Collaborative editing (CE) has been an area of continuous research since early days of CSCW. Various CE systems have been studied in academia as research vehicles to investigate key technical issues in building advanced collaborative applications. In recent years, CE techniques have been increasingly adopted and further developed in industry for supporting real-world Internet or Cloud-based CE systems/services, such as Google Docs, Codoxware, IBM OpenCoWeb, Novell Vibe, and SubEthaEdit. This workshop aims to bring together CE academic researchers, industry developers, and endusers to discuss and exchange ideas on contemporary issues in researching, developing, and adopting CE systems. We have successfully organized this workshop annually at CSCW-related conferences. This year's workshop focuses on CE issues and techniques for supporting complex real-world documents (including but not limited to rich text, xml, spreadsheet, 2D/3D digital media, CAD, video, etc.), and evaluation of CE systems for such complex real-world documents.

Interest in collaborative editing (CE) has seen a dramatic rise in recent years. The ubiquity of cloud services, crowdsourcing, and mobile devices means that today's Internet citizens are increasingly accustomed to producing and editing data in a shared network environment. While systems such as Google Drive, Microsoft Web Apps, Apache Wave and Codoxware allow users to collaboratively edit shared information, they have just begun to scratch the surface of CE's full potential. In the coming years, users will expect to be able to collaboratively create, share, and edit documents and data in a dynamic, realtime, and intuitive manor. This workshop aims to connect researchers, developers, and users to help explore the future of CE in tomorrow's information landscape. This year's workshop focuses on how researchers and industry practitioners can work together to accelerate delivery of CE capabilities to meet the needs of the typical information-age user.

Not long ago, real time collaborative editing (CE) systems were seen as a novelty to the average user, and a niche area of computer science research. Today, nothing could be further from the truth. Users are increasingly more connected and are creating more and more content online, on mobile devices, and in cloud based applications. Users are increasingly expecting collaborative editing functionalities in all of their applications. The focus of this year's workshop is: 1) to explore recent advances in the technologies that enable collaborative editing systems, 2) to evaluate the adoption of these technologies by commercial industry and the open source communities, and 3) to foster an exchange of ideas between CE researchers and enduser CE systems builders. The goal is to increase the adoption of recent technological advancements in CE research by practitioners and to have practitioners identify real-world challenges for future research.
