and people © Wolfgang Reinhardt, University of Paderborn tagging • IntegrationLayer • association of events / users / projects • provides the API 13 Wolfgang Reinhardt
- 14. Semantic Web Approaches • storage of all users and events in Artefact-Actor-Network • layers of systems consolidated artefact network • semantical relations between artefact / users consolidated social network • interconnecting project spaces © Wolfgang Reinhardt, University of Paderborn isReferencedBy isSupervisorOf referencing isSupervisedBy Organization isUsed owner isAuthor modfier uses Projectspace A Projectspace B Projectspace C 14 Wolfgang Reinhardt
- 15. Overall architecture (very schematical) © Wolfgang Reinhardt, University of Paderborn 15 Wolfgang Reinhardt
- 16. Creating Awareness & Transparency © Wolfgang Reinhardt, University of Paderborn 16 Wolfgang Reinhardt
- 17. Widget-like User Interface © Wolfgang Reinhardt, University of Paderborn 17 Wolfgang Reinhardt
- 18. What is still to do?
- 19. Conclusion • embedding a CDE into a community • supporting knowledge sharing and individual learning through ad-hoc communication © Wolfgang Reinhardt, University of Paderborn • Mashup of various well-known tools to support the development process • connecting multiple separate projects 19 Wolfgang Reinhardt
- 20. Outlook • End implementation ;) • Complex Event Processing (CEP) • aggregate events to gain a deeper understanding or to alarm people in the project (traffic light system) © Wolfgang Reinhardt, University of Paderborn • field test of the platform with student groups at UPB • roll out as open platform for all students, employees and working groups at the UPB • assess the usage and quality of project-spanning helps • Web-based and Desktop Widgets that allow staying up-to-date 20 Wolfgang Reinhardt
