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
• providing a GraphQL API
• providing an OAI-PMH repository

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

• All the docs
• Installing and running from the code repository
• Importing data

For getting up and running quickly, Docker is the recommended approach. A local server can be started on port 7474 and an administrative user account "mike" with the following command:

sudo docker run --publish 7474:7474 --env ADMIN_USER=mike -it ehri/ehri-rest
