Cette présentation dresse un panorama du logiciel libre : ce que c'est, les projets phares, les licences (droits et devoirs) et enfin les business models. J'ai donné cette présentation à l'école des mines pour les sensibiliser à la viabilité économique et technique de cet écosystème. Le discours orale associé à ce support permet d'illustrer les principes du free software avec mes expériences personnelles dans la fondation Eclipse et la mise au point du business model d'Obeo. English: this talk is an introduction to free software ecosystem.

Introduction sur l'Open Source
- 1. Etienne JULIOT [email_address] Conférence à l'Ecole des Mines de Nantes, le 03/01/2011
- 4. Projects
- 5. Licenses
- 7. Qu'est-ce qu'un logiciel libre ? 1. Liberté d' utiliser le logiciel pour tous les usages 2. Liberté d' étudier le logiciel donc accès au code source 3. Liberté de copier le logiciel y compris pour vendre les copies 4. Liberté de modifier le logiciel et de le redistribuer
- 8. And in practical terms? Open source means: The source code is available to the end-user
- 9. The source code can be modified by the end-user
- 10. The licensing conditions promote re-use and wide availability of the software
- 11. The cost of acquisition to the end-user is often minimal Open source software is not the same as free software but there is a large overlap ``Open source is a development methodology; free software is a social movement.'’ The Free software Foundation maintains a Free Software Definition (www.fsf.org)
- 12. What about the word « free »? Free as in “freedom”
- 13. This usually implies “free as in free beer”
- 14. Questions Does the binary need to be available?
- 15. Is it allowed for an editor to sell a free software and not provide a free access to the binary and the source code?
- 16. Do I always need to redistribute my modification?
- 17. What about intellectual property and copyright?
- 18. So why is it better? You can use it and modify it freely, for any purpose
- 19. You are not tied to any company
- 20. Even though you might not be able to modify it, somebody can do it for you

- 101. Four business models can be identified
- 102. The service model takes two forms
- 103. The services offered are of different types
- 104. The value added distribution model consists in selling a standard version of an existing product
- 105. This model offers a triple client value
- 106. The double licence model relies on a « discrimination » of the users
- 107. A variant of this model: the commercialization of an associated product
- 108. The «mutualization» model rests on the successive development of several modules…
- 109. … and generally results in the creation of a community of clients
- 111. OPEES Actors and Processes Page
- 112. Synthesis of the different business models
- 114. Usecase: Server
- 115. Usecase: Web
- 118. Usecase: DB
- 119. Usecase: compiler
- 120. Usecase: MD tooling
- 121. Specific VS Generic Business Logic Specific Infrastructure Business Logic Generic Infrastructure Specialisation (generation, transformation, designers, ...) Interoperability
- 122. Better quality
- 123. More tooling Specific Infrastructure
- 124. OpenSource isn’t a bisounours world
- 125. Bisounours process Labos SME Big Companies Substrate: open source I have a bug I reference it in OSS bugtracker I have nothing to do today: I will fix it … Hope ! This isn’t our job
- 126. OPEES Process Labos SME Big Companies Substrate: open source I have a bug I reference it in contracted bugtracker Support subcontractor makes the fix I subscribe an OSS contract support through Opees
- 127. Bisounours process Labos SME Big Companies Substrate: open source Is it interesting for SME? I do papers and prototypes Hope ! Is it interesting for customers? Hope ! ROI ? Investissment ?
- 128. OPEES Process Labos SME Big Companies Substrate: open source I want a new long term feature Is it interested for SME? Is there a new research interest ? yes I do papers and prototypes Yes Reuse/ remake no
