You can read about the OpenLexicon WSDL here . There is also an eclipse plug-in for web services here . You create complex application behavior with OpenLexicon’s process management. OpenLexicon can build an application reads data from a file, performs reference data lookups, validates the entire object, and then stores it in a database table. You can read about this here . Plus, you can build the application in the Wizard while writing no code! OpenLexicon also supports web services. A simple architecture diagram for OpenLexicon is included here .
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.
