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

Features:

• 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).
