RuleXpress is a repository-based tool that can be used offline or in a multi-user environment. Models are stored in a central repository and can be checked out to a local copy and then merged back. Within the tool the key organizing principle is that of a community - a group of people who share the same understanding about their vocabulary and rules. Within this you can have projects but the focus of the tool is on the activity of vocabulary/rule management as an ongoing task. The key activities are to manage vocabulary and rules or, more specifically terms, fact model, rules, decision tables and rule groups.
