The Eclipse User Storage Service (aka USS) and the USS REST API were developed for the Oomph project to address the requirement to persist user-specific preferences data. The first other plugin to use it is the Marketplace Client, released with Eclipse Neon.
The Eclipse USS SDK provides an integration layer between an Eclipse RCP-based application and a backend user storage system, including APIs to authenticate the user, and store and retrieve arbitrary data with the backend service.
The Eclipse USS SDK provides a Java implementation of the USS REST API to allow for easy use of the Eclipse User Storage Service (USS) by Eclipse Foundation projects. The USS SDK handles the authentication and login capabilities required to use the USS from an Eclipse installation.
At the moment, The USS SDK is part of the Oomph project. The aim of taking it outside from Oomph is to make it independent and more visible, so more projects and plugins can use it.
The initial contribution of code will come from the Oomph project.
The code is already in EPL, with contributions and commits by Eclipse committers and contributors only.
The initial contribution can be done as soon as the project is validated.
The next step is to add the eclipse.org OpenID / Oauth feature. And then, we will focus on attracting more projects or plugins to use it.
