Rule sets are managed as a web service. A web service request having at least a body and an endpoint address is received from a client. The endpoint address includes a service description parameter and a parameter identifying a path to a given rule set in a rule set. The body of the web service request is parsed to determine whether the body identifies a first type of method or a second type of method. If a first type of method is identified, a service description file is dynamically generated in a format specified by the service description parameter in the web service request. The service description file is based on the rule set path, information from the rule set database and model data. If a second type of method is identified, the identified rule set is executed. The first type of method may be a GET method while the second type of method may be a POST method.
