Deployment of applications conforming to application data sharing and decision service platform schema

Systems, methods, and software are disclosed herein for facilitating deployment of a decision service for sharing application data among multiple isolated applications executing on one or more application platforms. In an implementation, a method of deploying applications conforming to a platform schema for facilitating sharing of the application data among isolated applications executing on one or more application platforms is described. The method includes receiving a request to submit a third party application to an application deployment system, identifying a validation manifest associated with a platform schema responsive to receiving the request, and automatically verifying that the third party application to conforms to the platform schema by performing a set of pre-defined validation checks. The request identifies the platform schema and platform capability information associated with the third party application. The validation manifest includes the set of pre-defined validation checks.
