REST API Server¶

The Arvados API server provides controlled access to the Arvados subsystems. Its responsibilities include:

• Authenticating users (people) and clients (programs) using OAuth2 and client registration
• Authorizing each transaction (applying the permission model)
• Enforcing constraints on certain object properties (e.g., Collection UUID must equal MD5)
• Assigning UUIDs to objects

The API server is implemented in Ruby on Rails, with a PostgreSQL database.
