The EHRI Data Backend

A business layer and JAX-RS resource classes for managing EHRI data.

Integrates with the Neo4j graph database via a server plugin.

The raison d'être of the EHRI web service backend is to make the job of the front-end easier by performing the following functions:

• serialising and deserialising domain-specific object graphs
• handling cascade-delete scenarios for objects that are dependent on one another
• calculating and enforcing access control and action-based permissions on both individual items and item-classes in two hierarchical dimensions: user/group roles, and parent-child scopes
• maintaining an audit log of all data-mutating actions, with support for idempotent updates

For documentation (a work-in-progress, but better than nothing) see the docs:
