5.2. S-RAMP Server
The S-RAMP implementation is a fully compliant reference implementation of the S-RAMP specification. It provides a Java based client library that you can use to integrate your own applications with an S-RAMP compliant server. The server implementation is a conventional Java web application (WAR). The following technologies are used to provide the various components that make up the server implementation:
- JCR (ModeShape): Used as the persistence engine, where all S-RAMP data is stored. Artifacts and ontologies are both stored as nodes in a JCR tree. All S-RAMP queries are mapped to JCRSQL2 queries for processing by the JCR API. The ModeShape JCR implementation is used by default. However, the persistence layer is pluggable allowing alternative providers to be implemented in the future.
- JAX-RS (RESTEasy): Used to provide the S-RAMP Atom based REST API. The S-RAMP specification documents an Atom based REST API that implementations should make available. The S-RAMP implementation uses JAX-RS (specifically RESTEasy) to expose all of the REST endpoints defined by the specification.
- JAXB: Used to expose a Java data model based on the S-RAMP data structures defined by the specification (S-RAMP XSD schemas).

5.2.1. S-RAMP Server Authorization
When accessing the S-RAMP Atom API, the authenticated user must have certain roles. As the implementation leverages ModeShape as its persistence store by default, the authenticated user must have the following JAAS role, which is required by ModeShape:
admin.sramp
Additionally, the S-RAMP Atom API web application requires the user to have the following role:
overlorduser
