Two approaches have been established: SOAP (Service Oriented Architecture Protocol) and RESTful Web Services (Representational State Transfer). While SOAP bases on XML, the REST approach uses HTTP requests (which contain URLs) as interface in order to access methods which are implemented on the web server. The call parameters for the implemented methods in the web service are transferred directly in the requests.
Current research focuses on the integration of web technologies into the product development and production as well as into the underlying systems and processes. For this aim demonstrators are developed in order to access product data and product-related documents using a RESTful Web Service.
