What is real-time collaborative editing, and what are some of the most compelling technologies available in the space? In the inaugural TAG Team Talk, hosted by Preston So (Contributing Editor, Tag1 Consulting), we conduct a wide-ranging discussion about both the business prerogatives and technical ins-and-outs of real-time collaborative editing and its landscape today, with our guests Kevin Jahns (creator of Yjs and collaborative editing expert at Tag1 Consulting), Fabian Franz (Senior Technical Architect and Performance Lead, Tag1 Consulting), and Michael Meyers (Managing Director, Tag1 Consulting). In this talk, we explore collaborative editing, diving into how it works and some of the challenges borne by shared editing. Through the lens of Yjs, a real-time collaboration framework that supports not just text but also collaborating on drawings and 3-D models, we take a look at Operational Transformation (OT) and how implementing Conflict-free Replicated Data Types (CRDT) drives decentralized server approaches in collaborative editing and supports more robust distributed applications with true real-time support.
