Web Service using REST API

Create a simple RESTful web services that accepts artifacts and stores them based on their id. The web service should have the following structure:


Methods	Resource	Description
GET	/store/api/v1.0/artifacts	returns a list of artifacts as well as their associated id
GET	/store/api/v1.0/artifacts/{id}	returns information about the file (date, location on disk)
POST	/store/api/v1.0/artifact/{id}	accepts as payload the artifact itself (uploads it to the service)
DELETE	/store/api/v1.0/artifact/{id}	delete artifact with the current id
GET	/store/api/v1.0/artifacts/{id}/fetch	returns the file itself

You can use whatever technology you deem necessary (Flask, NodeJS, Jersey, Java Servlets etc.)
All responses should be in JSON format (except when the item is returned)
HTTP Status codes should be appropriate to the given context
Artefacts should be stored on the computer file systems and renamed to the id used in the resource
- If the directory is does not exist the service should create it
- BONUS: How would you modify the resource structure so that artifacts could be grouped or versioned?
BONUS: Because you could never trust user input think on how you can verify if the file name is in a certain format (using predefined web platform methods is allowed).
