Open Source, Collaborative Rich-Text, Web-Based Editor Almost Available

johanneswilm writes: Open source web-based editors such as CKEditor and TinyMCE have been available for more than a decade, and some closed source collaborative editors such as Google Docs have been available since 2007. Creating open source, collaborative, rich-text, web-based editors has proven difficult due to lack of standardization of the lower-level browser features. Now Marijn Haverbeke, the developer behind the popular CodeMirror has started such an editor, called Prosemirror, financed through a crowd-funding campaign. Meanwhile the W3C has installed a task force to rapidly standardize and fix the features needed in browsers to easily create richtext and semantic editors.
