Emphasis seems to have been entirely on communication between processes. Added various things to C and the compiler dealt with arranging the calls to the tuple space. The Javaspaces project grew out of ideas from Linda. A simple service for cooperative computing. The first Jini service.
Emphasis is on communications.
They appear to have removed one of my objections to Linda, that tuple type signatures need to be known by applications. At least that is how I interpret the words at least on this page . T Spaces is a network communication buffer with database capabilities. It enables communication between applications and devices in a network of heterogeneous computers and operating systems. T Spaces provides group communication services, database services, URL-based file transfer services, and event notification services.
