The document summarizes open source software research activities at the Norwegian University of Science and Technology (NTNU). The research focuses on software engineering, reuse, and off-the-shelf components. Key projects include an ITEA project on open source adoption in industry, case studies on Gentoo and open standards, surveys of open source and off-the-shelf software use, and exploring open source in education and art. The document outlines findings and lessons learned from NTNU's open source software research.

6. 1967-1977: DoD/DARPA’s development of Arpanet / Internet TCP/IP protocols -- open and distributed development, anti-authoritarian “ counter culture” .

7. 1978-85: Openness spread through Berkeley’s adaptation of Unix, with built-in Internet protocols and generous BSD licenses with all source provided.

8. 1985: Free / Open software: int’l movements (Stallman).

9. 2000: Social computing and creative commons for knowledge work – standardized formats for “zero-cost”, digital information: Wikipedia, the world is ”flat”, ...

10. 2008: 1,5 billion Internet users, 3 billion w/ mobile phones.

12. Over 30 portals with domain-specific COTS/OSS software.

13. New way of making open ICT standards : rough consensus and (two implementations of) running code.

14. Over 50 licensing schemes.

15. Business model: open and shared source supported by a cooperative foundation; separate payable services. Ex. Apache web server.

16. Success criteria: for provider, for code integrator

18. OSS participant: assists the provider in more technical work – the OSS “idea” of joint, altruistic work

19. OSS integrator: makes new software system by re-using OSS software/components

20. OSS user: may download “free” (not open) binary software on a private computer, e.g. Acrobat

23. Develop for reuse: make assets / components

24. Develop with reuse: CBSE using these assets

26. Spread novel work practices & software architectures

29. 2000-: New global “bazaar” of COTS/OSS

30. 2003-08: Industrial surveys on OTS reuse Norway, Germany, Italia, China Developer panels and follow-up interviews with qualitative data to give insight

31. Research instruments and raw data: “gone open” – please repeat our studies!!

34. Problems: effort estimation, integration, debugging, customer non-participation, licensing, company policies, how to classify components (ontologies)

36. Gentoo: OSS release management tool, scripts, 300 co-developers in 40 countries

37. Worked as co-developer for two years; distributed, participative, “in-process” field study

38. Remote debugging: mutual guesswork, as “sense-making”, informal processes

39. Data: diaries, emails, IRC/version logs

44. To all kinds of customers

45. Large companies more often than small

50. No licenses fees

53. Recommendations

54. Informal searches

55. “ Surveillance” of the OSS community

58. Used ARM’s platform for embedded graphics.

61. SVG Tiny – A mobile profile targeting light weight mobile devices

62. Open standards and the application SVG Tiny application Application size ~20.000 LOC Open Standards PNG JPEG XML11 SMIL XLINK DOM3 Other W3C standards... PC platform ARM platform

67. High degree of application portability. Less effort

70. Sonic Onyx Project (mobile phones)

71. The Flyndre Project

72. SArt: art and open source software

74. The prize award will take place at this year’s festival for art and technology in Trondheim, Trondheim Matchmaking, the 16th - 18th of October.

75. 1st prize 2000 €, 2nd prize 1500 €, 3rd prize 1000 €
