The on-Line System, also known as NLS (oN-Line System), was a revolutionary computer system developed by [[Douglas Carl Engelbart]] and his team at the [[Augmentation Research Center]] ([[ARC]]) in the 1960s. It was an integral part of Engelbart's vision of the [[Dynamic Knowledge Repository]] ([[DKR]]), which aimed to enhance human intellect and collaboration through computer technology. The NLS was designed as a networked computer system that allowed multiple users to work together on shared documents and projects in real-time. It introduced several groundbreaking concepts and features that are now fundamental to modern computing. One of the key features of [[NLS]] was its interactive, graphical user interface. Unlike other systems at the time that used text-based command lines, NLS employed a mouse-driven interface with windows, icons, menus, and hyperlinks. This made it much more intuitive and user-friendly. NLS also introduced the concept of [[hypertext]], which allowed users to link documents together through embedded references or [[hyperlinks]]. This made it easy to navigate between related information and created a non-linear way of accessing knowledge. Another significant aspect of NLS was its collaborative capabilities. Users could simultaneously edit documents, see each other's changes in real-time, and communicate through chat or video conferencing. This fostered collaborative work environments long before the advent of tools like Google Docs or Slack. Engelbart envisioned [[Dynamic Knowledge Repository|DKR]] as a comprehensive system that would not only facilitate collaboration but also augment human intellectual capabilities. The on-Line System included features like outline processing, document version control, shared calendars, task management tools, and even video teleconferencing. Although the on-Line System never gained widespread adoption outside of research institutions like ARC, its influence can be seen in many aspects of modern computing. Concepts like graphical user interfaces, hypertext, collaborative editing, and video conferencing have become integral parts of our digital lives today. Engelbart's vision for the DKR and the on-Line System laid the foundation for the development of personal computers, the internet, and many other technologies that shape our world today. # References ```dataview Table title as Title, authors as Authors where contains(subject, "Hypertext") or contains(subject, "Hyperlink") or contains(subject, "Topological Note-taking") ```
