The growing availability of specialized web services targeting only a particular niche has resulted in the use of multiple web services by enterprises for their daily activities. It is significantly difficult for resource-crunched small enterprises to write applications to integrate with each and every dependent web service. Overcoming the missing wide scale adoption of machine readable standards (WSDL, WADL, SAWSDL), we explore the capability to integrate with numerous web services using only the basic web standards (HTTP, JSON, XML, XSD, XSLT) and declarative languages (SQL, datalog queries). In this paper, we specifically focus on the role of a generic web service wrapper to support this declarative approach to describe, query and extract enterprise data from web services.
