GraphDB Roadmap

Mission: Over the coming 12 months, GraphDB will be developed to the point where its robustness, ease of use and tool support put it on a par with the established relational database technology thus providing the pathway for semantic technology to further penetrate the corporate market place.

Roadmap: The following table shows new features, improvements and intended release dates for the next few versions of GraphDB. Customer needs and issues arising will affect this plan from time to time, but the intention is to provide a quick overview of the next few release cycles, so that GraphDB users have some indication of when they can expect certain features to be available.
