Welcome Messages One Step Forward to Diversity - Big Bang from Seoul! Welcome to the world of open source! You are welcomed to join this wonderful FOSS4G event held in Seoul and we wish you have a wonderful experience during your stay here in Korea. This year's FOSS4G Seoul is unique in several aspects. First, this is the first time international FOSS4G in Asia. For last 10 years FOSS4G has travelled all around the world and finally returned to the home place, Asia, where the term of FOSS4G was first conined. Second, FOSS4G event got out of Roman alphabet world and now face totally different letters and language, that is Korean. If we believe that language defines a human's way of thinking, you will see how agglutinative language speakers think and behave differently here. These kinds of uniqueness and difference will stimulate your insight and imagination eventually. Seoul team values the importance of diversity in our community. To increase diversity horizontally and vertically in FOSS4G event, we've done several things. First, we introduced discount-rate policy for the low-income economies' attendants for the first time in FOSS4G history. With this effort, more than 14 attendants were able to join this event. Second, we've tried to have as many travel grantees as possible. As a result we have 10 travel grantees from countries where we hardly see attendants. Thirdly, FOSS4G is no longer developer's exclusive conference. Now we need to embrace more diverse players around FOSS4G such as NGOs, international organisations and business enterprises. So, here's UN special session and links with Smart Geospatial Expo! We hope FOSS4G Seoul could result in new era of diversity in our community just like 'Cambrian Big Bang(explosion)'. We know this wonderful event could not be possible without supports, sponsoring and help from many people and organisations. LOC members, staffs, volunteers, sponsors, OSGeo and others who helped us, your supports and efforts never will be forgotten. Thanks again for your attending FOSS4G Seoul and have a fun! On behalf of FOSS4G Seoul LOC, Sanghee Shin Chairperson, FOSS4G Seoul 2015 4
A Week of Sharing, Learning, and Fun FOSS4G (Free and Open Source Software for Geospatial) has exploded in recent years and is a unique event that brings together international developers of innovative Open software and solutions, face-to-face with users, educators, and decision makers. Two full days hands-on workshops are always a highlight of a FOSS4G event, where you will be able to learn directly from the software developers themselves. Of course the main program will be a highlight, with speakers from all of the world dealing with topics of Open Source, Open Standards, and Open Data. But the true highlight of any FOSS4G is the networking, whether it is at a social event at night, or breaking off into a Birds of a Feather session in the afternoon, or a random meeting in the hallway of the venue; networking, sharing of ideas, talking, discussing, is the true spirit of what makes a FOSS4G event special. FOSS4G Seoul 2015 is a very special event as it is the first time that the international FOSS4G event will come to Asia. Much thanks must be given to the local organizing team here in Seoul, who have been hard at work for over a year planning this event. If you happen to see a local organizer or volunteer this week in person, be sure to thank them for their passion, they really deserve it. FOSS4G is a community where we can make friends, share laughs, learn, and talk passionately about what we love: being Open. Open Source Software means of course that the source code is available, but being Open is much more than just software, as you will see here at FOSS4G, where it also means opening your data, opening your standards, opening your organization, and opening your mind to new ideas. OSGeo (the Open Source Geospatial Foundation) exists to help promote the use and development of Open Source geospatial software, and OSGeo has happily hosted the international FOSS4G event all over the world since back in 2006. The journey of FOSS4G (Lausanne 2006, Victoria 2007, Cape Town 2008, Sydney 2009, Barcelona 2010, Denver 2011, Nottingham 2013, Portland 2014) now comes to Asia for the first time, and you're a big part of it. How exciting?! I'm so very excited to see you all here at FOSS4G Seoul this week, to meet you, to share with you, to learn from you, we will all learn together here. And we will make new friendships and connections, which are as important or more than the Open software that we will learn as well. Thank you to everyone for coming to FOSS4G Seoul! Have fun! On behalf of OSGeo, Jeff McKenna President, OSGeo 5
