Introduction

Rexster is a web service that is queried using HTTP and returns JSON formatted responses. Stored traversals in a Rexster deployment are identified by URIs and are parametrized by the query parameter component of the URI. Rexster can work as a standalone web server or as a servlet through Tomcat. The general system architecture is as described in the diagram below.

Rexster is constrained to a core set of functionality. Rexster is designed specifically to allow multiple applications in a deployment environment to trigger stored graph traversals and retrieve JSON formatted results. Moreover, Rexster has classes to support score- and rank-based graph traversals.
