I am working on a new product... XRE ... an Xml Based Rules engine
This is going to allow software developers to separate Application logic, from Business rules. Thus giving your systems much more flexibility.
The product is still in beta, along with a Web Service companion, and a Rule IDE. The web service will serve the purpose of providing users with the latest build of the Engine for testing purposes... all you've got to do, is pass the Xml Rule blob as a string, and you get an Xml formatted response.
Of course the IDE will have native support for the Web service.
So well see where it goes from here.
