## What it is
Webmachine is an Erlang application layer that adds HTTP semantic awareness on top of mochiweb, providing a clean way to build RESTful web applications. It models HTTP as a state machine of decisions so resources can declare behavior declaratively.

## Use cases
- build a REST API in Erlang
- serve HTTP resources with correct semantics like caching and content negotiation
- build a web backend on top of mochiweb
- implement HTTP-compliant services with proper status codes
- build an API server for Riak-style applications

## When to choose
- you are developing in Erlang and want principled REST/HTTP semantics
- you want declarative control over HTTP decision points like methods, caching, and negotiation
- you are already using mochiweb and want a higher-level resource model

## When to avoid
- you need a modern ecosystem with large community and frequent updates
- you are building in another language or want a mainstream framework
- you need rich middleware, WebSockets, or modern async features out of the box

## Facets
- artifact type: framework
- maturity: maintenance
- function: web-framework, http-server, routing, middleware
- domain: web-development, backend, apis
- platform: elixir, windows
- tags: rest, http-semantics, mochiweb, rebar3, erlang, linux, macos
