Bearing Point Consulting just published a study on the use of open source software in the automotive industry. It shows how open source is on the rise, no surprise. Martin Helmreich, a student of mine, did most of the work, and I guided study conception and evaluation. Here are links to the German version and the English version. I’m particularly proud about this news coverage. It is our first Chinese news coverage!

The Business of Open Models
I’m at beautiful Schloss Dagstuhl once again this week, for a seminar on “Open Models as a Foundation of Future Enterprise Systems”. I was asked to spin some thoughts on what the Open Models Initiative could learn from open source. The result is a short but sweet presentation on “the business of open models”. My maybe obvious statement is that for open models to be sustainable, they’ll need a business model. My suggestion is to create developer foundations like Apache or Eclipse for this. The slides are available as a PDF and through Slideshare, see below:
Call for Papers: HICSS-46 Minitrack on Open Movements
OPEN MOVEMENTS:
FLOSS, OPEN CONTENTS, OPEN ACCESS AND OPEN COMMUNITIES
Conference Site: Grand Wailea Maui
Dates: 7-10 January 2013
HICSS conferences are devoted to the most relevant advances in the information, computer and system sciences and encompass developments in both theory and practice. Accepted papers may be theoretical, conceptual, tutorial or descriptive in nature. Those selected for presentation will be included in the Conference Proceedings published by the IEEE Computer Society.
Additional detail about the conference may be found on the HICSS primary web site: http://www.hicss.hawaii.edu
This mini-track covers all aspects of the Open Movement phenomena, such as:
Why Open Source is Good for German Software Businesses
I’m on the expert advisory committee of one of the German parties for the current “Internet Enquette”, a commission tasked by the German parliament with suggesting future directions for Germany’s stance toward the Internet and everything digital. At a meeting this evening, a lobbyist confided in me: “Open source is bad for German software vendors!” I gasped. He couldn’t be further from the truth. If this was mechanical engineering or electrical engineering, he’d be right. ME? EE? Germany is top. Software? Not so. Beyond a few selected highlights, Germany is an also-ran internationally. When it comes to software product businesses, German companies would benefit significantly if the dice would be rolled again. Anything that upsets the current order can only be an improvement over the current state of affairs. Open source does just that. More power to open source business models!

Developer Belief vs. Reality: The Case of the Commit Size Distribution
Abstract: The design of software development tools follows from what the developers of such tools believe is true about software development. A key aspect of such beliefs is the size of code contributions (commits) to a software project. In this paper, we show that what tool developers think is true about the size of code contributions is different by more than an order of magnitude from reality. We present this reality, called the commit size distribution, for a large sample of open source and selected closed source projects. We suggest that these new empirical insights will help improve software development tools by aligning underlying design assumptions closer with reality.

Business Risks and Governance of Open Source in Software Products (in German)
Titel: Geschäftsrisiken und Governance von Open-Source in Softwareprodukten
Zusammenfassung: In fast jedem Softwareprodukt, auch in großer Standardsoftware, sind heute Open-Source-Komponenten enthalten. Die Hersteller dieser Software müssen die Geschäftsrisiken, die mit der Integration von Open-Source-Software in kommerzielle Produkte verbunden sind, verstehen und vernünftig managen. Dieser Artikel zeigt ein Modell verschiedener rechtlicher, technischer und sozialer Risiken auf, die durch unkontrollierten Einsatz von Open-Source-Software entstehen und erläutert ausgewählte Erfolgsmethoden der Open-Source-Governance, die von führenden Firmen angewandt werden. Das Modell ist das Analyseergebnis von fünf mit großen deutschen Softwareherstellern geführten Interviews sowie weiterer Literaturrecherche.

THE 8th INTERNATIONAL CONFERENCE ON OPEN SOURCE SYSTEMS
Hammamet, Tunisia, 10-13 September 2012
Scope of OSS 2012
Over the past two decades, Free/Libre Open Source Software (FLOSS) has introduced new successful models for creating, distributing, acquiring and using software and software-based services. Inspired by the success of FLOSS, other forms of open initiatives have been gaining momentum. Open source systems (OSS) now extend beyond software to include open access, open documents, open science, open education, open government, open cloud, open hardware, open artworks and museum exhibits, open innovation and more. On the one hand, the openness movement has created new kinds of opportunities such as the emergence of new business models, knowledge exchange mechanisms, and collective development approaches. On the other hand, the movement has introduced new kinds of challenges, especially as different problem domains embrace openness as a pervasive problem solving strategy. OSS can be complex yet widespread and often cross-cultural. Consequently, they require an interdisciplinary understanding of their technical, economic, legal and socio-cultural dynamics.
Cloud Computing is not a Business Model
I’m at the Dagstuhl Seminar “Information Management in the Cloud” where I keynoted about cloud computing businesses models. Given that I’m hardly a cloud computing expert this may seem like a stretch, however, the organizers had asked me to talk about my open source experience and relate this to cloud computing. This perspective turned out to be surprisingly fruitful. By realizing that both open source and cloud computing are disruptive innovations that enable a new generation of business models, I believe I was able to draw reasonable conclusions on the future of cloud computing from the history of open source. I reason by analogy, and here are the main conclusions:
Design and Implementation of the Sweble Wikitext Parser: Unlocking the Structured Data of Wikipedia
Abstract: The heart of each wiki, including Wikipedia, is its content. Most machine processing starts and ends with this content. At present, such processing is limited, because most wiki engines today cannot provide a complete and precise representation of the wiki’s content. They can only generate HTML. The main reason is the lack of well-defined parsers that can handle the complexity of modern wiki markup. This applies to MediaWiki, the software running Wikipedia, and most other wiki engines. This paper shows why it has been so difficult to develop comprehensive parsers for wiki markup. It presents the design and implementation of a parser for Wikitext, the wiki markup language of MediaWiki. We use parsing expression grammars where most parsers used no grammars or grammars poorly suited to the task. Using this parser it is possible to directly and precisely query the structured data within wikis, including Wikipedia. The parser is available as open source from http://sweble.org.
Keywords: Wiki, Wikipedia, Wiki Parser, Wikitext Parser, Parsing Expression Grammar, PEG, Abstract Syntax Tree, AST, WYSIWYG, Sweble.
