Esteemed Haskellers,Semantic Synchrony is an open-source knowledge graph server with an Emacs front end. It integrates with Chrome and Git. Git allows a graph to be selectively shared, as a collection of repositories. Subgraphs can be created and edited using indented plain text or Markdown; the latter allows nodes to serve double-duty as edge labels, by linking to them in section or subsection headings. The front end and server communicate using simple JSON.We are open to taking it in new directions.For hacking it, check out our invitation to coders[1].
