PLATINE is a synchronous and distributed cooperative platform for remote collaboration. It was developed since 1998 and has been used in European and French projects. PLATINE offers mechanisms for asynchronous and synchronous collaboration and includes components for session preparation, chat, videoconferencing, application sharing, and a shared whiteboard. The presentation demonstrates its use for an e-learning use case, discusses transferring its technology under an open source license, and describes lessons learned from the project including a lack of resources for completion but useful applications in research projects.

- 3. 1. PLATINE description • Offers a lot of mechanisms that can be used in different contexts: e-learning, co-design, cooperative work, ….. • Software platform used to support remote collaboration among users. • Two main kinds of interactions can be found within collaborative groups: – asynchronous collaboration, that does not require the group members to be present at the same time; – synchronous collaboration, where remote users work at the same time. • PLATINE is mainly devoted to synchronous collaboration. • Developed since 1998, used and deployed in European and French projects.

- 4. 1. PLATINE description • 3 kinds of components – A module for off-line session preparation – Asynchronous session state display with an “asynchronous” chat – Synchronous components • a synchronous session state display • a multi user visioconference • a multipoint chat • an application sharing • a shared whiteboard • a session manager • A PLATINE session is composed of – an asynchronous phase, – a synchronous phase. • Some roles can be defined for one session, and the chairman attribute can be assigned to some roles. • The chairman can manage the synchronous phase of a session.

- 5. 1. PLATINE description • Technical characteristics – Mainly developed using JAVA – External components: • VNC for application sharing • VIC and RAT alternatives for the visioconference tool – Automatic deployment for session participants • JAVA WebStart – Multicast visioconference • Optional reflector module November 17 2009 FOSSa - Grenoble 5
- 6. 1. PLATINE description • Requirements – Hardware: Pentium (or Centrino) PC minimum 1Ghz, 512 Mbytes RAM – Input/output multimedia devices: webcam, microphone, headset, ... correctly configured and installed. These devices should be recognized by jmstudio (from jmf2.1.1e) – Operating Systems: Windows XP , Fedora , MacOSX – Java : • You can use jre 1.4.2_10 version (less than jre1.5.0 version) . • On your WebStart install, you have to verify the selected jre version • 1.4.2-11 for the Java Runtime Environment (see item J2SEv1.4.2_11) • 2.1.1e for the Java Multimedia Framework November 17 2009 FOSSa - Grenoble 6
- 7. 2. Use case demonstration • Lab@Future (IST project 2002-2005) objectives: – The experiments realized correspond to learning cases where students gain knowledge by themselves. – Teachers are present in the same student session to answer to students and to remotely help them in case of difficulty. – Difficulties appear in handling the experiment specific tool but also while resolving the problem. • Experiment from the mechatronics domain using the FluidSim software November 17 2009 FOSSa - Grenoble 7

- 15. 3. Technology transfer • Observations • PLATINE is a prototype developed in a research lab in order to demonstrate new transport protocols and new cooperative protocols • No human ressources apart from research projects • We have not found any company to support the industrial completion of the prototype November 17 2009 FOSSa - Grenoble 15
- 16. 3. Technology transfer • Which result can be transferred ? • Some PLATINE components for academic or industrial partners • Why this choice ? • In the fields of network transport protocols and of computer supported cooperative work (CSCW), the researchers need communicating components • PLATINE components can be used, so we decide to share them easily • Which licence ? • CeCILL-B because it « follows the principle of the popular BSD license and its variants (Apache, X11 or W3C among others). In exchange for strong citation obligations (in all software incorporating a program covered by CeCILL-B and also through a Web site), the author authorizes the reuse of its software without any other constraints.. » http:// www.cecill.info/index.en.html November 17 2009 FOSSa - Grenoble 16
- 17. 3. Technology transfer • PLATINE website • Source code for the whole PLATINE • Users guides: install and admin and user guidelines http://www.laas.fr/PLATINE November 17 2009 FOSSa - Grenoble 17
- 18. 3. Technology transfer • PLATINE on PLUME-Feather (RELIER project) http://projet-plume.org/en/relier/platine-0 http://projet-plume.org/relier/platine November 17 2009 FOSSa - Grenoble 18
- 19. 4. Learned lessons • Unfortunate aspects – Not enough time and human ressources at LAAS to complete our platform – No community created – Not enough time to support external projects • Tokushima University (Japan): cooperation with a phd student (2004-2006) • Lakehead University (Canada): cooperation with a teacher after the ED-MEDIA Conference 2005 (2005-2006) November 17 2009 FOSSa - Grenoble 19
- 20. 4. Learned lessons • Nice surprises – A very good entry point for new research projects: • 2002-2005: IST Lab@Future using all PLATINE components + automatic deployment with JavaWebStart • 2006-2008: IST Sat6 using JVisioConference + SIP • 2004-2008: IST EuQoS using JVisioConference + QoS • 2007-2010: ITEA UseNET using Jchat + automatic deployment for mobile phones (J2ME, OSGi, Android, …..) – Always available, interesting for a lot of people: • 892 reads of French RELIER card since 09 2008, • 299 reads of English card since 04 2009 November 17 2009 FOSSa - Grenoble 20
- 21. 5. Conclusion • PLATINE : an enriching experience from both technical and human point of view • A nice way to introduce me in RELIER project November 17 2009 FOSSa - Grenoble 21
