Luddite is a golang package that provides a micro-framework for RESTful web services. It is built around extensible, pluggable middleware layers and includes a standard Resource interface that makes it easy to implement services that comply with the Orion REST API Standards.

To run the example service:

$ make all
$ cd example
$ ./example -c config.yaml

Two types of resources are provided:

• Singleton: Supports GET and PUT.
• Collection: Supports GET, POST, PUT, and DELETE.

Resources may also implement POST actions and be made read-only. Since luddite is a micro-framework, implementations retain substantial flexibility.

Currently, the framework registers several middleware handlers for each service:

• Bottom: Combines CORS, tracing, logging, metrics, and recovery actions. Tracing generates a unique request id and optionally records traces to a persistent backend. Logging logs requests/responses in a structured JSON format. Metrics increments basic request/response stats. Recovery handles panics that occur in HTTP method handlers and optionally includes stack traces in 500 responses. Also makes the Service instance, request id, and response headers available to resource handlers as part of the request [context][context].
• Negotiation: Performs JSON (default) and XML content negotiation based on HTTP requests' Accept headers.
• Version: Performs API version selection and enforces the service's min/max supported version constraints. Makes the selected API version available to resource handlers as part of the request [context][context]. [context]: http://blog.golang.org/context

Need to document these:

• Metrics
• Schema file serving
• TLS requirements
• Min/max versioning
