The term "middleware" has been widely used for many years while people are still using it with different meanings. Looking at Wikipedia, it is said:

"Middleware is computer software that connects software components or applications. It is used most often to support complex, distributed applications. It includes web servers, application servers, content management systems, and similar tools that support application development and delivery. Middleware is especially integral to modern information based on XML, SOAP, Web services, and service-oriented architecture."

Upperware?

there is still no definition within Wikipedia...if a Middleware is connecting software components then we may presume that Upperware, Upper being higher than Middle, is a software connecting people who have developped softwares to connect software components. In other words, an Upperware may appear as a software connecting people's brains or at least the "concepts" they have in mind (their brain) in order to get a common understanding and be able to elaborate/create together new concepts....
