Hi, I have been fiddling with this idea for some time, and I wonder if this may be the right place to ask a rather probing question!? It has been some years since my last visit to the list. I have been searching for examples using functional reactive programming to make web servers, but this proves surprisingly hard to find. I found the netwire library, but given that the last update was 2011 I am not sure I want to risk that ... So maybe I was asking the wrong question. I have a rather complex system of RDF Graphs (using Swish), with reasoners making derived graphs, and updates being made only on the original graphs. There are multiple constituent graphs to avoid having to recompute everything upon update. Now I was thinking that this looks like a typical case for FRP, with each graph a Behaviour, recomputing derived graph only when the source behaviour changes. I am not sure if I am right. Any opinions? The second part of this is the web server to allow queries (read and update) to the RDF Graphs. The first prototype uses Scotty with STM for storage, but when I add more constituent graphs, I really do not want an update to block access to other constituent graphs, which is what I thought I could avoid in an FRP model. Without much experience writing interactive stuff in Haskell, I cannot figure out how to wire the interaction between Scotty and either netwire or banana which are the two FRP libraries I have tried to comprehend. Are there any examples out there to look at? I am not really committed to any library or paradigm, except for RDF and Swish, so any ideas will be welcome, even pointing me away from everything I thought I needed ... Thanks for reading, :-- George
