The application can be accessed through the browser interface for demonstration purposes of the repository's basic functionality. Once deployed (see Deploying Fedora - Complete Guide) navigate to either http://localhost:8080/rest using the one click install or http://localhost:8080/<war file name>/rest using the tomcat or jetty servers.
The primary way for applications to work with a Fedora repository is through the RESTful HTTP API.
In addition to interacting with the Fedora application via its RESTful HTTP API, all actions that affect a change in the repository result in a message being emitted. Client tooling can be created to perform asynchronous actions based on those messages.
As a starting point, tooling already exists
Fedora is built with the contributions of developers just like you. If you've found a bug, or have a feature you want to add, we would love your help. Our Guide for New Developers includes links to our project resources (source code, issue tracker, mailing lists, etc.) and our Git workflow.
