InfoGrid is a Web Graph Database with a many additional software components that make the development of REST-ful web applications on a graph foundation easy. InfoGrid is open source, and is being developed in Java as a set of projects:
Develops the GraphDatabase at the heart of InfoGrid. Can be used as a standalone graph database or in addition to the other InfoGrid projects.
Provides an abstract common interface to storage technologies such as SQL databases and distributed NoSQL hashtables. This enables an InfoGrid GraphDatabase to persist its data using any of several different storage technologies but with the same API for application developers.
REST-fully maps the content of a GraphDatabase to browser-accessible URLs. Viewlets allow developers to define how individual objects and sub-graphs are rendered. The project also implements a library of Viewlets, and the MeshWorld and NetMeshWorld example applications.
Defines a library of reusable object models that can be used as schemas for InfoGrid applications.
Implements the Probe Framework, which enables application developers to treat any data source on the internet as a graph of objects. This project also implements a library of Probes for common data formats.
Collects common object frameworks and utility code used throughout InfoGrid.
