Mission: Over the coming 12 months, OWLIM will be developed to the point where its robustness, ease of use and tool support put it on a par with 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 OWLIM. 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 OWLIM users have some indication of when they can expect certain features to be available.
