Hi, I would love to create a port of Webmachine [1] in Haskell so I can learn the language and in the meanwhile create something useful. The problem is, I don't know how I would design such a system in Haskell. Simply put, webmachine is a library in Erlang which let's you create a REST API by binding resources to URI's. The resources have sane defaults, defined with functions, like `resource_exists`, `service_available` and `is_authorized`. You can override these functions per resource to create your own API. Webmachine will then create the appropriate response when a request comes in. I have been thinking how to implement such a system in Haskell, and I have come up with the following. First of, use WAI with Warp to handle the `Request` -> `Response` cycle. That was easy to come up with, but I'm still struggling with the following question: What would a `Resource` be in Haskell? I need something that lets me define sane defaults which I can override per resource. Should I have a `Resource` typeclass which defines all the default functions? Or is there a better way to accomplish this? I hope the above was a bit clear, would appreciate any insights! [1]: http://wiki.basho.com/Webmachine-Resource.html -- Petar Radosevic | @wunki
