In an example, a system can include a web service interface (WSI) and a service directory for enabling communication between a web and non-web service. The WSI can be configured to communicate with the non-web service to receive reader data and/or writer data. The service directory can be configured to provide the WSI with non-web service subscriber data and/or non-web service publisher data for the non-web service in response to receiving the reader and/or writer data. The non-web service subscriber data identifies a web service as a subscriber of data provided by the non-web service and the non-web service publisher data identifies the web service as a publisher of data from which the non-web service is enabled to retrieve data. The WSI can be configured to provide the web service subscriber and/or publisher data to the non-web service to enable the non-web service to communicate with the web service.
