in addition to the available XML based WSDL api, integrity should provide a JSON API to support current technology standards for web and application develpment.
This would be most valuable if the API was combined with the existing "session" information that has currently authorized a users to use the tool. In addition, the security/authorization for that user would apply to the JSON API transaction. The current limitations of the XML/SOAP interface has prevent the integration of of Integrity with other tools that we utilize in our organization.
As part of our plan to provide a new Web UI, we are working on RESTful Web Services (Although 'stateless'), so you should get this in the coming releases.
